PROCESS FOR PREPARING 2-ACYLGLYCERIDES OR 1,2-DIACYL DIGLYCERIDES OR 2,3DIACYL DIGLYCERIDES

摘要

A process for the selective hydrolysis oftriglycerides to 2-acyl glycerides is disclosed. Thisprocess uses a primary lower alkyl alcohol selected fromthe group consisting of methanol, the primary butanolsand the primary pentanols and 2-butanol, an aqueousbuffer system and a 1,3-lipase. The 2-acylmonoglycerides can be used to make stereospecific1,2-diacyl glycerides or 2,3-diacyl glycerides throughesterification with acid anhydrides and 1,3-lipasecatalysis. Stereospecific 1,2,3-triglycerides can bemade from these materials by standard esterificationreactions under conditions which control rearrangement.
