Merck, A9650-1MG, Angiotensin I human acetate salt hydrate

General description
Asp-Arg-Val-Tyr-Ile-His-Pro-Phe-His-Leu-OH.2CH3COOH.6H2O
Angiotensinogen (Angiotensin I) is a renin substrate, which is produced by the liver.

Research area: Cell Signaling
Application
Angiotensin I human acetate salt hydrate has been used:
as an external calibration standard, it was applied to α-cyano-4-hydroxycinnamic acid (CHCA) and 2,5-dihydroxybenzoic acid (DHB) matrix,
to prepare angiotensin I solution gravimetrically for hydrolysis and also used as a model peptide to demonstrate SI (système international) -traceable amino acid analysis
as an analyte to deposit on the target in the study of on-line single droplet deposition for matrix-assisted laser desorption/ionization (MALDI) mass spectrometry

Biochem/physiol Actions
Angiotensin I is a putative neurotransmitter. It is the precursor of angiotensin II and of angiotensin fragment 1-7, which are the hormones involved in regulation of fluid volume and the release of aldosterone.
Putative neurotransmitter; precursor of angiotensin II and of angiotensin fragment 1-7.
Angiotensin is a component of the renin-angiotensin aldosterone system (RAAS). This hormonal circulating system aids in regulating blood pressure by modulating potassium secretion, vascular tone, and sodium and water reabsorption. RAAS also participates in fibrosis, apoptosis, and inflammation.
