✦ Synopsis


A simple synthesis of sugar fatty acid esters was developed in a nonaqueous solution using lipase modified by synthetic detergent. Esterification of sugar was accelerated by continuous removal of water from the reaction mixture with a molecular sieve. When glucose and palmitic acid (1:1 by mole) were used as the starting substrates, more than 90% of glucose was converted to its ester in this system. The resultant product was 6-O-palmitoylglucose. Other mono-or disaccharides were also esterified by the modified lipase with high yield. It was shown that the modified lipase might act as a catalyst for the synthesis of sugar fatty acid esters.
