四种蛋白酶酶解对桦褐孔菌多糖的α-葡萄糖苷酶抑制活性影响OA北大核心CSCDCSTPCD
Effects of four kinds of proteases on α-glucosidase inhibitory activity of polysaccharide from Inonotus obliquus
为了探究桦褐孔菌高温水提粗多糖(High temperature water-extracted polysaccharides,HIOP)中结合蛋白质组成键型与其α-葡萄糖苷酶抑制活性的关系,用4种不同的蛋白酶对HIOP进行酶解,测定蛋白酶水解后对其分子量组成及α-葡萄糖苷酶抑制活性的影响.结果显示,与原HIOP在10 μg/mL时的α-葡萄糖苷酶抑制率83.72％相比,经中性蛋白酶、碱性蛋白酶、胃蛋白酶和胰蛋白酶酶解处理后的HIOP,α-葡萄…查看全部>>
The relationship between α-glucosidase inhibitory activity and the composition bond type of binding protein of high temperature water-extracted polysaccharides(HIOP) that extracted from Inonotus obliquus was studied.HIOP was enzymatically digested with four different proteases,and the effect of protease hydrolysis on its molecular weight composition and oα-glucosidase inhibitory activity was determined.The inhibitory rate of α-glucosidase by original HIOP wa…查看全部>>
