A C-terminally amidated decapeptide, written in single-letter form as YNWNSFGLRF-NH2. It is the C-terminal ten residues of kisspeptin-54 — the full-length KISS1 gene product also called metastin — and retains the amidated Arg-Phe (RF-amide) motif shared across the kisspeptin family; the synonym "Metastin (45-54)" names exactly those ten residues. Its nine stereocentres are all L-configured (glycine at position 7 is achiral). The human decapeptide is the record used here; the rat analog is a distinct compound with a different formula.

Reference context

Kisspeptin-10 is the ten-residue C-terminal fragment of the KISS1 gene product, the C-terminally amidated decapeptide Tyr-Asn-Trp-Asn-Ser-Phe-Gly-Leu-Arg-Phe-NH2 (YNWNSFGLRF-NH2), ending in the Arg-Phe-amide motif that defines the kisspeptin family. 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 C63H83N17O14 and the values computed from it. No biological activity, mechanism, or use is described or implied.

How Kisspeptin-10 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.

What are the key chemical identifiers for Kisspeptin-10?
The CAS Registry Number for Kisspeptin-10 is 374675-21-5. Its PubChem CID is 25240297 and its InChIKey is RITKWYDZSSQNJI-INXYWQKQSA-N.
Is Kisspeptin-10 a peptide?
Yes. Kisspeptin-10 is a peptide — a chain of amino-acid residues joined by peptide bonds, 10 residues in length. Its identity is defined by that sequence and its molecular mass.
How is Kisspeptin-10 stored and reconstituted?
As a research material, Kisspeptin-10 is typically handled as a lyophilized (freeze-dried) powder. It is kept desiccated and cold — commonly 2–8 °C for short periods and −20 °C for longer storage — and reconstituted in sterile or bacteriostatic water. This is storage and handling information only, not a use protocol.
Does Lineará sell Kisspeptin-10?
No. Kisspeptin-10 is listed here only as an analytical reference entity. It is not part of the Lineará formulary, has no price or certificate of analysis, and is not offered for sale.
Is Kisspeptin-10 approved for human use?
No. Kisspeptin-10 is presented strictly as characterization reference data. It is not a drug, is not approved for any human or veterinary use, and must not be administered to humans or animals.
