脂肪酶在有机溶剂中催化酯合成和酯交换反应

Esterification and Transesterification Catalyzed by Lipase in Organic Solvents

报道了猪胰脂肪酶在冻干时的pH值、有机溶剂的极性、反应系统的含水量、温度以及底物碳链的长度和支链对酶在有机相中催化活性的影响规律。利用该酶合成了具有玫瑰香味的月桂酸香茅酯和辛酸香茅酯。

Esterification and transesterification catalyzed by porcine pancreatic lipase in organic solvents are studied. The activity of lipase is dependent upon the pH of powdered lipase, the nature of organic solvents, temperature, water content, carbon chain length and branch of substrates. In addition, a rose-fragrant terpene alcohol ester was produced by using lipase with geraniol and carboxylic acid Clauric or octanoic acid).
