| 摘要: |
Both n-3 polyunsaturated fatty acids (n-3 PUFA) and phospholipids have a lot of special functions onhuman body. n-3 PUFA includes -linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Among them, ALA is the precursor of EPA and DHA. The synthesis of ALA-containing phospholipids can solve the problems of low content of EPA and DHA in phospholipids and show an increased double effect on human body. At a water activity of 0.33, a rapid and efficient method was used for kinetics of the transesterification of phosphatidylcholine (PC) with -linolenic acid ethyl ester (ALAEE). The rate equation was obtained using palmitic acid ethyl ester (PAEE) as index for reaction rate and the reaction proved to proceed via a Ping-Pong mechanism without inhibition by both the substrates. |
