Angiotensin Converting Enzyme (ACE) Level TEST

The angiotensin converting enzyme (ACE) is an enzyme that converts angiotensin I to angiotensin II. Angiotensin II helps increase blood pressure by causing small blood vessels in the body to tighten or narrow. It is integral to the renin angiotesin which maintains blood pressure by regulation of fluid volume and vascular tension. Its peptidase action on the decapeptide angiotensinogen I result in the hydrolysis of a terminal histidyl leucine dipeptide and formation of the octapeptide angiotensin I, a potent vasoconstrictor that increase blood pressure.
