Amino acids are the basic building blocks of proteins, consisting of a central carbon atom bonded to an amino group (-NH2), a carboxyl group (-COOH), and a unique side chain (R group) that distinguishes one amino acid from another. They play crucial roles in various biological processes, including protein synthesis, enzyme function, and as precursors to neurotransmitters and other essential molecules in the body.
