应用

胰酶是由猪胰腺的外分泌细胞产生的几种消化酶的混合物。它是由淀粉酶、胰蛋白酶、脂肪酶、核糖核酸酶和蛋白酶组成的广谱蛋白酶。 它被用于 体内 消化性分析。产品P7545已可用于测定纤维素分解菌抑制剂的敏感性。
该酶与淀粉糖苷酶联用,用于食品样品中淀粉的 体外 消化。Sigma的胰酶已可用于 体外 胃蛋白酶-胰酶消化试验,同时利用瘤胃饲料残渣估计较低的肠道消化率。它还与胃蛋白酶一起被用于模拟 体外 猪胃和回肠对原料的消化。

生化/生理作用

由于胰蛋白酶、淀粉酶和脂肪酶等酶的作用,胰酶可水解蛋白质、淀粉和脂肪。 胰酶能在40°C的水中在5分钟内将不少于其25倍重量的土豆淀粉转化为可溶性碳水化合物,可在40℃,pH7.5条件下,在60分钟内消化不少于自身重量25倍的酪蛋白并可在37℃,pH9.0条件下,从橄榄油中每分钟每毫克胰酶释放不少于2微当量的酸。
胰酶由猪胰腺的外分泌细胞产生,含有胰蛋白酶、淀粉酶和脂肪酶、核糖核酸酶和蛋白酶等酶组份。 这种酶的组合使其能够水解蛋白质、淀粉和脂肪。 在 40°C 水中,胰酶在 5 分钟内将不少于其重量 25 倍的马铃薯淀粉转化为可溶性碳水化合物,在 pH7.5,40℃ 下,胰酶在 60 分钟内消化不少于重量 25 倍的酪蛋白,在 pH9.0,37℃ 下,每毫克胰酶每分钟将从橄榄油中释放不低于微当量的酸。
