Organic Chemistry: 7 Must-Know Reactions of Alkenes

Hi everyone this is Maverick Puah the Chemistry Guru now in this video we want to run through the 7 must-know reactions of alkenes, so let’s take a look now the first must-know reaction is hydrogenation of alkene to alkane so the reagents and conditions will be H2 (g) in platinium catalyst, heat second must-know […]

Organic Chemistry Functional Groups – How to Understand and Memorize Functional Groups

Leah here from leah4sci.com and in this video we’ll take a look at common functional groups that you have to know in your Organic Chemistry course. Be sure to check out my functional group quiz and cheat sheet as well as the videos on how to name each particular group by visiting my website leah4sci.com/Naming. […]

Acetal and Hemiacetal Formation Reaction Mechanism From Aldehydes and Ketones

Leah here from Leah4sci.com and this video were going to look at the reaction mechanism for actetals, hemiacetals, ketals and hemiketals In the last video we introduced the acetal and ketal concept along with the trick and shortcut to help you easily identify reactants and products. A few things before we look at the mechanism, […]

Alpha/beta Mixed Domains

The most common and regular of the protein domains are protein domains that consist of both α helices and β strands. And these are known as α-β domains. Following along a peptide sequence that is part of an α-β domain what you would find is that it’s alternating between a β strand ah that’s connected […]

Introduction to the Shikimate Pathway

The organic chemistry that you’ve learned over the last year gives you the foundation to understand molecular level detail of virtually any biological process that we know about today. I want to illustrate this to you in the next five webcasts by looking in great detail at one particular biosynthetic pathway; it’s called the shikimate […]

Natural vs. Synthetic Vitamins

hey everyone its professor Dave, I wanna talk to you about natural versus synthetic vitamins vitamins nature makes them and humans make them in the lab. are they the same? surely natural is better and synthetic is a cheap imitation right? it’s tempting to think this way because of analogies we can make in the […]

Nucleosides, Nucleotides & Nucleic Acids

In his book, “What Mad Pursuit,” Francis Crick does an excellent job capturing the essence of what has been our focus in CHEM 332. The idea that without understanding molecules, we cannot understand life itself. We want to carry this theme forward in our final section on nucleic acids. Where we want to understand the […]

Serine & Cysteine Proteases

Suppose you just identified that there’s a serine protease as an important biological target for therapeutic applications that needs to be inhibited. The first thing you’d want to do, and what we’re gonna do in this webcast, is understand the molecular mechanism of the normal mode of action of that enzyme. And for serine proteases, […]

Application of General Acid/General Base Catalysis

I hope you had a chance to look at this problem. It’s an excellent example that illustrates how a general acid and a general base can work together to carry out some reactions like nucleophile addition to a polarized π bond or β elimination. What we want to do in each step is to use […]

Hydrocarbon Derivatives: Crash Course Chemistry #43

The smell of cinnamon and rotting cadavers… Compounds that can remove nail polish, power a car, knock you unconscious, or make your headache go away. All of these things can be accomplished by simple organic compounds with different functional groups sticking off of them! Yes, I said functional groups! We will be talking about them […]
