A C-terminally amidated hexapeptide carrying three D-configured residues (D-Ala, D-2-Nal and D-Phe). Its defining structural feature is the unnatural residue D-2-naphthylalanine — 3-(2-naphthyl)-D-alanine — at position 2, which replaces the histidine/D-tryptophan pair that opens GHRP-6 and accounts for the nine-nitrogen composition.
Reference context
GHRP-2 is a synthetic hexapeptide amide, D-Ala-D-2-Nal-Ala-Trp-D-Phe-Lys-NH2, distinguished by the unnatural residue 3-(2-naphthyl)-D-alanine at position 2. It is listed here strictly as an analytical reference entity — it is not sold, stocked, or certified by Lineará, and has no price or certificate of analysis. The data on this page is characterization only: molecular formula C45H55N9O6 and the values computed from it. No biological activity, mechanism, or use is described or implied.
Listed solely as a characterized analytical reference — no representation is made as to any biological effect. For Research Use Only — not for human or veterinary use.
How GHRP-2 is characterized
Identity rests on the molecular formula and mass. Electrospray mass spectrometry (ESI-MS) measures the mass-to-charge ratio of the intact molecule; the average and monoisotopic masses are computed from the verified formula and cross-check the composition. The residue sequence and the modifications noted above define the structure.
