Abstract
The angiotensin-I converting enzyme (ACE) inhibitors from laver hydrolysate was isolated. Among the 13 kinds of proteases, Maxazyme NNP was most effective for preparing the high ACE inhibitory compound. In extraction conditions of ACE inhibitory peptide from laver hydrolysate, ACE inhibitory activity of hydrolysate treated with diethylether for decolorization and that of
본 연구는 김의 Maxazyme NNP 가수분해물로부터 여러 단계의 column chromatography 및 HPLC를 통해 ACE 저해 peptide를 분리, 정제하여 이의 분자량과 amino acid sequence를 분석하였다. ACE 저해 효과가 큰 저분자 peptide의 함량이 많은 가수분해물을 얻기 위한 최적의 단백질 가수분해 효소를 선정하기 위하여 시험한 결과, Maxazyme NNP에 의한 가수분해물의 ACE 저해효과가
