| Description: The carboxyl group (COO) of one amino acid reacts with the amino group (+H3N) of the adjacent amino acid to form a covalent peptide bond that links amino acids in a polypeptide chain. Amino acids contain a central carbon (the -carbon) and an R-group, here identified as R1 and R2The carboxyl group (COO) of one amino acid reacts with the amino group (+H3N) of the adjacent amino acid to form a covalent peptide bond that links amino acids in a polypeptide chain.
