key term - Angiotensin-converting enzyme (ACE)

Definition

Angiotensin-converting enzyme (ACE) is an enzyme that plays a crucial role in regulating blood pressure by converting angiotensin I, an inactive hormone, into angiotensin II, a potent vasoconstrictor. This process is part of the renin-angiotensin system which helps control blood pressure and fluid balance in the body.
