Application
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。
Biochem/physiol Actions
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。
脂肪酶可催化三酰甘油的水解，生成甘油和游离脂肪酸。
Analysis Note
粗制品（胰脂酶）。含淀粉酶和蛋白酶活性。
通过缩二脲法测定的蛋白质。
Other Notes
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）
