Copper Chelation and Delivery At the most fundamental level, GHK functions as a copper chelator and delivery system - the tripeptide binds Cu with exceptionally high affinity (binding constant approximately 10 M, among the highest known for biological copper chelators), forming a square planar coordination complex where the copper ion is coordinated by the nitrogen atoms of the terminal amino group, the two peptide bonds, and the imidazole nitrogen of histidine

Samples were run on either a SeQuant ZIC-pHILIC LC column, 5 m, 150 4.6 mm (MilliporeSigma, Burlington, MA) with a SeQuant ZIC-pHILIC guard column, 20 4.6 mm (MilliporeSigma, Burlington, MA) or an Atlantis Premier BEH Z-HILIC VanGuard FIT column, 2.5 m, 2.1 mm 150 mm (Waters, Milford, MA)
