Chapter 19: Amino Acids

Amino acids are the building blocks of proteins and play a vital role in biological systems. Each amino acid contains two functional groups: an amino group (–NH₂) and a carboxylic acid group (–COOH) , both attached to the same carbon atom known as the α-carbon . The general formula of an amino acid is NH₂–CH(R)–COOH , where R represents a side chain that varies for each amino acid.
