PUMS - MD Medical Chemistry

informative and interesting way of conveying the subject which helps understanding them much easier.

Me encantó como lo ha explicado, paso a paso, de manera detallada y concisa. He aprendido mucho gracias a este video, ¡gracias!

To the point. Good organized pathway explanations. Pedagogical presentation skills.

Thank you so much, Dr Thad. You're very clever in coming up with the 'gnomes' example, which is perfect for quickly understanding Acid-base. Thanks again.

This lesson is explained very well! It's clear to me what Lineweaver-Burk plot means and how enzymes are most efficient when they have high Kcat/low Km

I like all videos & I want to more teach you about this and your lectures is so brilliant

Dr. Ahern is amazing at linking what he's about to teach to previous videos.

So far so good. The videos are easy to follow and I love the questions that pull up at the end of the videos to recall the information. Looking forward on finishing the rest of the modules in biochemistry, including all the other sections.

I've reviewed the Video, and while it provides a comprehensive overview, there are a few points that need clarification. "Fatty acid synthesis doesn't occur in the mitochondrion; it occurs in the cytoplasm, sequestered from fatty acid oxidation, simplifying the regulation of the two pathways." Clarification: Fatty acid synthesis indeed occurs in the cytoplasm, separate from fatty acid oxidation that takes place in mitochondria. This separation allows for streamlined regulation, ensuring the balance between synthesis and breakdown. "Fatty acid synthesis is chemically similar to the reverse of oxidation, involving joining, reduction, loss of water, and a final reduction, making it essentially the reverse of oxidation." Clarification: Fatty acid synthesis does indeed involve joining of acetyl and malonyl units, reduction steps, and removal of water, making it similar but not exactly the reverse of oxidation. The subtle differences in the chemical steps are crucial for the controlled synthesis of fatty acids. "The enzyme acetyl-CoA carboxylase is regulated through phosphorylation by AMP-activated protein kinase and allosteric binding of citrate, ensuring the balance between synthesis and cellular energy levels." Clarification: Acetyl-CoA carboxylase, a key enzyme in fatty acid synthesis, is indeed regulated through phosphorylation and allosteric binding of citrate. This regulation allows cells to respond to energy demands, modulating fatty acid production accordingly. "Fatty acid synthesis involves a series of steps catalyzed by the multifunctional enzyme fatty acid synthase, where individual activities within the enzyme complex work together, ensuring efficient fatty acid production." Clarification: Fatty acid synthase, a multi functional enzyme complex, plays a central role in fatty acid synthesis. Its individual activities work in harmony within the complex, allowing for the sequential addition of carbon units and the creation of fatty acids up to 16 carbons in length.

The following are the errors in the information you provided: 00:24 The general formula for monosaccharides is Cx(H2O)x, where x is equal to the number of carbon atoms in the monosaccharide. For example, the structural formula for glucose is C6H12O6, which means that it has six carbon atoms and six water molecules. 01:15 The structural formula for lactose is C12H22O11. This means that it is a disaccharide made up of two monosaccharides, glucose and galactose. 01:39 Polysaccharides are polymers of monosaccharides, but they do not necessarily have to have the same repeating sugar unit throughout. For example, amylopectin is a polysaccharide made up of glucose molecules, but it has a branched structure. Here is a corrected version of the information you provided: Carbohydrates are molecules whose name literally means hydrates of carbon. This is because monosaccharides, the simplest carbohydrates, have a ratio of one carbon atom to two hydrogen atoms to one oxygen atom, the same as water. The general formula for monosaccharides is Cx(H2O)x, where x is equal to the number of carbon atoms in the monosaccharide. For example, the structural formula for glucose is C6H12O6, which means that it has six carbon atoms and six water molecules. Disaccharides are carbohydrates that are made up of two monosaccharides. They are formed by a glycosidic linkage between the two monosaccharides. Disaccharides have the general formula C12H22O11. Examples of disaccharides include sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (glucose + glucose). Polysaccharides are carbohydrates that are made up of many monosaccharides. They are formed by glycosidic linkages between the monosaccharides. Polysaccharides have the general formula (C6H10O5)n, where n is the number of monosaccharides in the polysaccharide. Examples of polysaccharides include cellulose, starch, glycogen, and chitin. Polysaccharides do not necessarily have to have the same repeating sugar unit throughout. For example, amylopectin is a polysaccharide made up of glucose molecules, but it has a branched structure.

The lectures are not bad, they have the material, tbey are very well spoken and easy to undersgand. I find some quizz questions to not be relevant, i believe i won't be aske dthese questions on exam. And sometime the material itself feels dry. I am more of a doers, so by solving more complicated questions with the help of a professor would my learning experience much better. But over all not a bad course.

Thank you! I appreciate how you explain this material. Thank you

Great Lecturer..well explained. Every section of lectures are meticulously explained. Clearly understood.

Simple, not over-complicated and understandable, all great signs of an amazing lecture.

ok me gusto mucho esta leccion , gracias por hacer lecturio para estudiar

it's very easy and simply explained and I loved it It was very helpful

I am appreciative that Dr. Ahern took the time to update his lectures. Shows he cares. Thank you!

Recomendo pra todos que querem saber melhor sob Medina das universidades

Clear and understandable concept with actual molecules shown aswell which is very helpful.

Bio means life, chemistry means the composition of matter and energy requirements for life to exist. Chemicals and anyone

Prof Kevin Ahern is incredible! Great summary and really well explained!

It was just what I really needed I love lecturio so much

not explned wel as the topic is difficult and you made it a lot much boring

easy and complete explanation for a complex topic, you're the best!

All the lectures have been so, so helpful. Thank you so much!

Kevin is Amazing man, his body language get a lot to his explanation!

excellent explanation of topic very difficult to understand for a med student

Physiology for me was just something that, as Medicine student, I had to study... After Dr. Thad Wilson's courses, actually I'm enjoying it! Very good structure, the tone is calm, very good explanation, funny mnemonics and many useful info that I'm sure will be valuable for my proffesional future! Thank you, Dr. Wilson!!!

So easy and set in an interesting way. Very well covered

The lecture series was great over all but I was wondering if there’s an anion gap lecture regarding the calculations needed to identify a widened gap as well as the delta-delta equations. And if so why isn’t it part of the acid-based series?

Really well done! It’s very helpful to recall and reinforce basic concepts.

I have really learned. Before, I was wondering why study, or cram all those pathways and enzymes. How Professor Kevin Ahern explains and bring out concepts, Oh my God so great. He was born a teacher and just polished by learning! He never leaves behind any one, even the slow learners can pick, because once one understands the basic, the necessary complex facts can be understood quite faster! I am now thinking of mastering in Biochemistry, besides my goal of Internal medicine. To be the best Physician, Biochemistry I have understood is one of the vital tools! In my Nursing practice, we lost a 10 yr old male with Liver Cirrhosis from a liver disease, which was diagnosed in early age. Now, I am thinking of a Deficiency of the Transaldolase enzyme!! Ahh save for my little knowledge! Kind regards!

Really a great and elaborate presentation. Thanks Prof. Kevin. Now I no longer struggle in cramming Biochemistry but rather find the subject interesting. I wish I started using your lecture guide early in Medical school, but any way not yet late! Thank you once again.

Very dense lecture. Maybe a bit too in-depth in some places, but excellent discussion about the importance of carbohydrates and the key enzymes and reactions that underly the process.

Excellent review and explanations of the different vitamins and their various forms and functions.

Awesome lectures by Sir. he explain every step and every single reaction with detail thank u.

I can easily follow the sequence of information. The important details are also emphasized, making it easier for recall.

Nice delivery but as much as Dr tries to break it down,it looks a bit abstract. Perhaps some mneumonic would help

I really like the explanations and detailed structures used. The structures make it easier to understand.

Ver clear good graphics explained simply good questions best lectures

Very clear and easy to understand. I enjoyed the visuals.

great lecture, i have been a doctor for a decade but nice to review this topic with such a brilliant lecuture. Thank you so much for your help.

very precise, for a person with basic knowledge it is very helpful although I think it could be a bit difficult to understand for someone who does not know anything about these issues.

Professor Kevin make it enjoyable course; It helped not only in remembering many info that I forgot in the class, but also I did learn many new valuable information. The fact that the explanation provided by Dr. Kevin is so easy to understand and memorize, make this course very interesting.

The explanation about the carbs are very clear and detail. Which make easier for any student and professor to better understand the carbs, their pathway, and the enzymes that work in those pathways.

I am a biochemistry student, the videos on lecturio have been so amazing. The lectures are superb. The language is easily understood and in a very friendly way. The concepts are been discussed fully and appropriately. It has made me to understand biochemistry more.

ok ok ok ok ok ok ok ok ok ok ok ok

Just I need to get this course for my exam and i am progressing with Dr.Raj confidently...Thanks for all

just got the structure formation of a f actin support epithelial

I like how Dr. Kevin discussed all the topics, simple and easy to understand.

ten words ten words ten words ten words ten words ten words ten words ten words ten words

Why does it require ten words and stuff, can't I just rate the lecture and get over with it?

Very concise and simple explanations. He made it easy to understand.

The lecture breaks it down so simple that it’s easier to understand. There’s still more factors that I’m sure they’ll be discussed in other lectures but it’s perfect to help to create a strong foundation in your knowledge

He speaks very well. Concepts delivered very well. I could understand most of his theory

Concepts are very good and explanation is amazing. I'm in love with it

Great Visualization and the elaborative method of teaching is right according to my mind.

brief , clear, high yield, relaxed, in depth lectures. With a question and answer section at the end of every lecture. I'm loving it

very bad organization of the material vitamin d , then calcium, then vitamin d, then calcium. and there are lots of overlap between classes

Dr Kevin explains the concepts slowly and with emphasis. He also includes the physiological aspects, making biochemistry sound more biological rather than chemical

I loved this lecture ´cause dr ahern was so clear and it really helped me understand this topic.

The professor teaches very well, and difficult concepts are taught in a clear, concise manner.

Basics of this course can be explained in a very detailed manner

man i really find it hard to understand the lectures

The lecture was simple understandable and Clear , it gives a broad explanation about the fundamentals of biochemistry

Amazing Dr. Kevin! Thank you very much for this course!

Made something so complex easy. I've always had trouble here.

the presentation is easy to understand.. it is easier for me to understand the topic im reading in the textbook..

Only wish the section would have also included videos or as link to videos posted elsewhere to Vitamin C, B1,B2,B6 and the rest of the water soluble Vittamins.

I loved this lecture! Everything was so well explained: simple, straightforward, and I especially love few external tidbits thrown in such as the meteorite portion. It helps to remember these facts. Thank you!

This lecture was one of my favorites as it made something so confusing perfectly digestible.

Dr. Ahern is a very good lecturer. He explains concepts very clearly.

This lecture provided me with so much clarity. Thank you

Excellent resource. Thank you. I also enjoy the quizzes and practice medical scenarios.

He explains on a perfect and short way making it easier to understand

Excellent review of the basics; been a practicing Doctor of Chiropractic for 27 years and your videos are bringing it all back again! On the way to taking the MCAT to get my medical doctorate in Pediatric Neurology specializing in neurosurgery. Planning on beginning practice when I am around 68/69...my second career. Thank you for helping me do this great endeavor!!

very good explain in simplest way , I am a physiology student, thanks Dr.

This review, expose the useful tools Anion GAP and Osmolar GAP, it is easy and complete.

Love this lecture. Dr. Ahern explains much better than my professor.

Five-star score not only for the high-yield information but also for the excellent teachers, spaced repetition tests and articles. Thank you all for bringing this amazing learning format!!

They give clear explanations on all topics in such a way that it is easier to grasp. I personally enjoy learning more about a particular topic and Lecturio is the perfect platform to do that as well. I highly recommend Lecturio to all students for better understanding of relevant topics.

Really good explanation. And I like the professor. I understood

Please is important to add more clinical correlation, clinical cases and bridge to other areas: pharmacology, microbiology, etc. Usmle test the integration of knowledge.

Interesting. I have tries to learn this about 2-3 times but never quiet stuck in my mind. Too easy to forget why an enzyme does this or that, however Dr.Kevins way of sharing the WHY this is significant really helped conndct the dots.

Interesting. Mental thirst quenchinly good. Interconnected. Just enough info. Dr.kevin fun lectures.

I honestly had a lot of fun listening to Professor Ahern. You can tell he is really passionate about Biochem. I learned a lot. Great course if you're interested in understanding aspects of the metabolic pathways conceptually while appreciating the details/context that enrich your understanding of them and how they are interrelated.

Beautifully described. Clear and concise presentation. Your all lectures are brilliant

ok. could use improvement please include that Kinesin and Dynein are ATPases that use energy. also that only Kinesin is displayed here. I was so busy looking for Dynein information, that Kinesin info went out the other ear. This could be better by improving the diagram.

This course is an excellent presentation of biochemistry. Professor Ahern presents the material in a clear, concise, easy to understand format that is easy to follow. I really like that I can pick and choose the lectures I need to watch, particularly those that I need to prepare for my upcoming exam. I find the review questions very helpful. Overall, I am finding the course very helpful and I am looking forward to completing more of it.

I love it! It's clear and concise! Dr.Ahern is a gem to learn from. He breaks it down to where I can understand.

Nice speaker and illustrations. The lectures were engaging. Thank you!

Really good divided and explanation, with good examples and great review questions

Comprehensive course with exemplary format & teaching style to explain core concepts.

fast confusing order of explaining Its not like it simlifies anything the way its explained is quite fast and confusing very mono tone

Kevin Ahern is a really good teacher, I really enjoy his lectures, but sometimes it's hard to follow the lecture due to the presentation picturing one thing and him talking about something else. And also when he's talking about about the presentation I wished he had some sort of pointer so I would be easier to know what structure he's talking about????????

Beautiful and very good explanation . easy slides. thankyou. study matter also provided

The presentation is very nice and helpfuly The organization of topics was very good

Concept clearly explained. The professor is very thorough in the description of acid base balance.

I'm impressed with how high yield the information is. The professor touches very important aspects in just the shortest time that one video has, and that is really impressive. I do have a degree in Biochemistry and molecular biology and so this is really making me master the course gradually. For sure I'm recommending this course to my friends from same college already who aspire studying medicine like me.

Great lectures, Dr. Raj! My 8 yr old convinced me to rate before I finished the lecture series.

The videos are shorts and specific an also great explanations

Great explanation with great examples . Knowledgeable in subject matter , content up to date

THE TRANSLATION IS NOT CORRECT, THERE IS NO CONSISTENCY IN THE SENTENCES

Thankyou so much for the opportunity to relearn most of the important and key concepts related to this cornerstone foundation to Medicine & Life Sciences! Wish I had this tool in my undergrad days!!

It was a great lecture, I learn a lot. Thank you Prof. Ahern.

He is the best here , I swear Idk but I like him

Its excellent because there is more physical and clinical correlation and enzyme mechanism simplified

It was informative lecture, the way of explaining the idea and make away to simplify informations was perfect Also putting every information in a clinical scenario was helpful I wish that doctor raj make lectures for all the subjects, his way in explaining is so so special, and he keeps it easier to keep the information for a long term

Great course for introductory level biochemistry. Prof. Kevin Ahen is a great teacher, knowing not only the topic but it's historical background...

I noticed that there weren't any lectures on mineral metabolism in the library. I think students would really appreciate it if you made a module on this topic as it has a lot of biomedical importance and some relevant diseases are associated with it.

He's a legend ooh I don't know what else should I say to complete 10 words

biochemistry was tough as I havent chemistry before. Had to keep reviewing, loved the tests and course presentation and so satisfying when i got the answers right. Great system for people like me . cant wait to do other subjects when i finish this one.

such a hard concept explained so easy and well. such an amazing work sir

what an amazing lecture god bless u sir and i wish to meet u someday

Each and every concept is explained with each lecture it has helped me in getting to know things well rather than just learning.

Thank you so much; Nonetheless, i really need to let you know your vocabulary is above my reach

he is very good, and fun! thankyou doctor carlo raj. best regards, med stud from indonesia

I understand very well, thank you Professor Kevin, these help me a lot

Dr. Ahern pointed out very interesting aspects like heat generation/high energy of PEP and the 2,3-BPG production. Maybe I wasn't paying attention the first time I learned about glycolysis, but this extra integrative information it makes this step easier to remember. Actually, in generally, these human focused biochemistry lectures, are easier to digest, since when I learned it originally, it was mixed with plant and microbial biochem.

It was much needed review for me in general. Thank you.

Enjoyed these videos very much. They helped me understand concepts I was struggling with.

Great work here,,, I’m so happy for the clearly understandable English

The lectures on Enzyme and Enzymes Kinetics were thorough. There were detailed information on some important concepts.

A lot of repetitions which make it perfect to memorize, normal speed of talking - not too fast, not too slow

I just find the need for an extra time revising this, particularly offline. I always find my self making some notes unlike Anatomy!

Prof Ahern explains very well & makes the key steps/enzymes memorable (eg PEP is full of pep!)

So good explications with a nice and simple way . I really appreciate your effort .

I think it’s too fast, and not with details so please correct these problems

Magnificent lecture about polysaccharides and their functions for storage and release

The video highlights the important concepts about the hydrophobic amino acids group

I love the way he explained enzyme.... A brief and easy to understand lecture

Thank you Dr. Kevin Ahern. You made me fall in love with biochemistry.

I really liked the explanation, finally after 2 years, I understand this!! Thanks :)

This guy is awesome!, clear and straight forward. I love the way he motivates me to just keep the important data and let go unnecessary details.

I always enjoyed Dr Ahern's handling of the Biochemistry subject, especially his eplanations

It's is just good that's why 4. I dislike that it's doesn't explain clinical too much

It's okay.... But somehow hard to comprehend. I will love if you can make the teaching much easier to grasp.

Every slide has been clearly explained in detailed form. Thanks sir.

It's unfathomable how much this lecture has saved my time. Though I would appreciate a quick-summary of the products turning into intermediates for other cycles. Like with how g-1-p turns into g-6-p

The lecture simplified glycogenesis to extreme simplicity. It truly helped save around 30 minutes from my lecture, by providing adequate information

very clear explanations and the questions helped me understand the content

It's good, informative not as detailed as I need it to be but it's a good framework to build on

Dr Raj is very wonderful! He made the most difficult topics to look simple and easy to understand. Nice lectures

this video is short and easy to understand. Thanks Teacher

Good explanation. Pretty bad diagram. Animation probably would work better.

Me encantan las clases son muy explicativas y muy detalladas , simplemente excelente!!!

i enjoyed every second of this video and it opened my mind to study more and become what i have always wanted to be a radiologist

I love lecturio, it's the best app in the world. Lecturio has everything you want and can help you to be the best in your class and also be the doctor you want. Lecturio is an opportunity that can give you the change of your student life.

Best lecture. I like the video.I read the slide with this lecture that help me to understand the our lecture.

Concise and clear; exactly what I needed for this topic, thank you.

Good amount of detail in digestable amounts. Very much appreciate able to run the videos at different speeds.

I find Dr .Raj to be energetic, fun and I appreciate him taking the time to teach us concepts and foundations as opposed to blindly memorizing facts. Enjoying his series thoroughly!

No explanation at all just reading , sorry for that , No interaction

It's great to learn from someone who's enthuisiastic about their specialty and even better at teaching it. Thank you Dr. Ahern (:

This lecture is amazing and I loved the explanation regarding the conformational change of hexocinase during the reaction.

I like the short videos. They described what’s important and later you get questions about the video.

I love having access to such rich learning material, thanks for making this an available resource. My only criticism would be that the quiz questions could use improvement and the professor could talk slower to make note taking easier. Overall, very grateful to have found this!

Teacher speak slowly to help me understand Glucose in my body

rate of speech is good and i understanded the subject he explains it very simple

me gusto muchísimo lo recomiendo a todo el mundo que quiera saber mas

Understandable!!! Easy to remember! And pretty useful!!! You really need to learn basics topics in Med career it surely make you to be highlighted over another students

It helped me clarify some topics I had been having trouble with.

Sorry, the following videos have the information that I was looking for, sorry again

I really like the video, makes medical biochemistry easier to understand

I liked the analogy of the gnomes in order to remember what are the causes of acid base disorders.

Excellent, really like the Acid-Base box method and will definitely incorporate that into my exam technique and eventual future practice!

My professors at university failed to explain lipid metabolism in an understandable manner. Prof Ahern does a great job in explaining complex topics and I am really grateful for that. Thank you

I loved it, really interesting and easy to comprehend, thank you very much :)

Need more mcq 's for practice and good content. Very clear concept s

Loved it . High yield and to the point the lecturer was very clear and the quiz at the end of the lectures were very helpful

Very good Thanks Really it doesn't take much time and its really good

the lecrure is detailed and very comprehensive it is well presented i also liked the quiz that comes afer the lecure.

It almost always fails to explain 'why'. These lists are available in any textbook. I was looking for an explanation to understand it. Also, visually it is looking at a table for 5 minutes, pictures could have explained better.

Before Lecturio I struggled with comprehending the mechanism of proteases and enzyme kinetics. Dr. Ahern brilliantly & easily explained these concepts in less than 5 minutes. I am currently in a graduate program for Medical Sciences, we have cumulative exams every quarter & I was just memorizing the info but now I finally understand. I recommend Lecturio to pre-meds, MCAT, and Med students.

I LOVE the lecture but i'm having difficult time understanding it. I had to watch and stop and write to understand it.. maybe more diagrams? or break it down :)

Dear sir/madam In regard to the Biochemistry basics,I am much satisfied by the cours.In fact,the videos concerning biochemitry basics are well summarized and are full of useful information in the regard of médical studies.Because of this,I am enjoying the course and continuing either to learn much more . Yours sincerely Asher Hategekamungu

Dr. Ahern is a fantastic lecturer. All the course is simply awsome.

Dr. Ahern is a fantastic lecturer. All the course is simply awsome.

The course was easy to follow and has good illustrations of the concepts. I also like the quiz portion of the course.

Great professor and easy biochemistry topics to learn with good explanation.

not really engaging, hard to hear and understand. Didn't understand some of what he was saying

It is a good way to learn about Acid-base balance

I work in a large public hospital biochemistry routine department, when I studied this subject there where no computers, only text books. So this is a refresher and update of the subject. I am enjoying this 'new' way of learning and it enhances my work knowledge as understanding theory is important for performing work well.

Whenever I get confused about a pathway, I come to watch these videos and it helps tremendously. Thank you for what you do.

This is completely inadequate for the questions posed. The first question gives "you observed red gnomes outside the box on the left for both pH and HCO3" and asks for the condition. Verbatim from the lecture ‘’Respiratory alkalosis’’. Why? Cos there are two gnomes on one side." Yet the answer is metabolic acidosis.

It was vvvv nice thanks Nicely explained and easy to recall

I always had problems understanding this topic and I always got confused, especially with the last big summarizing diagram. However, this whole lecture helped me to get through it, therefore I can not be thankful enough.

I like his style and respect his effort. I've been using these lecturers to review my knowledge

I find the teaching style to be effective and well planned. I use lecturio for supplimenting the topics taught in my classes

Excellent teaching communicating principles and important details at perfect pace.

Very insightful and brilliant explanation. I learned very much in this lecture! School professor just skip much of the importance in PPP!

hi Biochemistry's videos are interesting and give me information, the orator pronounce correctly. As you know I do my best to prepare ecfmg exam and board examination next, of course after having sufficiently training and advices under your guidance I would like to apply ecfmg examination this year, now would you please give me more information for preparing step one and step 2 exam.

This videos are amazing, the professor is excellent and his explications are clear

He is a very Good Teacher as he teaches as if he was narrating a story.

Brilliant! Dr. Raj focuses on understanding and establishes foundation knowledge for you to build on. Extremely helpful.

The Professor is excellent, every one can understand easily de concepts

Mr. Pickering is a highly professional lecturer. He explains complex definitions quite simply and understandably. It is a great pleasure for me to receive this knowledge from Mr. Pickering

Amazing explanation made me understand the concept clearly in a short time

Excellent teacher . Great lectures . He knows how to teach the subject matter

two stars just for the effort. But its ore like reading fro book. Nothing different. Very boring. No interaction.

Great professor. Has almost everything needed for my course in Biochemistry.

before I read the book but didn't get the concept. This lecture gave me the understanding of this high yield topic.

I was struggling with this subject in school and he explains it so thoroughly.

Talks clearly and explains all the key points so that you can understand the lecture in simple terms

Just on the point, Lecturio is what they say it is. Thank you Lecturio!!!

Studying Biochemistry lectures helps me to understand and hold in memory every each case,,, so this is the best ever

Muy buen docente, se nota que le apasiona su profesion y la ejerce con entusiasmo.

I love it... 100% worth it... Made it simple and easy to understand!

A huge thank you to Prof Ahern! You explanations are very easy to understand and your lectures are a huge help to get a better understanding of biochemistry topics. Thank you very much!

appreciate very the mechanism described in this lecture. Very informative and easy to understand

It’s not a bad lecture but it’s bulky stuff that isn’t simplified to hold ones attention, don’t get me wrong, it has its highlights but it could be more interesting.

Really good discussion. I would love Dr. Ahern to by my mentor

One of the most confusing concept is explained very clearly in a short video!!

All the explanation are precise to the point...and covers all the important concepts

Dr. Ahern creates a great foundation by breaking down concepts and building on them throughout the lectures.

The professor is excellent. I like how he explains things. Some of the professors move their arms around a lot which can be distracting or spend the whole time looking down at the computer. With others it feels like all the do is read from the slides. However the biochem lectures are very well done and by far my favourites so far.

Thank you for your knowledge and for spreading it in this way for us, the students.

The lecturer makes the topic interesting, easy to understand. One begins to appreciate how these things link with everyday human existence and how they play a pivotal role.

its good and thorough, also covers minor lipid types! good to learn

Explains it completely from the start to the end , everything is clear and simple . The structure is very easy to understand.

Dr. Ahern, I appreciate the pharmacological and pathophysiologic connections you make when delivering your lectures. It aids retention and usefulness. I am a nurse practitioner student and can also see the clinical connection. I have administered Methotrexate to many patients. Thank you.

Very high-yield. Thank you for underlining this moment, crucial in treating hypercholesterolemia.

Amazing course. It really makes you understand acid-base balance.

I am a student at Downey High and I really want to be a cardiothoracic surgeon, and I didn't know what to learn but I know this website will help me.

just basic to litle details course.easy to understand it.

A+ teaching style and delivery thank you Dr Ahern for making a difficult topic easier to digest

I think it is an entertaining way to learn the history of Biochemistry.

Excellent lecture. Clear explanation moves step by step with many examples.

Really solid course taking you through the basics of acid base balance and disturbances as well as a great method for figuring out clinical cases with ease. Bravo Dr Wilson for this fantastic set of lectures

I love this guy. The way he explains makes Biochem look easier

I really liked that it gives you the information you need and the way the lecturer explains is very clear and easy way.

He is clear, short, and simplify the most important points

Nicely explained. The Prof. Has exceptional abilities to explain complex concepts

very good and excellent lecture.i like it.very good presentation

he is very clear and is a nice teacher, and he use a appropiated nivel of technicims

Clean and clear. Simple explanations. He knows the subject for sure.

Very first time that I have understood completely acid base balance/ pathology. Beautifully explained!

I really liked this site ,and it's seems helpful for me . I am a high school student. I am in the 10th grade right now. I just want to become a surgeon doctor because I want to save peoples lives. I know that I have to right a commit to this site and I do not have to introduce myself for you people. I do not need to study this because I did not understand today's subject.I just want to be ready for the medical school. I hope this website will help me being ready and ,Good Luck.

I finally understood why we have Lineweaver Burk Plot and how we read it.

The mechanism just summarises all the information into one picture

extremely helpful when the amino acids are divided in functional relevance.

Great lecture. You have a great and enthusiastic way of explaining.

Perfect way of explaining complex things. This is rarely seen by lecturers. Wow!

This lecture was explained super clear and to the point. Thank you!

Attaractively and well explained video of serine protease catalytic mechanism that I have ever seen...Thank you..????

:) Thank you . everything in this lecture is clear. like it very much.

Very eloquent :) my favorite on this website! would definitely recommend.

In my country ( Cambodia ), we don't have USMLE exam but this course helped me to be more understandable and more practical in my career.

Never Understood this concept so easily until Dr. Wilson explained it on this forum.

This is only the first lecture and the first time I am delving into biochemistry for the first time, so hard to say, but something about Prof. Ahern's manner makes me curious and creates a fine feeling of anticipation. Great for a first lecture.

Never understood this much better than today! Thanks a lot for for doing this.

it was described in a simple and easy way to understand, thank you.

This video did not really show Aspartic Acid or Glutamic Acid?

He very easily simplifies things. So this is why I give him a five star review

Amazing, loved it very much. Easy to follow and clear.

amazing ! thank you so much dear dr.Ahern , i was always scared of biochemistry ,but its the first time i finally get to understand it and i owe it all to you. My committee exam will be in two weeks and im hoping to finish this course plus few more lectures from fat metabolism course. also special thanks to lecturio for preparing such a great learning system opportunity for us.

Amazing lectures! Very well explained and effective videos. A perfect way to get a clear view of the subjects, very glad I found this.

Awesome lecture, awesome proffesor. My teacher spent almost 1 hour explaining that. Thank you Dr. Ahern

as a beginer i didnt couldn't understand anything the lecturer is talking about and the lecturer is way too fast

I'll just say thank you very very very very much!!!

Thorough and patient presentation of an often problematic topic to a lot of students and practising physicians

My name is Barbara, I'm from Colombia and I really like your videos Mr. Kevin, because I think the content is easy to understand.

Vitamin section is fine, concerned vitamins explained clearly and easily However, some water soluble vitamins are considered missing (eg. thiamine, riboflavin, biotin, vitamin C ) although they might be encountered in some other subjects; such as nutrition. Additionally, minerals are not touched in these lecture series at all Overall, it is a very good course for the material targeted, but needs to fill the gap of missing items

Pure gold indeed !!! Presentation of chemical compounds during presentations is very helpful.

Love him so far, clear concise and to the point and also very enlightening

it is a very interesting materail, so clear an usefull and could recomend it without any question

Yea, these lessons site wide need more quiz questions. Only thing holding this site back from being outstanding.

Very well explained and detailed lecture, but it would be nice for better understanding to have some names and terms (e.g. Ramachandran plot) displayed in the video!

way too fast ????I really wish the teacher would talk slower as now I keep having to pause and rewind etc.

Direct , and easy to follow. The length of the video also helps.

Great professor but unfortunately the details of this lecture are not important for USMLE Step 1

Easy to understand and the explanation are very clear. Thank you very much good job!

THANK YOU Pro Ahern you're amazing! very well explained!

Professor Ahern is a perfect teacher and he makes everything so easy to understand

Needs more details, and take it slower so that we the audience can get a more thorough understanding of the topic (the video really doesnt need to be that short)

Dr. Wilson, you are my hero, you made this concept of acid base balance so easy for the first time in my life. Thank you so much!!

I found it really helpful. Your explanations were clear and easy to understand.

Brilliant lectures, really helped to consolidate my learning. The associated test questions are a pain in the ass though, please supply a reference range with the question... we use different ranges (units) over this side of the pond :0)

Thank you for the video's theses are really helpful. look forward to keep learning.

very nice clear and organized lecture. thank you. it adds alot to my simple knowledge

thanks for teaching me in such a clear, precise, and yet enriching way

It explains the most important aspects of acid-base disorders and gives good examples for us to understand the concepts. I personally liked his explanations very much.

excellent lecture. Cristal clear; not too slow not too fast, smooth transitions and a bright ending

It was very precise and up to the point. The presentation was interesting that triggers to study better .

very good lecture. pretty well organized and instructive. He has a deep knowledge of the material making me to pay special attention to all his lectures.

Very nice and informative lecture, easy to understand and remember

I have followed Dr Ahern through all the basics of biochem lectures and he has never failed to deliver.

Great job again Dr. Ahern! You have helped me better my understanding of these topics.

Great job, Dr. Ahern. Thank you for bettering my understanding of these concepts! Used as a supplement to lectures and powerpoints, your videos on Lecturio have been extremely helpful to me!

Very good lecture, l consider that is one of the most complete themes that l´ve read ...good job.

very informative and well explained lecture. Dr. Kevin Ahern has changed my view of biochemistry.

Very well put. Dr Kevin Ahern explains difficult topics in a very short concise and interesting manner.

This entire series is the most eloquent and beautiful explanation of a terrible terrible subject like biochemistry I have ever seen to attended

Its a little bit dificult to understand but the information its complete and tables and graphics helps a lot

Conveyed the process in a short &digestable way.I LIKED THE WAY OF presentation too.

Had so much difficulty learning the enzymes on the pathways. This way was easy to understand it!!

his teaching is clear and it is not allowing me to get even a single doubt

i could understand the concepts better. explanation was good.the charts were self explanatory. it made me feel bio chem much more interesting.

the acid base balance section was great. clear, precise and the acid base box just made it all click. Fantastic!

His fluid, conversational presentation style really makes it stick. I do not want my classmates to know about him.

I like the way you link things from one to another. Yuu made these lectures highly appreciated with the concise and comprehensive explanation! Thanks Prof!

really helpful i never found this data in any of my textbooks

Not my favorite subject but very well explained and understanded.

Wonderful! An awesome lecturer, he just has a unique way of passing the message. Great work Sir

He explains it very well and at a good speed. He doesn't use to many difficult words so if your first language isn't english it's still possible to understand. Also whenever you have a question he answers quickly en thouroughly.

It is really helpful. I appreciate your kind efforts. Thanks verh much.

i like your teaching .sir. it helps me to understand the concepts clearly.

Excellent information and explanation, it's helping me a lot. Congrats, lecturio!

Great lecturer very knowledgeable of subject matter at an admirable pace. Needed this in depth type of lecture in med sch. This guy is just good.... Great job

Great lecturer very knowledgeable of subject matter at an admirable pace. Needed this in depth type of lecture in med sch. Good job

Great lecturer very knowledgeable of subject matter at an admirable pace. Good job

It was just amazing, he was critic to give information and had the most important skills for me, and that is: perfect didactic. Had all concise information I needed.

He simplified the concepts and illustrated by a very nice way

Excellent delivery of content which was easy to understand Good use of diagrams and graphs to help explain key concepts

This lecture helps me a lot since i jave a hard time to understand.

High yield facts and clear explanation, the fundamental elements and efficient route to master biochem!

I am new to this curriculum, however, I would like the lectures to be longer. I am hopeful that other lectures are much more detailed, e.g. gene regulation/expression. Lecturer is very knowledgeable, clearly.

I liked very much this course. It's very interesting and The good teachers.

I liked the lecture and the diagrams, I can put 5 stars yet because I am unsure how relevant everything is. Pretty basic biochem, but it was a good refresher. The diagrams are helpful.

Cool. Great examples, Should have showed how the equilibrium of the equation changes once there's acid base disturbance, and how does the compensation is predicted. For me it's much easier than the graphs.

The material covered a wide variety and having a non-science background it is clear and easy to understand.

This guy just knows his stuff, on point even with the speed of his speech he has mastered his slides. I almost got scared with the previous lecture in genetics but he managed to bring me back home. Very knowledgeable keep up the good work and add more clinical correlations.

Liked but another lecture not opened yet so not liked

It was simply amazing. The knowledge I got exposed to was simply clear cut and delivered by an expert in layman's literature. I am keen to absorb more of Mr. Kevin Ahern's lectures.

I like how Dr. Ahern took his time to explain the topic in an articulate manner. Helped me understand the topic and want to learn it more.

El semestre pasado apenas y me di cuenta de todo lo que la enzimas y las reacciones significaban, ahora creo tener una visión mucho ma completa, GRACIAS

Batalle mucho para entnder mis clases pero con estén curso tengo un mejor dominio de el metabolismo y me permitió realizar una presentacion del tema ????

Very easily to follow. The concepts are explained so that one who isn’t familiar with biochem can understand with ease.

How I wish I had this when I first started medical school. The explanations were clear and concise. The use of simple words enable me to understand it well as well as the option to pause at anytime allows further internalization of the facts.

Recommend this course to any medical students doing pre/clinical Helps with pathways and understanding breakdown.

Helped me a lot understanding this subject! Carlo Raj's videos har really good.

You can memorize or you can understand. Concepts are yours forever. Memorized lists of facts are gone the very next time you need to cram for another test.

I never would've thought such a complex respiratory concept would be simplified by a bunch of colored garden gnomes. Thanks Dr. Wilson!

Excellent! Well delivered and full of quality information. Totally recommend this course.

Doctor Ahren. Great explanations and enhances my knowledge in biochemistry, i´d rather reccomend you tu use a lower velocity on your explanations because some of the students are foreigners and they probably may lose the idea. Nevertheless i´m completely satisfied with your video lectures.

Simplified the lecture in enzymes and i like how everything was explained in a simple but direct way. :)

I finally understood why keto diet is so effective :) Thank you Dr. Kevin!

This was a good course because the lecturer gave examples and explanations.

Very good explanation of concepts. Animation could be added for excellent explanation.

Very informative and organized , keep the good work Thank you

it's amazing the example with the gnoms thank you !! easy to learn

The lecture was very intriguing! Dr. Ahern is so well articulated!

This is about the best lectures I have had all my life. I like it very much because the lectures are very explicit, The approach is fantastic. And the tutors are very experienced. They have a full grab of the subjects they teach. The team is like a conglomerate of experts from all fields of medical science. It has really helped in my studies in medical school. With Lecturio, there's no dull moment. It's actually a huge privilege for those of us studying Medicine and Surgery in Africa. I recommend Lecturio for everyone who want to excel in medical practice all over the world! Kudos to all the erudite tutors in the house! Hope to see more of you in Lecturio videos. You're all wonderful! From: APATA OLABANJI SYLVESTER COLLEGE OF MEDICINE UNIVERSITY OF LAGOS, LAGOS, NIGERIA. WEST AFRICA. (e-mail: olabanjiapata@yahoo.com)

The Good: Lecture: 5/5 Amazing Lecture! I learned a lot! The Not so good: Quiz:2/5 Only 1 question....and was not as specific as I would like it to have been. Perhaps consider having at least 50% of the terms discussed included in the Quiz.

The subject is really hard... but the professor is excellent!

Wow! Never thought I’d be amazed by the clarity and succintness of the discussion. Packs into a few minutes what would take a four hour lecture to discuss. Defintely recommended these lectures to my friends who are struggling with biochemistry and don’t want to use the books so much.

the lecture is good it educates on how bichemistry is related to other fields in life

thank you very much doctor kevinm very helpful lectures, especially vitamin D.

I understand, but I think, the lesson needs drawings and diagrams, but is very well, thanks

Thank you Dr Ahern! Thanks to your clear and nice explanations With integrations I am finally starting to understand Biochem! You make difficult things look so simple and enhances the importance and intelligence of mother nature in our human bodies

Incredibly good! I have spent hours studying from the book and this is by far the most helpful in terms of deep,meaningful understanding of the subject.

The courses are very concisely presented, it is really useful for preping for an exam

Need more details Need to go slower But overall not bad

It is very clearly and enthusiastically explained. You make Biochem easy to understand.

As a medical student I found this series of lectures on enzymes extremely clarifying. Dr Ahern is a great lecturer. Thank you so much.

The lecturer is very good at getting biochemistry across. Well explained and understandable up and until here.

Professor Dr. Kevin Ahern is very clear in presenting. Love the short but very informative lectures. Would recommend to everyone, those with or without biochemistry understanding. Thank you very much Professor and Thanks to the maker of Lecturio.

Kevin must be the best teacher ever. He explains with a certainty only a person with many years of lecturing can. Simple, easy and fast, making complicated matters seem easy to learn. Compared to the slides i have in med. school, the content is the same. But this guy also gives the explaination in the same amount of time! His body language is also nice to watch as they are firm and open, kind of directing your thoughts, like a maestro. You just have to remember and do some repetition of EVERY detail he mentiones, it will for sure be on the exam. I also use his lectures to simplify my understandings from pdf files from school and heavy textbooks. I will recommend everyone to use this!! Also i love the quiz afterwards. 1rst year university medicine

Very clear summary. Would like to see more clinical correlations made.

Everything was on point .. Will definitely share with my friends.

I understood perfectly the concepts the way he explained them. He makes it ease to grasp

Very simple and easy to understand. Would definitely recommend this course.

Very concisely put, I love the lectures, very helpful indeed. Now all I need to do is work my ass off to get the dollars to pay for this awesome lecture. Thank you Lecturio!

I found the lectures to be very informative and composed of high-yield information for a relatively quick review of the subject. The only reason I give 4* is because of the few technical problems with the course; but, in regard to the course material, Lecturio provides a wonderful review of Biochemistry with Dr. Ahern.

It is really so good thing to take more information and I like so much the way of the explain for the teacher thank you so much for this helping for students

I love to use this great app to review my med knowledge!

I like the way that the AA are presented by a table between essentiel and non essential. I will use it for my memorizing process.

Great/clear explanation, definitely recommend to students. For those that complained, please describe what's needed to be explained, or just keep your pie hole closed. Being ambiguous is pointless.

no words can describe how much this was amazingly useful

I like the teaching style and material presented! It is clear and understandable. Thank you!

l am a pre-med student and after watching this lecture I decided I was definitely subscribing! Everything was explained clearly and I understood the concept completely.

The use of the acid-base box made this topic so easy Thanks

It needs more clinical correlation with diseases in the IV fluids For example, when to use normal saline or when to use dextrose this will make our understanding better

Explained easily and good diagrams. Good at pointing out key concepts.

Kevin Ahren explained the part very well. I liked the way he explaining this part. I am from business back ground.

Both comprehensive and simple lectures, could use some more medical/clinical correlations, though.

i like this lecture. way of representing and explaining is quiet good.

Finally understood the anion gap!! Thank you! The chart with the green red and blue midgets I found very funny and creative and even if I took this course several months ago, I still remember perfectly the chart because of them!

It is fantastic to have a lecturer making a diffucult subject easy. Now i can not wait diving into some hardcore books about enzymes. Watching an inspiring teacher really makes a difference. This guy is also rather fast talking so you dont need to speed up, witch i do quite often. Also the pop quiz in the end just makes it so much more fun. It becomes a game. And thats great and enhances long term memory.

great great lecture!! thank you so much Dr. Raj :) one of the best lecture i have ever watched.. you made learning so much fun :)

Very nice but there's some need of detailed explanation and then it would be perfect

On the slide about respiratory compensation for metabolic acidosis, the compensation slope with decrease Pco2 level has a PCO2 value of 60 which should be 20. Becauase in respiratory Compensation for MA PCO2 slightly decreases That is just a typo, but can been confusing The lecture itself is very good

Easy to understand with the structure of the molecule. Very clear and straight forward.

Awesome job, I wish you were my teacher at my university! So clear!

I subscribe because of this professor. Great lectures and explanation. Nice job

It had been a few years since reviewing enzyme kinematics, this was a great refresher!

I loved the whole course! I finally could understand a topic that is so frustrating for me to understand and also remember in time! Dr Tad is an awesome lecturer! I lo ve the way he explains everything

The material as presented is easy to follow and comprehend

thank you very much, nice lecture, sounds great, well presented

it´s great conference, well explain, clear and simple. like ir a lot

very good course, i wish i have money to pay the all course

The facilitators are very good because they motivate you to learn.

thanks. the lecture was very informative and concise for such a complicated topic

the plot charts are really confusing. takes a few replays to grasp a little.

Lecturer seems to know the material and is able to convey in a manner that is engaging

These lectures are made simple for someone like me who is very vulnerable to biochemistry.

Easy to learn using the box. I always struggled with this, even on my board exam. This box and explanation made it much easier for me as a visual learner.

I found this course to be very helpful to organize my knowledge about this topic. It also clarified to me some concepts that I had not fully understood in lectures.

As it's my first lecture, I think I have to work a lot for getting great benefits from your great tutors. hence I had to give this rate. right now there are no such dislikes. well, thanks a lot for the kind assistance.

These lessons are brilliant enjoyed them so much I have bought some books by Kevin Ahern, PhD the questions at the end also reinforce learning.

Great lecturers and thorough explanations for every subject. After watching the lectures, I actually understood and retained because his lectures are extremely well organized.

This is quite helpful. I am a pre-Medical student and I'm fully satisfied by the leacture. I'm able to cover all the syllabus. It's helping me to save time. I dont need all those notes n stuffs. Most important i can practise lots of questions! I'll recommend all Medical students to take this amazing leacture for once so that you'll be able to understand. Thankyou @lecturio! ????

Good lecturer, though compared to common youtube lectures, most of the material is covered too superficially to really retain much, although the gnome chart was helpful for myself. Future lectures could give just a bit more detail to help the bigger picture ideas stick.

Great professor, great explanations. This video was like a summary of important parts.

A ERY INTERESTING COURSE ,BUT REQIURES A LLOT OF STUDY TIME TO UNDERSTAND THE AMINO ACID CHEMISTRY. TO BE HONEST, I AM A RETIRED 85 YR OLD PHARMACIST TREYING TOEEP UP.

I really like the pace and clarity of this lecturer in how he presents the material. It would be nice to have animated pictures in signaling and transport. I also wish there were sections covering enzymatic catalysis & kinetics. Over all, very good! Thank you for making these

blue ,red gnomes ,suoer ,really good lecture,clarified,simplified,nice

Exactly what I needed. Straightforward and to the point. Linearly organized.

Very helpful Keep it up .. easy to understand . Lecture in a simple way

Hello though I learnt new things by the good explanation of the pathway but I will be happy if there could be mnemonics to remember then easily. Thanks

The acid base box helped me alot and the lecturer is brilliant

I rate this five stars because I like to go over it while I do other things and more than once.

The overview of biochemistry is really helpful! The images are great, and the lecture is really high quality.

it is a good course. easy to understand. I liked this course

I was hoping for a little more details about the chemical makeup of the topic, however, I like how the entire video is layed out and described.

This is professor is really good at explaining concepts and is thorough with getting caught up in the details

Dr. Wilson does an excellent job in breaking down concepts of acid-base balance in the body and making it plain. He also provides some additional tricks/tools that you may not get in your regular lectures, but will definitely help on an exam. These lectures are top notch, just excellent!

A very clear understanding of the basic concepts was developed by Kevin. Good examples and perfect illustrations made everything so easy and interesting.

Watching these videos from Lecturio is very much like being in my school. The difference is Lecturio is more fun and it encourages us every time we want.

very clear Explanation; I managed to understand mechanism for each type of Ihnibitors thus I can now draw the lineweaver plots.

Great constructive instruction at a understandable medical level thank you! Thelma Boshoff

With this introductory course, you will be exposed to the basic aspects of Biochemistry. Professor Ahern emphasizes that an in-depth knowledge of basic biochemistry will aid you tremendously in understanding life processes on a macroscopic level. This one course alone was well worth the one month payment of 24$. Every other course on top of that was an attractive but inessential addition..."icing on the cake"!

Very good explnation ! very easy to understand. I like Acide-Base toolbox. Many thanks :)

Professor Ahern is truly excellent! Amazing choice. He clearly explains concepts and shows sincere enthusiasm for the topics. You need to bring him back for lectures on amino acids and the urea cycle as well as the electron transport chain.

Very easy to follow, good flow and simply explained, exceptional professor! just wish the questions had explanations then I would give the videos a higher score .

it has helped me build my understanding of biochemistry. looking forward to more lectures

Love this course and Professor Ahern's enthusiasm keeps my attention. Being able to watch the videos over and over helps the lessons sink in. For the first time I'm enjoying biochemistry. Thank you for making these videos so affordable and easy to use.

Accurate, slow enough to understand, and he gives concrete examples that clarify each concept. Keep it coming.

Since is starting this biochemistry, it's help me to remember some of the basic concepts that I have forgotten

This is an amazing course! Prof Kevin has made every single details simple and clear. His deep knowledge and understanding of this subject is well reflected in his teaching style. The materials he used, are very attractive which makes it easy to memorize. I would definetly recommend this for both under and postgradustes students.

This course is well done. It's thorough. I'm reviewing things I've learned, and also moving on to more advanced material very soon. I wish I would have had this during undergrad.

The biochemiThe biochemistry is one of the best because the professor Ahern is a terrific docent who makes one love the lectures
