Compound notes
GHK-Cu is a copper-binding tripeptide -- glycine, histidine and lysine (Gly-His-Lys) complexed with a copper(II) ion. It has the molecular formula C14H22CuN6O4, a molecular weight of 401.9 g/mol, and CAS number 89030-95-5. The free tripeptide without copper (GHK, CAS 49557-75-7) is a distinct compound: C14H24N6O4, 340.38 g/mol. Copper is held by three nitrogen donors -- the glycine alpha-amino nitrogen, the deprotonated Gly-His amide nitrogen and the histidine imidazole -- while the lysine side chain stays free. The resulting d-d absorption near 600 nm gives the complex its characteristic colour. First identified in human plasma in 1973, GHK-Cu is classified as a metallopeptide. It is supplied as a blue to blue-purple lyophilized powder, soluble in water, and should be kept refrigerated at 2-8 C and protected from light. This product is strictly for research purposes only.
