Abstract
Glycosides with glycerol (Gl) and trimethylolpropane (TMP) moieties we re examined as substrates for the esterification by a lipase from Cand ida cylindracea. Monoglucoside (Glc-TMP) and diglucoside (Glc2-TMP) we re effectively esterified with oleic acid and middle-chain fatty acids such as lauric and capric acids, at 40-degrees-C. Stearic, palmitic, and myristic acids also gave esters, when reaction temperature was ele vated from 40-degrees-C to 60-degrees-C. Glc3-TMP was slightly esterif ied only with the middle-chain fatty acids. The reactivity of Gl-conta ining digalactosides were lower than Gl-containing monogalactosides an d TMP-containing digalactoside. Lipases from porcine pancreas and Geot richum candidum also exhibited considerable activities for the esterif ication of the glycosides.
