摘　　要： 生物活性肽是蛋白质中隐藏着的可在体内发挥一定生理功能的活性肽段。目前已从食物蛋白中获得了具有免疫调节、抑菌、抗病毒、抗肿瘤、抗血栓形成、抗高血压等功能的多肽,其中血管紧张素转化酶(ACE)抑制肽是研究热点之一。ACE通过产具有升压作用的血管紧张素Ⅱ和降解扩张血管的舒缓激肽在调节血压中发挥着重要作用。ACE抑制肽可通过消化道水解、发酵和熟化过程、体外酶解和遗传重组方法而获得,并可作为功能因子添加到功能食品中,相关产品已上市或研发中。本文对ACE抑制肽的生产及其构效关系研究进展等进行综述。 Bioactive peptides are peptides with physiological functions in the body,such as immunomodulatory,antimicrobial,anticancer,antivirus,antithrombotic and antihypertension functions.Currently,peptides from foods with angiotensin converting enzyme（ACE） inhibitory activity are the focus of intense study.ACE plays a vital role in the regulation of blood pressure by producing potent vasoconstrictor angiotensine II,as well as by inactivating the vasodilating bradykinin.ACE inhibitory peptides have widely been produced by gastrointestinal digestion,fermentation and maturation process,enzymatic hydrolysis and genetic recombination.These inhibitory peptides may be incorporated into functional foods and several products are currently commercially available or under development.This paper presents an overview of antihypertensive peptides derived from food protein.
