AHK-cu

AHK-Cu is a synthetic tripeptide — Ala-His-Lys — bound to a copper(II) ion, produced for controlled laboratory research into follicular and dermal signaling. The histidine and lysine residues form the copper-binding site, and the complex is studied as a vehicle for delivering copper to cells in a bound rather than free ionic form. In scientific literature, AHK-Cu is studied for its effect on isolated human hair follicles in culture. The broader copper-tripeptide class, chiefly GHK-Cu, is studied for interaction with fibroblast collagen synthesis, matrix metalloproteinase expression, keratinocyte integrin signaling, and tissue remodeling gene expression in controlled in vitro and preclinical models.
