研究了有机溶剂中脂肪酶催化合成糖酯的反应。用固定化玉米淀粉酶和米氏毛霉脂肪酶催化硬脂酸果糖酯和葡萄糖酯的合成，产率为10 ~ 24%。在苯基硼酸或丁基硼酸存在下，以正己烷、正庚烷、苯和甲苯为溶剂合成了葡萄糖酯。对双糖的唯一阳性反应是帕拉金糖。
The synthesis of sugar esters catalysed by lipase in organic solvents was studied. ImmobilizedCandidaandMucor mieheilipase catalysed the synthesis of fructose and glucose esters of stearic acid in tertiary butyl alcohol with yields of 10 to 24 %. In the presence of phenyl or butyl boronic acid synthesis of glucose ester was achieved in hexane, heptane, benzene and toluene. The only positive reaction on disaccharides was found with palatinose.
