| Abstract: |
| Phosphatidyl-glycosides （PtdGlc） is composed of saturated fatty acyl chains（C18∶?0 and C20∶?0） and the polar head of the glycosides. Phosphatidyl-fructose belongs to one of the phosphatidyl-glycosides. With soybean lecithin and fructose as raw materials, phospholipase D as catalyst, an enzymatic method for synthesizing phosphatidyl-fructose in aqueous system was developed. Through the regulation of substrate ratio, pH, reaction temperature and reaction time, the optimal reaction conditions of phosphatidyl-fructose were established as follows: reaction temperature 40?℃, pH 6, reaction time 12 h, molar ratio of fructose to soybean lecithin 1∶?45, enzyme dosage 90 U/mL. Under the optimal reaction conditions, the synthesis rate of phosphatidyl-fructose in aqueous system was 90% or so. |
