The copper coordination chemistry of GHK-Cu enables controlled cellular copper delivery while preventing the formation of reactive oxygen species characteristic of free copper toxicity, with the peptide's binding affinity (log K = 16.1) positioning it perfectly within the physiological copper transport hierarchy to facilitate controlled metal transfer to enzymatic targets including lysyl oxidase (essential for collagen cross-linking) and superoxide dismutase (critical for antioxidant defense)
