Residues: 10
Heavy atoms: 94
Reference slug: kisspeptin-10

These are published properties of the molecule, given for identification. Values we cannot confirm are omitted rather than estimated. What these terms mean.

What this compound is

Ten residues, the shortest fragment that retains activity at its receptor. The C-terminal amide is required; the free acid is inactive, which is why it is modelled with the amide cap.

Sequence

Kisspeptin-10 amino-acid sequence in one-letter code, numbered by residue position
1	YNWNSFGLRF

Three-letter code: Tyr-Asn-Trp-Asn-Ser-Phe-Gly-Leu-Arg-Phe

The one-letter code gives the amino-acid backbone. Terminal modifications, where a compound carries them, are accounted for in the molecular weight above but are not visible in the letters.

Residue composition

Counted directly from the sequence above. Kisspeptin-10 is built from 8 of the twenty standard amino acids across 10 positions.

Side-chain classes follow the standard grouping of the twenty proteinogenic amino acids. Composition is arithmetic over the published sequence and says nothing about how the molecule behaves.

Primary literature

5 peer-reviewed papers indexed in PubMed that name this compound in the title. Each record was checked against the database for title, journal and year rather than written from memory.

Citations are listed so the underlying research can be read directly. They describe laboratory and preclinical work on the molecule. They are not evidence of a benefit, and nothing here is an application, dose, route or outcome.
