槐糖内酯是一种生物表面活性剂,槐糖内酯经脂酶修饰后,并未得到断裂内酯键的槐糖脂开环衍生物,而是有选择性地水解掉糖上的一个乙酰基。

The lactonic sophoroselipid is a kind of biosurfactant. It was modified by lipases. Lactonic sophoroselipid was hydrolysized selectively by lipase to eliminate one acetate group of the sugar and the open ring derivative of sophoroselipid was not obtained in our experiment.
