AHK-Cu

Description

CAS Registry Number: 682809-81-0

Molecular Formula: C₁₄H₂₄N₆O₃Cu

Molecular Weight: 416.9 g/mol

AHK-Cu is a copper-chelated tripeptide composed of alanine, histidine, and lysine. The peptide forms a stable coordination complex with copper ions, creating a well-defined structure often used in research examining metallopeptide interactions, binding behavior, and conformational stability. Its compact sequence and metal-associated configuration make it useful for analytical studies involving peptide–metal affinity, purity assessment, and chromatographic characterization.

AHK-Cu (also known as Copper Tripeptide-3, Alanine-Histidine-Lysine-Copper, or AHK copper peptide) is a synthetic tripeptide complexed with copper(II) ion. It consists of the amino acids L-alanine (Ala), L-histidine (His), and L-lysine (Lys) bound to copper, often used in cosmetic and research contexts for potential benefits like promoting hair growth, anti-aging effects on skin, and angiogenic (blood vessel formation) properties. It is structurally similar to but distinct from the more common GHK-Cu (glycyl-histidyl-lysine-copper).

Additional Info:

• Appearance: Typically a blue powder (characteristic of copper(II) complexes).
• It is researched primarily for topical applications in hair care (e.g., stimulating follicle growth, potentially more targeted for hair than GHK-Cu) and skincare (e.g., wound healing, collagen support).
• Note: Some sources confuse it with GHK-Cu (CAS 49557-75-7 for the peptide alone, 89030-95-5 for Cu complex), which has a different sequence (Gly-His-Lys) and weight (~340 for peptide, ~403–405 for Cu complex).
