【摘要】 本文分析了中华鳖幼鳖胃肠胰组织中淀粉酶、蛋白酶、脂肪酶的最适ｐＨ、最适底物浓度及Ｎａｃｌ对淀粉酶的激活效应，在测定的最适条件下比较了三种酶在胃肠胰不同部位组织中酶活性的分布。结果表明：淀粉酶活性，胰＞十二指肠＞胃＞回肠及结肠＞直肠；蛋白酶活性，胃＞胰＞十二指肠＞回肠及结肠＞直肠；脂肪酶活性，胰＞十二指肠＞回肠及结肠＞直肠＞胃。幼鳖主要消化酶的分布兼有单胃哺乳动物与有胃鱼类的特点，并可为日粮配合提供依据。更多还原

【Abstract】 In this paper, the optimum pH, optimum substrates concentration of amylase, protease, lipase of the stomaches, pancreas and intestines of Trionyx sinensis and active effect of Nacl on the amylase were assayed, and distributions of three enzymes in the digestive tissue were determined in the optimm condition. The results showed that:activity intensity of amylase was arranged in following sequence the pancreas>duodenum>stomach>ileum and colon>rectum; activities of protease was the stomach>pancreas>duodenum>ileum and colon>rectum; activities of lipase was the pancreas>duodenum>ileum and colon>rectum>stomach.更多还原
