Tripeptide
A peptide of three amino-acid residues — for example GHK (in GHK-Cu) or KPV.
A tripeptide is a peptide made of three amino-acid residues. Small tripeptides can be transporter-accessible and are studied as research tools in their own right — for example KPV (Lys-Pro-Val), the C-terminal fragment of α-MSH, and GHK (glycyl-L-histidyl-L-lysine), the peptide in the copper complex GHK-Cu.
Their small, well-defined size makes tripeptides convenient, stable reference compounds in the research literature.
