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 […]

Protein Sythesis

Welcome to Protein Synthesis. In this video, you’ll explore what protein synthesis is including the two parts of its process: transcription and translation. Protein synthesis means making protein. Whenever cells want to make any type of protein, they use a process that includes building blocks like amino acids, to build new proteins inside of the […]

Protein Synthesis [HD Animation]

in prokaryotic cells translation is initiated by formation of an initiation complex consisting of the 30s ribosomal subunit formal methanol tRNA and messenger RNA the 50s ribosomal subunit then joins the complex proteins called initiation factors are also involved but are not shown the 70s ribosome has two sides to which transfer RNA carrying amino […]

Common Types of Chemical Reactions

Leah here from leah4sci.com/MCAT and in this video we’re going to look at different types of chemical reactions. You’ll see many types of chemical reactions on the MCAT and even though you won’t be tested for them directly, you still want to know what the reaction is and how to recognize them because this will […]

#47 Biochemistry Transcription III / Translation I Lecture for Kevin Ahern’s BB 451/551

Kevin Ahern: Happy Friday. Very good, very good. I have you trained. Happy weekend. No exam this coming week [class cheers] Finals beckon… Okay, so we’re moving along talking about transcription. Last time I got started talking a little bit about eukaryotic transcription. I’m going to say a lot more about that today, and a […]

#48 Biochemistry Translation II Lecture for Kevin Ahern’s BB 451/551

Captioning provided by Disability Access Services at Oregon State University. [class murmuring] Kevin Ahern: Okay folks, let’s get started! Happy Monday. Nobody’s ever happy on Monday. I am. Student: I’m happy. Kevin Ahern: You’re happy? He’s happy. Alright, so we are in the process of translation. Today we’re going to look at it up close […]

Facial Selectivity and Examples of Asymmetric Synthesis

Welcome back , last time we were discussing, the stereochemistry of addition of nucleophile to a carbonyl in an acyclic system first, which is attached with an alpha stereogenic center and we have covered the crams rule, the different kinds of rules like crams rule then felkins rule the to predict the major product that […]

The Structure of Proteins, and Building Beach Necklaces

A protein is a chain of amino acids that are linked together by peptide bonds. You can picture a protein as a linear chain, sort of a necklace, made of single units, single building blocks, that are called amino acids, and that are bound together one after the other. This linear necklace will then fold […]
