Definition

organic molecular entity consisting of two or more amino acid residues linked by peptide bonds

Explanatory Notes

A peptide is formed through condensation reactions between amino acids, producing amide linkages known as peptide bonds. After peptide-bond formation, the peptide contains amino acid residues rather than free amino acid molecules as parts. The term generally refers to molecules composed of α-amino acid residues, but may also include peptides containing residues derived from other amino acid types.

Examples

Glutathione; Oxytocin; Bradykinin; Angiotensin II
