Pal-AHK — listed in most catalogues as Palmitoyl Tripeptide-3 — is Ala-His-Lys acylated with palmitic acid at its N-terminus. The 16-carbon fatty chain turns a small, water-soluble tripeptide into an amphiphile that moves more easily into lipid phases and onto interfaces. Palmitic acid is a saturated C16 acid attached via a stable amide bond, so the lipid is an integral part of the molecule, not something that detaches.
Its AHK core is a close relative of the copper peptide AHK-Cu. In the unmodified tripeptide, copper is held by the terminal amine together with the histidine imidazole — and acylating that amine takes away one of those anchor points. Pal-AHK carries no bound copper and is investigated mainly as a lipidated signal peptide in dermal papilla, follicle and topical-delivery models. Data specific to Pal-AHK are far sparser than for AHK-Cu or GHK-Cu, so do not borrow mechanisms or results from those compounds without direct controls.
Each 200 mg vial holds lyophilised Pal-Ala-His-Lys (C31H56N6O5, 592.80 g/mol). As an amphiphile rather than a freely water-soluble peptide, how it dissolves matters as much as how much you weigh. HPLC-tested, with a certificate of analysis for each lot, and supplied purely for laboratory formulation and cell-model research — not as a cosmetic, medicine or personal-use product.

Questions about Pal-AHK (Palmitoyl Tripeptide-3)
Are Pal-AHK and AHK-Cu interchangeable?
No. Pal-AHK is Ala-His-Lys carrying an N-terminal palmitoyl chain and no copper; AHK-Cu is the copper(II) complex of the non-lipidated tripeptide. Mass, solubility, colour and coordination chemistry all differ.
Why is it listed among hair peptides?
Specialist catalogues and the sparse research discussion place it mainly next to AHK-Cu in dermal papilla and follicle-model studies. The category reflects that research setting — it is not a claim that the raw peptide affects hair.
Is there a standard CAS number for Pal-AHK?
We could not confirm a universally reliable CAS entry for this exact Pal-Ala-His-Lys-OH form, so we deliberately identify it by sequence, formula and molecular weight instead of quoting a doubtful registry number.
