Organic Chemistry Lecture Videos: Second Semester
In this video I'll teach you about protein chemistry. I'll begin by teaching you about amino acids and their structures, including the 20 most common amino acids found in all living things. These are separated into four different categories, according to structure, for which I've created different humorous acronyms, to help you memorize them. I'll teach you about amino acid stereochemistry (contrasting D and L amino acids), and the pKa of amino acids' various acidic groups, which explains why amino acids typically exist as zwitterions at physiological pH. I'll conclude by teaching you how to figure out an amino acid's predominant structure at any pH.
