Abstract

Amaranth is a protein-rich seed, highly consumed in Mexico and reported as a potential source of bio-peptides with physiological function. Therefore, the objective of this study was to evaluate and identify bioactive peptide sequences from amaranth protein fractions released by pepsin and pancreatin in vitro digestion. Multifunctional bioactivities of peptides were measured through antihypertensive, antithrombotic and antioxidant assays. Peptide sequences were identified by analysis with a Nano-LC-ESI-MS/MS. With these results, it was demonstrated that the in vitro enzymatic digestion mechanism allows the release of multifunctional bioactive peptide fractions from amaranth proteins.

通过体外消化分离自A菜的蛋白质释放的新型生物活性肽序列

摘要

mar菜是富含蛋白质的种子,在墨西哥大量消费,据报道是具有生理功能的生物肽的潜在来源。因此,本研究的目的是从胃蛋白酶和胰酶在体外消化释放的protein菜蛋白级分中评估和鉴定生物活性肽序列。通过抗高血压,抗血栓形成和抗氧化剂测定,可测量多肽的多功能生物活性。通过用Nano-LC-ESI-MS / MS进行分析来鉴定肽序列。利用这些结果,证明了体外酶消化机制允许从a菜蛋白质释放多功能生物活性肽级分。
