Angiotensin-Converting Enzyme (ACE)

Angiotensin-Converting Enzyme (ACE) is an enzyme in the body that plays a key role in controlling blood pressure. It helps convert a molecule called angiotensin I into angiotensin II, a powerful substance that narrows blood vessels and raises blood pressure. By influencing these processes, ACE helps regulate blood flow and pressure. Medications called ACE inhibitors can block this enzyme, helping to lower high blood pressure and reduce the workload on the heart, which is important in managing conditions like hypertension and heart failure.
