Overview

History

Copper-binding tripeptides were identified as plasma-derived activity fractions in the 1970s, with GHK-Cu characterized first. AHK-Cu was subsequently synthesized as a related copper-carrier tripeptide and has been studied largely in dermal and follicular research models.

AHK-Cu and GHK-Cu differ by one residue

These two copper tripeptides are stocked side by side and are frequently ordered in error for one another. The difference is a single amino acid at the first position.

GHK-Cu is Gly-His-Lys complexed with copper(II). AHK-Cu is Ala-His-Lys with the same copper coordination — alanine in place of glycine. Everything else about the two is shared, including the copper(II) ion that gives both their colour and much of their behaviour.

That one substitution is why they are studied together rather than interchangeably. Comparative work across the two is a standard way of probing how much of the observed matrix and follicular signalling depends on the N-terminal residue specifically, rather than on the histidine-lysine-copper arrangement the two share.

If a protocol names one, the other is not a substitute — it is the control.

Copper coordination and why assay matters

The copper(II) ion is not an impurity or an additive; it is part of the molecule, and its coordination state is what most affects whether a lot behaves as expected. A lot can assay correctly for peptide identity while carrying incomplete copper coordination, which is exactly the failure mode worth checking on the Certificate of Analysis rather than assuming.

The compound is supplied lyophilised. Reconstitution with bacteriostatic or sterile water is straightforward at tripeptide scale. Buffers containing strong chelators are generally avoided, since competing for the copper defeats the point of the complex.

Lyophilised material is stored at -20°C protected from light; reconstituted solution is refrigerated at 2-8°C. General reagent handling only.
