WebProteins are made up of smaller units known as amino acids and the bond linking them is known as a peptide bond. This bond is formed when the carboxyl group (-COOH) of one amino acid bonds with the amino group (– NH 2) of another amino acid releasing a molecule of water (H2O). A peptide may be dipeptide, tripeptide, and polypeptide.
