Abstract
The document describes a process for the preparation of N-Acyl-Phosphatidyl-Ethanolamine of formula (I) on an industrial scale, In which R, Rand Rare, independently from each other, saturated, monounsaturated or polyunsaturated acyls C-C, pure or mixed together, and X═OH or OM, where M=alkaline metal or alkaline earth, ammonium or alkylammonium. The process in question allows the conversion of lecithin of synthetic or natural origin into N-Acyl-Phosphatidyl-Ethanolamine of formula (I) of high purity, using a limited molar excess of the reagent N-acyl-ethanolamine, where the acyl is as defined above for the formula (I) through reaction of transphosphatidylation in the presence of the enzyme phospholipase D and in conditions suitable for production on an industrial scale.
