Chemical identity

• Peptide sequence (N- to C-terminus): Gly-His-Lys
  One-letter code: GHK
• Free peptide (GHK): molecular formula C₁₄H₂₄N₆O₄; molecular weight ≈ 340.38 g/mol; CAS 49557-75-7; PubChem CID 73587.
• 1:1 GHK-Cu(II) complex: commonly represented as C₁₄H₂₂CuN₆O₄ or the cation C₁₄H₂₃CuN₆O₄⁺; molecular weight ≈ 401.9–403 g/mol (depending on exact protonation state); CAS 89030-95-5 (prezatide copper); also listed under related CAS numbers for specific salts (e.g., acetate forms).
• The complex is formed by high-affinity binding of Cu²⁺. At physiological pH, copper is coordinated primarily by the N-terminal amino group of glycine, the deprotonated amide nitrogen of the Gly–His peptide bond, and the imidazole nitrogen of histidine, producing a square-planar (or related) geometry with a labile fourth coordination site. A 2:1 peptide:copper species can also form under certain conditions.
