Errors in the Video
von Peddi A. am 12. Oktober 2023 für Saccharides – Simple Carbohydrates
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.
teaching method is boring and not helpful for my mind to understand
von Enarah R. am 04. Dezember 2022 für Pathway Overview and Reactions – Part 1
not explned wel as the topic is difficult and you made it a lot much boring
Perfect
von Selma u. am 07. September 2022 für Disorders of Carbohydrate Metabolism
Excellent lecture, very clear and well explained. Thank you so much!
Thank you
von Johnson O. am 13. Juli 2022 für Gluconeogenesis: Metabolism of Galactose
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.

Amazing Dr. Kevin!
Thank you very much for this course!
Excellent lecture
von Jalil Z. am 15. Februar 2021 für Disorders of Carbohydrate Metabolism
Excellent lecture. This is a difficult topic and it was made very clear, especially the mnemonics.
Delivers needed information about metabolism of Galactose
von Mohammed A. am 22. Oktober 2020 für Gluconeogenesis: Metabolism of Galactose
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
Essential lecture materials
von Lisa R. am 25. August 2020 für Common Sugars: Nomenclature & Structure – Simple Carbohydrates
Concise and clear; exactly what I needed for this topic, thank you.
Love, love, love Dr. Ahern's videos
von Joslyn D. am 01. April 2020 für Glycolysis: F1,6P –> DHAP – Glycolysis and Pyruvate Metabolism
Whenever I get confused about a pathway, I come to watch these videos and it helps tremendously. Thank you for what you do.
Very clear lecture
von Haichuan H. am 01. April 2020 für Disorders of Carbohydrate Metabolism
Very clear lecture right on points. Thank you for making complicated concepts straight forward.
Best biochemistry course
von ? 懷. am 29. Januar 2020 für Pathway Overview and Reactions – Part 2
Very insightful and brilliant explanation. I learned very much in this lecture! School professor just skip much of the importance in PPP!
Excellent
von Sandrine D. am 12. Januar 2020 für Glycolysis: F1,6P –> DHAP – Glycolysis and Pyruvate Metabolism
He is a very Good Teacher as he teaches as if he was narrating a story.
Great teacher, rate
von rouzbeh t. am 25. November 2018 für Glycolysis: F1,6P –> DHAP – Glycolysis and Pyruvate Metabolism
Love him so far, clear concise and to the point and also very enlightening
Thank you! Better than any of my teachers at my university!
von Sara P. am 20. Juli 2017 für Saccharides – Simple Carbohydrates
Awesome job, I wish you were my teacher at my university! So clear!
Very Good Professor.
von Eda D. am 02. März 2017 für Pathway Overview and Reactions – Part 1
Great professor, great explanations. This video was like a summary of important parts.
