    • The present invention provides a new enzymatic process for preparing 1,2-diacylated phospholipids comprising the use of an enzyme preparation possessing phospholipase activity towards acylation at the sn-1 and sn-2 sites in a microaqueous reaction system. More particularly, the 1,2-diacyl-phospholipids produced according to the esterification/transesterification process of the present invention are obtainable in high yield and purity and carry identical desired carboxylic acid, preferably fatty acid, acyl groups at the sn-1 and sn-2 positions. The process involves esterification/transesterification (acylation) of a glycerophospholipid, preferably glycerophosphoryl choline (GPC) with a desired carboxylic acid, preferably fatty acid, or their derivatives in the presence of the above mentioned appropriate enzyme preparation. The process of the invention further relates to a process for the production of 1-acyl-2-lyso-glycerophospholipid, preferably 2-lyso-PC by reacting glycerophospholipid, preferably glycerophosphoryl choline (GPC) with a desired carboxylic acid, preferably fatty acid, or their derivatives in the presence of a sn-1 specific phospholipase (PLA>1 1,2
    • 本发明提供了用于制备1,2-二酰化磷脂的新的酶法,其包括在微水反应体系中使用具有磷脂酶活性以在sn-1和sn-2位点进行酰化的酶制剂。 更具体地,根据本发明的酯化/酯交换方法生产的1,2-二酰基磷脂可以高产率和纯度获得,并且在sn-1和sn上具有相同的所需羧酸,优选脂肪酸酰基 -2职位。 该方法包括在上述合适的酶制剂存在下,将所需羧酸,优选脂肪酸或其衍生物的甘油磷脂,优选甘油磷酸胆碱(GPC)进行酯化/酯交换(酰化)。 本发明的方法还涉及通过使甘油磷脂,优选甘油磷酰胆碱(GPC)与所需羧酸(优选脂肪酸)反应来生产1-酰基-2-溶血甘油磷脂,优选2-溶血甘油磷酸的方法, 或其衍生物在sn-1特异性磷脂酶(PLA> 1 <或PLA> 1,2 <)和溶剂的存在下在微水介质中。
