What Is a Tripeptide?

A tripeptide consists of three amino acid residues joined by two peptide bonds. Several of the most important bioactive peptides in research are tripeptides, demonstrating that even three residues can encode potent biological activity when the sequence is optimized.

Notable Tripeptides

  • Glutathione (gamma-Glu-Cys-Gly): The most abundant intracellular antioxidant, present at millimolar concentrations
  • GHK (Gly-His-Lys): Copper-binding tripeptide that stimulates collagen synthesis and wound healing
  • KPV (Lys-Pro-Val): Anti-inflammatory C-terminal fragment of alpha-MSH
  • RGD (Arg-Gly-Asp): Universal integrin recognition motif for cell adhesion
