Abstract
A process for producing phosphatidylserine having a long chain unsaturated fatty acid in its side chain. In this process, a natural lecithin containing long chain unsaturated fatty acid side chain is used as the starting material. Using the natural lecithin as a substrate for reaction, phospholipase-D is caused to act on the substrate under the presence of serine, whereby phosphatidylserine having a side chain derived from the long chain unsaturated fatty acid can be easily obtained through a single step reaction.
Claims15
A process for producing phosphatidylserine having a long chain unsaturated fatty acid side chain, comprising preparing a substrate comprising natural lecithin containing a long chain unsaturated fatty acid as a tatty acid side chain, and applying phospholipase-D to said natural lecithin of said substrate in the presence of serine, said natural lecithin containing at least one long chain unsaturated fatty acid selected from the group consisting of n-3 eicosapentaenoic acid, n-3 docosahexaenoic acid and n-6 arachidonic acid.
