Tripeptide

A tripeptide (example Val-Gly-Ala) with
green marked amino end (L-Valine) and
blue marked carboxyl end (L-Alanine)

A tripeptide is a peptide derived from three amino acids joined by two or sometimes three peptide bonds.[1] As for proteins, the function of peptides is determined by the constituent amino acids and their sequence. In terms of scientific investigations, the dominant tripeptide is glutathione (γ-L-Glutamyl-L-cysteinylglycine), which serves many roles in many forms of life.[2]
