About this product
KPV — Peptide Overview
KPV is a tripeptide composed of three amino acid residues: lysine, proline and valine. Its name comes from their single-letter codes—K for lysine, P for proline and V for valine.
Also described as Lys-Pro-Val or L-lysyl-L-prolyl-L-valine, the compound has a defined sequence and chemical structure. The specifications below identify KPV in its free-acid form.
Structure and Composition
KPV contains three amino acid residues joined in the order lysine–proline–valine. This order defines its primary structure and distinguishes it from other tripeptides made from the same amino acids in a different arrangement.
The sequence can be written as H-Lys-Pro-Val-OH. In this notation, H indicates the unmodified amino terminus, while OH identifies the free carboxylic acid at the opposite end of the peptide.
Terminal chemistry is part of the compound’s identity. KPV with a free-acid terminus and KPV with an amidated terminus have different chemical compositions and should be described using their respective specifications.

Understanding Compound Specifications
The abbreviation KPV identifies the amino acid sequence, but a complete specification also describes the terminal groups and any salt form. These details help distinguish the parent peptide from modified versions.
The formula and molecular weight above apply to the free-acid form. An amidated derivative or a preparation containing an additional counterion requires separate chemical information.
The 10 mg designation describes the listed compound quantity per vial. It is separate from molecular weight, which is expressed in grams per mole, and does not specify a dose or administration schedule.
