Identifiers, parent molecule, targets and development stage, from curated data.
AHK-Cu contains Ala-His-Lys and copper(II). It differs from GHK-Cu by its first residue. The precise query finds one hair-follicle study. The PubChem name lookup returns a hydrochloride record with a specific charge and counterion. That structure does not define all AHK-Cu preparations, so chemical identifiers and masses remain unset.
No molecular target is recorded for this peptide.
Residues, differences from the parent, calculated properties and 3D structure. Source values and calculated values are shown separately.
3 amino acids · 1 modification
No formula or molecular weight is listed for AHK-Cu (Ala-His-Lys copper complex).
Some values cannot be calculated. A modification changes this value and is not modeled here (for example a lipid, metal or linker).

3 residues. Each residue counts in one class; F and W count as aromatic.
No 3D structure
No experimental structure (PDB) and no UniProt entry for an AlphaFold model are listed for this peptide. Synthetic peptides often have neither. The sequence view above is the reference.
People first in each area, then animals, then lab cells. Counts are exact and come from studies that gave the peptide.
PepBank reads each paper before it shows the results. This search looks in Europe PMC for newer papers that PepBank has not read yet.
Counts are exact and come from studies that gave the peptide.

| EU cosmetics | Note | Commercial pages use Copper Tripeptide-3. SpecialChem lists ALANINE/HISTIDINE/LYSINE POLYPEPTIDE COPPER HCL and CosIng reference 31397. Its description covers a polymer, so exact equivalence to AHK-Cu remains unconfirmed. The exact CosIng page returned an application shell without ingredient text. Do not confuse AHK-Cu with GHK-Cu / Copper Tripeptide-1. | 21 Oct 2026 | specialchem.com (opens in a new tab) |
