Description
AHK-Cu is a synthetic copper-binding tripeptide research compound consisting of the amino acid sequence Ala-His-Lys complexed with copper(II). It is supplied as a high-purity lyophilized material for laboratory use only.
The compound is typically described as Copper Tripeptide-3 and is structurally related to GHK-Cu, differing by an alanine substitution in place of glycine at the first position. Reported specifications commonly include a molecular weight of approximately 417 g/mol and a molecular formula of C₁₅H₂₅CuN₆O₄. Identity and purity are confirmed by HPLC and mass spectrometry.
In laboratory and preclinical research, AHK-Cu has been investigated for effects on copper-peptide signaling, including studies related to dermal papilla and hair-follicle models and extracellular-matrix pathways in experimental systems. These findings are limited to research settings and do not establish approved medical use.
This material is not approved for human or veterinary use and is not intended for consumption.
