Copper-dependent enzymes include cytochrome c oxidase in the respiratory chain and superoxide dismutase in oxidative defence. Without copper, neither works.
Loose copper(II) cycles between oxidation states and can drive chemistry that generates reactive species capable of damaging lipids, proteins and DNA. The same property that makes it useful in an enzyme active site makes it hazardous outside one.
By never letting much of it go free. Copper is handed from one binding protein to another along defined routes — chaperones delivering it to specific destinations rather than releasing it into the cytosol.
The estimate often quoted is that the free copper concentration inside a cell is vanishingly small. Whether or not the precise figure holds, the principle is well supported: copper travels bound.
GHK binds copper(II) with high affinity through its histidine imidazole, N-terminal amine and backbone nitrogen. That is the basis of the long-standing proposal that it functions in copper transport, which is how the compound was framed when it was first isolated from plasma.
It is also why the complex rather than the free tripeptide is treated as the species of interest, and why a certificate for GHK-Cu reports the complex.
