Lectures (PUMS MD Medical Chemistry)

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

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.

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.

Recomendo pra todos que querem saber melhor sob Medina das universidades

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

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

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

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.

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.

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

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

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.

This lecture provided me with so much clarity. Thank you

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

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

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.

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

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

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

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

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

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

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 :)

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

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

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.

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

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

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

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.

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

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

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

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!!!

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

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

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

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.

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

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

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

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

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

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

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

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.

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.

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

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

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

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

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.

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

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

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. 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.

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.

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

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

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

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.

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!

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.

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.

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

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.

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

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.

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!

no words can describe how much this was amazingly useful

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.

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.

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.

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

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

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

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

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

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

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

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

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

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
