Carbohydrates – BioChemistry – NEET Preparation by NEETLab

Welcome to Neetlab. A free online self learning platform to improve your intelligence and to clear NEET examination our topic is about Carbohydrates We have already seen in the previous video about the introduction of carbohydrates , Now lets see in detail about carbohydrates Carbohydrate is a bio molecule compound containing carbon, hydrogen and oxygen […]

Carbohydrates and Lipids: Key Biomolecules I

Hi, everybody. This screencast is going to discuss biomolecules. We’re going to do an overview as well as talk about carbohydrates and lipids. So, in one of our last screencasts we talked about different kinds of atoms that are very commonly combined together in biology; those are carbon, hydrogen, oxygen nitrogen, phosphorus and sulfur. And […]

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 […]

Macromolecules: Lipids, Carbohydrates, Nucleic Acid, Excerpt 1 | MIT 7.01SC Fundamentals of Biology

HAZEL SIVE: Another truism of biochemistry is that many of the molecules within cells are very large. And they’re called macromolecules, to indicate this. So macromolecules. So these are often — Biological molecules are often macromolecules. And these macromolecules are often polymers– not always– where a polymer is some kind of repeat of a monomer […]

Photosynthesis: Crash Course Biology #8

Photosynthesis! It is not some kind of abstract scientific thing. You would be dead without plants and their magical- nay, SCIENTIFIC ability to convert sunlight, carbon dioxide and water into glucose and pure, delicious oxygen. This happens exclusively through photosynthesis, a process that was developed 450 million years ago and actually rather sucks. It’s complicated, […]

Biological Molecules – You Are What You Eat: Crash Course Biology #3

Hello, and welcome to the kitchen. I wanted to invite you here today because last week we started off in my bathroom and kinda feel bad about that. And also because as I’m making lunch today I wanted to sort of use it as a lab. During this time in my kitchen I’m going to […]
