[Val5] Angiotensin II, human

The octapeptide angiotensin II (Ang II) exerts a wide range of effects on the cardiovascular system. It is also implicated in the regulation of cell proliferation, fibrosis and apoptosis. Ang II is formed by cleavage of Ang I by the angiotensin-converting enzyme (ACE) or chymases. The biological activities of angiotensin II include the regulation of blood pressure, salt and water balance, and vascular tonus.
