Three nitrogens from one short peptide converge on one metal ion. The amine and the imidazole are intrinsic donors; the amide nitrogen becomes a donor only when it loses its proton, which copper(II) binding promotes. The result is two fused chelate rings, which is a far more stable arrangement than a single point of attachment.
This is why a tripeptide can compete with much larger proteins for copper.
Copper(II) with four donors prefers a square-planar or slightly distorted arrangement. The three peptide nitrogens define three corners; the fourth is labile. That open position is where other ligands can approach and is the chemical reason the complex can interact with its surroundings rather than being inert.
It is also why pH matters: protonating the amide or the imidazole removes a corner.
A defined coordination means a defined species with a defined mass, colour and reactivity. GHK-Cu is not a peptide with copper nearby; it is this arrangement. Analysis confirms it by mass and by the copper isotope pattern.
GHK-Cu is supplied by REVIVE LAB UAE for laboratory research use only, with identity by mass spectrometry and purity by HPLC for the batch. It is not for human or veterinary use, and no dosing, administration or protocol guidance is provided.
