Chemical Information
FooDB NameAngiotensin III
DescriptionAngiotensin III (AngIII) is one of the N-terminal angiotensin degradation products of angiotensin II. AngIII shares some of its properties with Ang II, including chemotaxis and production of growth factors and chemokines. AngIII generated within the brain acts within neural circuits of the central nervous system to regulate body fluid balance. The stimulation of vasopressin release by AngIII is thought to be one of the mechanisms by which AngIII controls volume homeostasis under conditions of hypovolemia, by reducing renal water loss and increasing blood pressure. Brain aminopeptidase A, the enzyme forming central AngIII, could constitute a putative central therapeutic target for the treatment of hypertension. (PMID: 17210474, 11751722, 11295571) [HMDB]
