A process for the selective hydrolysis of triglycerides to 2-acyl glycerides is disclosed. This process uses a primary lower alkyl alcohol selected from the group consisting of methanol, the primary butanols and the primary pentanols and 2-butanol, an aqueous buffer system and a 1,3-lipase. The 2-acyl monoglycerides can be used to make stereospecific 1,2-diacyl glycerides or 2,3-diacyl glycerides through esterification with acid anhydrides and 1,3-lipase catalysis. Stereospecific 1,2,3-triglycerides can be made from these materials by standard esterification reactions under conditions which control rearrangement.
