Angiotensin is a peptide hormone that causes vasoconstriction and a subsequent increase in blood pressure. It is part of the renin-angiotensin system, which is a major target for drugs that lower blood pressure. Angiotensin also stimulates the release of aldosterone, another hormone, from the adrenal cortex.
This is a carboxypeptidase enzyme located primarily in the lungs which splits off the His-Leu of Angiotensin I to form Angiotensin II. Angiotensin II This has a half life of 1 to 2 minutes and is produced from Angiotensin I by ACE. It is a potent vasocronstrictor in the arterioles and increases BP. It acts o the brain to stimulate thirst and increase secretion of ADH. It increases secretion of Aldosterone from the zona glomerulosa of Adrenal Cortex.
