Angiotensin
Definition
A peptide hormone with potent vasoconstrictive action, derived from a plasma precursor (angiotensinogen) through an enzymatic cascade involving renin and angiotensin-converting enzyme (ACE). This well-defined structural element plays a fundamental role in regulating arterial blood pressure, stimulating aldosterone secretion by the adrenal glands, and maintaining fluid and electrolyte balance in the body, while also serving as the primary target for modern antihypertensive treatments.
