ACE抑制肽的制备、构效关系及活性评价研究进展

Research progress on preparation,purification and structure activity relationship of ACE inhibitory peptide

ACE抑制肽是通过食源性加工制备而成的具有降血压作用的生物活性多肽,包含抗氧化、抗炎、抗肥胖等多种潜在生理活性,将纯化后的多肽序列与ACE相互作用,研究其构效关系。ACE抑制肽具有天然可靠、无毒、安全等优点,在食品工业中受到了广泛的关注和应用。本文概述ACE抑制肽,重点对多肽的制备、分离纯化、分子模拟及原发性高血压大鼠的体内表达和体外功能活性评价等研究进展进行综述,以期为ACE抑制肽在加工和生产领域的进一步开发提供借鉴。

In this study,ACE inhibitory peptide was a biologically active peptide with blood pressure lowering effect prepared by food-based processing.It contained a variety of potential physiological activities such as anti-oxidation,anti-inflammatory,and anti-obesity.The purified peptide sequence was interacted with ACE to study its structure-activity relationship.ACE inhibitory peptide was natural and reliable,non-toxic and safe,gradually replaced artificial chemical antihypertensive inhibitors and had been widely concerned and applied in the food industry.Therefore,to summarize the knowledge of ACE inhibitory peptides,the advances in the preparation,isolation and purification,molecular simulation,in vivo expression of spontaneously hypertensive rats and in vitro functional activity evaluation of polypeptides were reviewed.It is expected to provide valuable reference for the further development of ACE inhibitory peptide in the field of processing and production.
