【摘要】 大豆种子的贮藏蛋白主要由2种球蛋白组成,伴大豆球蛋白(conglycinin)是其中一种,它由3个不同的亚基组成。文中对伴大豆球蛋白进行了分离纯化,并研究了其体外经过胃蛋白酶水解后的肽对双歧杆菌增殖的影响。结果表明,分离纯化的伴大豆球蛋白纯度为90.13％,可供生理功能的研究,经胃蛋白酶水解后的肽能够促进双歧杆菌的增殖,表现出一定的生物活性作用。更多还原

【Abstract】 The major soybean storage proteins are two globulin, one of these globulins is cong-lycinin, which consists of three major subunits. In this study, we separated the conglycinin from soy-bean and investigated the properties of the peptide derived from pepsin digest of conglycinin. The invitro experiments showed, their activity on the growth of Bifidobacterium longum. The purity ofconglycinin separated from soybean is 90.13%, which can also be used for the study of physiology.更多还原
