Description
AHK-Cu | Copper Tripeptide Complex – Research Peptide
AHK-Cu is the copper(II) complex of the tripeptide alanyl-histidyl-lysine (Ala-His-Lys). Like other copper-binding tripeptides, coordination occurs primarily through the imidazole nitrogen of the histidine residue, giving a stable peptide-metal complex.
AHK-Cu is structurally related to GHK-Cu, differing at the N-terminal residue where alanine replaces glycine. That single substitution is the basis for much of the comparative work on this compound, and laboratory research has examined the two complexes side by side in copper-delivery and gene-expression models.
Published research has characterized AHK-Cu in dermal papilla cell culture, in vascular endothelial models, and in cosmetic formulation science where copper peptide stability and delivery are the subject of study.
Common research applications: copper-peptide coordination chemistry, dermal papilla and follicle cell culture models, and comparative studies against GHK-Cu.

Frequently Asked Questions
What is AHK-Cu?
AHK-Cu is the copper(II) complex of the tripeptide alanyl-histidyl-lysine, supplied as a lyophilized powder for laboratory research.
How does AHK-Cu differ from GHK-Cu?
The two are structurally related copper tripeptides; AHK-Cu carries alanine at the N-terminal position where GHK-Cu carries glycine. They are frequently studied comparatively.
What purity is AHK-Cu supplied at?
Each vial contains 100mg of lyophilized AHK-Cu at 99%+ purity verified by HPLC/MS, third-party tested.
Is AHK-Cu available in other sizes?
Yes. Santa Cruz Peptides supplies AHK-Cu 50mg and AHK-Cu 100mg, both as lyophilized powder at 99%+ purity for laboratory research.
