Tripeptide
Peptide consisting of three amino acids joined by peptide bonds / From Wikipedia, the free encyclopedia
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]
