Angiotensin I, also known as proangiotensin is formed from angiotensinogen by the action of renin. Angiotensin I has no direct biological function but is a precursor to angiotensin II through cleavage of the two terminal amino acids by angiotensin converting enzyme (ACE). Angiotensin I [Asn1,Val5,Asn9], salmon and other peptides derived from aquatic animals may inhibit ACE making them attractive targets for development of blood pressure medications.
