Organic Chemistry 51C. Lecture 17. More Structure, Stereochemistry, & Reactions of Carbohydrates.

>>Good morning.>>Good morning.>>So, today I’d like to continue our discussion of the structure and stereochemistry of sugars. We’re going to then talk about reactions of sugars. And we’re going to come back at the end to look, everything works out, how Emil Fischer originally determined the structure and stereochemistry of sugars in what really was […]

Carbohydrates – absolute configuration, epimers, common names | MCAT | Khan Academy

– Okay, so we spend a lot of time on the front end of carbohydrates, talking about their stereochemistry, especially of that last chiral center. And again, it’s because it plays a large role in the biological function of these molecules. For example, we humans are enzymatically programmed to break down and digest the D-sugars. […]

Carbohydrates – cyclic structures and anomers | Chemical processes | MCAT | Khan Academy

– Alrightie, so we’ve been speaking so far about carbohydrates as chains of carbon atoms. And these are chains of carbon atoms that feature an aldehyde or a ketone functional group. And that falls into this general kinda one-to-two-to-one ratio of carbon, hydrogen, and oxygen. And of course I’ll keep using glucose as an example. […]

Carbohydrates – naming and classification | Chemical processes | MCAT | Khan Academy

– [Voiceover] The term ‘carbohydrate’ refers to a chemical compound made up of carbon atoms that are fully hydrated. So ‘carbo’, for carbon, and ‘hydrate’, for hydration or water. And because these biological molecules are hydrates of carbon, you can find them fitting into the general formula; C, so a number of carbon atoms, n […]

Carbohydrates Part 1: Simple Sugars and Fischer Projections

Hey it’s professor Dave, let’s talk about carbohydrates. We’ve all heard of carbohydrates and sugars, especially if we are loading up with energy for the big game, or if we’re on a diet. But many people don’t know that these words refer to the same class of molecules. Carbohydrates got their name because they are […]

Organic Chemistry 51C. Lecture 16. Introduction to Carbohydrates: Structure and Stereochemistry.

>>All right, give yourselves a big hand. We’ve done five quizzes in the class. We’ve got one last one to go, which is sort of a bonus in the sense that I drop the lowest quiz. We’ve also gone through what I consider to be some of the most intellectually challenging material of the course. […]
