angiotensin I

an·gi·o·ten·sin I

(an'jē-ō-ten'sin), A decapeptide of slightly variable sequence, depending on the animal source, formed from the tetradecapeptide angiotensinogen by the removal of four amino acid residues, a reaction catalyzed by renin; a peptidase cleaves off a dipeptide (histidylleucine) to yield angiotensin II, the physiologically active form.

angiotensin I

An N-terminal decapeptide produced when renin acts on angiotensinogen. Angiotensin I is the precursor of angiotensin II but itself has no known physiologic role.
