any of three oligopeptides occurring in plasma, an inactive form (angiotensin I) and two varieties (angiotensin II and angiotensin III) that elevate blood pressure and stimulate the adrenal cortex to secrete aldosterone.
a peptide of physiological importance that is capable of causing constriction of blood vessels, which raises blood pressure
angiotensin III n.
A heptapeptide derivative of angiotensin II that exhibits some of the vasopressor and aldosterone stimulation effects of its precursor.
angiotensin an·gi·o·ten·sin (ān’jē-ō-těn’sĭn)
Any of a group of peptides with vasoconstrictive activity that function physiologically in controlling arterial pressure.
Any of three polypeptide hormones that function in the body in controlling arterial pressure. The most important is known as angiotensin II, a powerful vasoconstrictor that stimulates steroid production by the adrenal glands, reduces fluid loss from the kidneys, and also functions as a neurotransmitter. Angiotensin II is formed from inactive angiotensin I by the action of angiotensin-converting enzyme (or ACE). See also ACE inhibitor, renin.
- Angiotensin receptor blocker
noun any of a class of drugs that block the uptake of angiotensin: used in the treatment of high blood pressure
- Angiotensin precursor
angiotensin precursor angiotensin precursor n. See angiotensinogen.
- Angiotensin-converting enzyme
angiotensin-converting enzyme angiotensin-converting enzyme n. See dipeptidyl carboxypeptidase.
angiotensinase angiotensinase an·gi·o·ten·si·nase (ān’jē-ō-těn’sə-nās’, -nāz’) n. A peptidase in tissues and plasma that degrades angiotensin II. Any of several enzymes in the blood that hydrolyze angiotensin.
