Chemical Behavior as a Copper Chaperone From a biochemical standpoint, GHK-Cus structure is of interest: the glycine and histidine residues coordinate copper(II) in a square-planar pyramid, with additional interactions involving lysine residues in adjacent complexes

and (4) the 2-oxoadipate dehydrogenase complex, all of which share the same architecture

AHK-Cu works through similar copper-binding mechanisms with a focus on scalp and hair follicle health
