Lignin Staining – Amrita University

Lignin Staining Lignin, a complex phenylpropanoid polymer, is primarily deposited in the walls of cells that have secondary wall thickening, such as tracheary elements and fibers. Lignin provides mechanical strength to the walls of these sclerenchyma cells. Lignin is derived from the de-hydrogenative polymerization of the monolignols p-coumaryl alcohol, coniferyl alcohol, and sinapyl alcohol. These […]

Carbohydrates Part 2: Polysaccharides

Hey guys, it’s professor Dave. Let’s discuss polysaccharides. Carbohydrates include simple sugars like monosaccharides, but they also include polysaccharides, which are long polymers of these simple sugars, so we need to understand the way they polymerize, as well as certain characteristics of the resulting polymers. First let’s return to our Haworth projection for beta-glucose. In […]

Carbohydrates- di and polysaccharides | Chemical processes | MCAT | Khan Academy

– Alright, so in a previous video I talked about how cyclic Monosaccharides like this green cyclic Glucose can react with Alcohols, like this pink Alcohol, to form Acetals and Ketals. And I believe that I mentioned that sometimes the Alcohol comes in and is reduced, is actually another Carbohydrate. So let me kind of […]

#17 Biochemistry Carbohydrates II Lecture for Kevin Ahern’s BB 450/550

Kevin Ahern: Should we just call off class today? What do you think? Student: Yeah! Kevin Ahern: And then go twice as fast on Monday? [laughter] Until we get to Monday, right? I’m going to get through party pretty much carbohydrates today. I’m not sure if I’ll finish it completely, but if I do, great. […]

Ahern’s BB 350 at OSU – 25. Carbohydrates & Energy

Almost Friday, Friday for this class almost? Hello? All right, I have a lot of ground to cover, so let’s get into it. Yesterday, I introduced the topic of carbohydrates, particularly from a perspective of structure and nomenclature. And while I will show you a little bit more today about nomenclature and a little bit […]

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. […]
