RESUMO
Hypertension is now a major problem threatening people health in the world. Angiotensin-I-converting enzyme (ACE) plays an important physiological role in regulation of blood pressure via conversion of angiotensin I to angiotensin II. Inhibition of ACE may have an antihypertensive effect as a consequence of a decrease in blood pressure. A number of terrestrial-derived peptides have been reviewed about their in vitro and in vivo ACE-inhibitory activities. Marine organisms are potentially an untapped source of drugs and value-added food production. The aim of this review is to discuss the marine-derived ACE-inhibitory peptides from sources, production, structure aspects, and their future prospects as functional food or novel therapeutic drug candidates.
