Abstract

The specific activities of the trypsins and chymotrypsins, measured with synthetic substrates, varied within one order of magnitude. 2. The trout trypsin and chymotrypsin were 5-15 times as efficient in hydrolyzing casein as the remaining animals. 3. The inhibition of total caseinolytic activity in extracts of pancreatic tissue by SBTI and inhibitors in crude extracts of raw soybeans varied ten-fold. 4. The animals may be ranked as follows according to the sensitivity of the caseinolytic activity to SBTI; trout greater than fox, chicken, greater than pig greater than rat, cow greater than mink greater than man.

摘要

用合成底物测定的胰蛋白酶和糜蛋白酶的比活性在一个数量级内变化。2. 鳟鱼的胰蛋白酶和糜蛋白酶在水解酪蛋白方面的效率是其余动物的5至15倍。3. 大豆胰蛋白酶抑制剂（SBTI）对胰腺组织提取物中总酪蛋白水解活性的抑制作用以及生大豆粗提物中的抑制剂的抑制作用变化了10倍。4. 根据酪蛋白水解活性对SBTI的敏感性，这些动物可按以下顺序排列：鳟鱼大于狐狸、鸡，大于猪大于大鼠，牛大于水貂大于人。
