摘要: 本实验研究了花生水酶法提油中的另一产物——花生肽的抑制血管紧张素转换酶(Angiotensin converting enzyme,ACE)活性,并对其中ACE活性抑制率最高的肽进行了分离纯化和结构鉴定。该组分的氨基酸序列为Tyr-Gly-Asn-Leu-Tyr。

关键词: 花生肽, 抑制ACE活性, 分离, 氨基酸序列

Abstract: The angiotensin converting enzyme (ACE) inbibitory peptide with the highest ACE inhibitory activity was isolated and purified from peanut peptides,the byproducts in the aqueous enzymatic extraction process of oil from peanut. The amino acid sequence of this peptide is Tyr-Gly-Asn-Leu-Tyr.

Key words: peanut peptides, ACE inhibitory activity, isolation, amino acid sequence
