應用

猪胰腺脂肪酶已被用于:
  • 分析甘油三酯的2-位脂肪酸。
  • 确定耐受消化酶作用的植物来源的难消化部分。
  • 作为研究茶碱溶出曲线的溶出介质组分。
脂肪酶在工业上用于拆分手性化合物和生物柴油的酯交换生产。

生化/生理作用

脂肪酶可催化水溶液中酯的水解和非水溶液中酯的合成。它们通过水解聚对苯二甲酸乙二酯中的酯键,产生羟基和羧基。

脂肪酶可催化三酰甘油的水解,生成甘油和游离脂肪酸。

品質

粗制品(胰脂酶)。含淀粉酶和蛋白酶活性。

單位定義

一个酶活性单位是指在pH 7.4、温度37℃条件下,在1小时内水解三醋酸甘油酯而释放1.0微当量的脂肪酸所需的酶量。(以橄榄油为底物时,所用pH值为7.7)

分析報告

通过缩二脲法测定的蛋白质。
