Kisspeptin-10
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.

Identity & structure
Primary sequence · 10 residues · C-terminal amide · Decapeptide amide (YNWNSFGLRF-NH2); the C-terminal Arg-Phe-amide is the RF-amide motif shared across the kisspeptin family. Corresponds to residues 45-54 of kisspeptin-54 (metastin)..

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.
