Analytical note — GHK-Cu. This is a metal complex, not a plain peptide, and it behaves accordingly: the copper can dissociate on-column under acidic reverse-phase conditions, so an analysis may report the free tripeptide rather than the complex. Two CAS numbers circulate because one belongs to the peptide and one to the complex; both are given above rather than merged.
Identity references The molecular formula, molecular mass and CAS registry number above are taken from the PubChem record linked in the table, not from a supplier datasheet, so every figure can be checked against an independent source in one click. Sequences are given as reported in the peptide literature, in the one-letter or three-letter convention as appropriate, with any non-standard residue named in full. Where a compound exists in more than one form — a free peptide and a metal complex, a fragment and its parent protein, a modified and an unmodified analog — the form supplied is the one identified here, and the mass on the certificate of analysis is what distinguishes it.
