Kisspeptin-10 is a ten-residue peptide with the sequence YNWNSFGLRF and an amidated C-terminus. The full notation, YNWNSFGLRF-NH2, preserves the terminal group as well as the residue order.
Kisspeptin-10 reference identity
The supplied 10 mg report prints YNWNSFGLRF-NH2. PubChem CID 25240297 and the GSRS identity record connect this reference to the metastin 45–54 name.

How it relates to Kisspeptin-54
The Kisspeptin-54 reference ends in the same ten-residue sequence and amidated phenylalanine. Kisspeptin-10 maps to positions 45–54 of that mature 54-residue chain: 54 − 45 + 1 = 10 residues. These are mature-chain positions, not precursor numbering.IUPHAR/BPS: Kisspeptin-54 structure (opens in a new tab)PubChem: Kisspeptin-10, CID 25240297 (opens in a new tab)
Retain the length in the name. A record for the 54-residue molecule and one for the ten-residue fragment identify different chains, even though their terminal region is shared.IUPHAR/BPS: Kisspeptin-54 structure (opens in a new tab)PubChem: Kisspeptin-10, CID 25240297 (opens in a new tab)
