Introduction to Amino Acids and Polypeptides

The video discusses the structure of amino acids, their functional groups, and their importance as a major component of proteins. It explains how amide bonds are formed between carboxylic acid and amine groups, and how amino acids can react with each other to form polypeptides and proteins through a condensation reaction. The video also introduces a generic notation to represent these reactions and highlight the functional groups present in the polypeptide chains.
