The present invention provides a process for preparingna phospholipid in an aqueous system in which hydrolysis isnextremely controlled, and the synthetic yield is improved. n A process for exchanging a base of a phospholipid asna raw material by subjecting the phospholipid to the actionnof phospholipase D in the presence of a receptor having anhydroxyl group, in which the reaction is carried out in annaqueous system, a phospholipid adsorbed on a carrier is usednas a raw material phospholipid, and the receptor and thenphospholipase D are used in free forms. |
