Origin of reninfrom Classical Latin renes, kidneys + -in
An enzyme released by the kidneys that cleaves a plasma protein to produce an inactive form of angiotensin which is then converted to an active form that raises blood pressure.
Origin of reninLatin rēnēs kidneys -in
- (biochemistry) An circulating enzyme released by mammalian kidneys that converts angiotensinogen to angiotensin-I. Because its activity ultimately leads to formation of angiotensin-II and aldosterone, this hormone plays a role in maintaining blood pressure.
