A tripeptide is a peptide composed of three amino acid By joining Peptide bond Connected. Its exact nature and function protein It is determined by the presence of amino acids and the order in which they appear. A simple example is a tripeptide made of either 3 glycine Molecule or two glycines and one alanine 。 Triglycine tripeptide can only have one structure: glycine glycine glycine. Other tripeptides may have different sequences: glycine alanine glycine, glycine glycine alanine, alanine glycine glycine. Each is a different molecule.
