Free Cu2+ is toxic (Fenton reactions, hydroxyl radicals), but the GHK-Cu complex is stable, diffusible and delivers copper in a targeted manner to copper-dependent metalloenzymes: lysyl oxidase (collagen/elastin crosslinking), Cu/Zn superoxide dismutase (SOD1, antioxidant defence), tyrosinase (controlled melanogenesis), dopamine-beta-hydroxylase
