| titleOfInvention | Method for producing phosphatidylethanolamine and lysophosphatidylethanolamine using non-organic solvent system and a water-soluble composition comprising the lysophosphatidylethanolamine produced by the method |
| abstract | The present invention relates to a method for preparing phosphatidylethanolamine and lysophosphatidylethanolamine, and a water-soluble composition containing lysophosphatidylethanolamine prepared by the method, wherein the method for preparing phosphatidylethanolamine according to the present invention is phospholipase D In the method for producing phosphatidylethanolamine comprising the step of reacting lecithin and ethanolamine in the presence of, the lecithin comprises at least one of phosphatidylcholine, phosphatidylethanolamine, phosphatidyl acid and phosphatidylinositol, the reaction is calcium chloride and The method for preparing lysophosphatidylethanolamine according to the present invention comprises the step of reacting lecithin and ethanolamine in the presence of phospholipase D and phospholipase A. artillery In the method for preparing lysophosphatidylethanolamine, the lecithin comprises at least one of phosphatidylcholine, phosphatidylethanolamine, phosphatidyl acid and phosphatidylinositol, and the reaction is performed in a non-organic solvent system containing calcium chloride and buffer solution It features.n n n When the phosphatidylethanolamine and lysophosphatidylethanolamine according to the present invention are used, only the buffer solution is used without the use of an organic solvent, so there is no danger of using a toxic organic solvent, and no difficulty in purification. It is not severe and the reaction efficiency is high. In particular, since the organic solvent is not used during the reaction, the separation and purification process after the reaction is simplified, and the recovery of the solvent is easier even when the organic solvent is used in the separation and purification. In addition, both high and low purity lecithin (50% or less of the lecithin content) as well as high purity lecithin can be smoothly dispersed. Also, by synthesizing phosphatidylethanolamine with water, the reaction product that forms calcium salt can be washed with water to remove enzymes and ethanolamine used in the reaction and choline produced after the reaction, so that impurities such as enzymes, ethanolamine and choline are not mixed in the product. can do. |
