Description

Angiotensin I: A decapeptide that is cleaved from precursor angiotensinogen by RENIN. Angiotensin I has limited biological activity. It is converted to angiotensin II, a potent vasoconstrictor, after the removal of two amino acids at the C-terminal by ANGIOTENSIN CONVERTING ENZYME. [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

angiotensin I : A ten amino acid peptide formed by renin cleavage of angiotensinogen. Angiotensin I has no direct biological function except that high levels can stimulate catecholamine production. It is metabolized to its biologically active byproduct angiotensin II, a potent vasoconstrictor, by angiotensin converting enzyme (ACE) through cleavage of the two terminal amino acids.

ChEBI in 2016: Improved services and an expanding collection of metabolites. Nucleic Acids Res]

angiotensin I dizwitterion : A peptide zwitterion that is the dizwitterionic form of angiotensin I having both carboxy groups deprotonated and the aspartyl amino group and arginine side-chain protonated. It is the major species at pH 7.3. [Chemical Entities of Biological Interest (ChEBI), Hastings J, Owen G, Dekker A, Ennis M, Kale N, Muthukrishnan V, Turner S, Swainston N, Mendes P, Steinbeck C. (2016). ChEBI in 2016: Improved services and an expanding collection of metabolites. Nucleic Acids Res]

angiotensin (1-9) : A nine amino acid peptide which is formed when angiotensin converting enzyme 2 (ACE2) hydrolyzes the carboxy terminal leucine from angiotensin I. It is a anti-cardiac hypertrophy agent.
