โœฆ Synopsis

Stearic acid modification introduced to lipase a remarkable activation for interesterification reaction. In this study, we analyzed stearic acid-modified lipase using small angle X-ray scattering (SAXS) measurements at various temperatures. We prepared lipases modified with several fatty acids and also other proteins modified with stearic acid. SAXS analysis showed that both the lipase modified with fatty acids and other proteins modified with stearic acid consisted of a lipid lamellar structure in an aqueous buffer and in n-hexane. The long spacing of the modified lipase depended on temperature and the kind of fatty acid.

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) wer

## Interesterification and hydrolysis catalyzed by fatty acid-modified lipases Native lipases often exhibit poor interesterification activity. We previously developed a fatty acid modification method to improve the activity of lipases. In this study, we applied this fatty acid modification method
