Angiotensin II human is a peptide hormone that causes vasoconstriction and a subsequent increase in blood pressure. IC50 value: Target: Angiotensin receptor In nature, angiotensin II (Ang II) is formed by the action of angiotensin converting enzyme (ACE), which cleaves the C-terminal -His-Leu from the decapeptide, angiotensin I.

Background Information

Angiotensin II (Ang II) is an octapeptide hormone that plays a central role in cardiovascular homeostasis. ......by AdooQ BioScience, LLC
Angiotensin II is an endogenous potent vasoconstrictor peptide typically generated by the removal of two residues from angiotensin I by angiotensin-converting enzyme (ACE) by binding to both the AT1 and the AT2 receptors. ......by BOC Sciences
Angiotensin II human is converted by Angiotensin I through removal of two C-terminal residues by the enzyme angiotensin-converting enzyme (ACE). Angiotensin II is mediated by AT1 and AT2 receptors, which are seven transmembrane glycoproteins with 30% sequence similarity. ......by MedChemexpress Co., Ltd.
Angiotensin II is an endogenous potent vasoconstrictor peptide. The amino acid sequence of angiotensin II is Asp-Arg-Val-Tyr-Ile-His-Pro-Phe | His-Leu. Angiotensin II increases blood pressure by stimulating the Gq protein in vascular smooth muscle cells (which in turn activates an IP3-dependent mechanism leading to a rise in intracellular calcium levels and ultimately causing contraction). In addition, angiotensin II acts at the Na/H exchanger in the proximal tubules of the kidney to stimulate Na reabsorption and H excretion which is coupled to bicarbonate reabsorption. This ultimately results in an increase in blood volume, pressure, and pH. Angiotensin II is degraded to angiotensin III by angiotensinases located in red blood cells and the vascular beds of most tissues. It has a half-life in circulation of around 30 seconds, whereas, in tissue, it may be as long as 15–30 minutes. ......by MedKoo Biosciences, Inc.
