A Level Biology: Amino Acid Structure

hey guys welcome back to learnbiology.net I’m Frankie and in this revision session we’re going to cover the specification reference three point one point four point one this is topic 1a and your learning outcomes are number one know the general structure of an amino acid and understand that amino acids are the monomers from […]

Pentose Phosphate Enzymes, ATP, and B Vitamins | Masterclass With Masterjohn 1.11

Hi. I’m Dr. Chris Masterjohn of chrismasterjohnphd.com, and you are watching Masterclass with Masterjohn. And today we’re in our eleventh in a series of lessons on the antioxidant defense system. In the last lesson we talked about how the pentose phosphate pathway is what produces NADPH. And NADPH is an energy carrier that is derived […]

LDL and VLDL Metabolism: Lipoprotein metabolism: Endogenous pathway of lipid transport

Hi, this is Dr. Vijay. Today we are going to study LDL and VLDL metabolism. So, this LDL and VLDL metabolism is the transport of lipids between liver and extrahepatic tissues and this pathway is also known as the endogenous pathway. Perhaps liver has the capacity to synthesize various lipids and they are packaged in […]

#07 Biochemistry Protein Characterization Lecture for Kevin Ahern’s BB 450/550

Another Monday beckons, another week beckons. One day closer to an exam. Student: Whoo! Kevin Ahern: Yay, huh? One day closer to your opportunity to show me how much you know. That’s good. I hope you had a good weekend. Student: Fantastic. Kevin Ahern: Fantastic? Student: We won. Kevin Ahern: Are we talking about football […]

20.03 Rate Enhancement by Proximity & Orientation

In this webcast what we want to do is take a look at the ways that enzymes bring about stability of the transition state relative to the substrate. There’s basically two most important factors, one is known as proximity, also sometimes called effective molarity, and the second factor is known as orientation effects. Let’s take […]

Introduction to Biochemistry

Hey, it’s professor Dave, let’s talk about biochemistry. What is biochemistry? Is it biology? Is it chemistry? Well as you might guess, it’s sort of in-between, quite literally in terms of size. In the great panoply of the sciences, biochemistry sits right here. If we go smaller we get into small molecules made of just […]

HDL Metabolism: Reverse cholesterol transport

Hi, this is Dr. Vijay. Today we are going to study high density lipoprotein metabolism or HDL metabolism. So, before watching this video, you should know some of the basics, for that please watch this video, that is under lipid chemistry playlist where I have explained basics about lipoproteins, like what are the different classes […]

Pantothenic Acid, Part 2 (Testing, Food, and Supplements) | Mastering Nutrition #66

I’m dr. Chris master John of Chris master John PhD comm and I’m here with Alex leaf Hey and you are listening to episode 66 of mastering nutrition where we talk about pantothenic acid part 2 foods lab tests and supplements this is a spring nutrition with Chris master job take control of your health […]

Suicide Enzyme Inhibition

Hi, this is Dr. Vijay. Today we are going to study suicide enzyme inhibition. So, this suicide enzyme inhibition is irreversible inhibition. Here the inhibitor molecules or you can say the modified substrates, they are actually looks similar to substrates. They are substrate analogs, their structure is almost similar to the substrate just like competitive […]

Uncompetitive Enzyme Inhibition

Hello everyone, welcome back, this is Dr. Vijay. Today we’re going to study about uncompetitive enzyme inhibition. Uncompetitive enzyme inhibition means inhibitor molecule binds to only enzyme substrate complex. Unlike competitive and noncompetitive enzyme inhibitors, this uncompetitive enzyme inhibitor only binds to after formation of enzyme substrate complex, that is why this is called uncompetitive, […]
