A series of 1, 3-diacylglycero-2-phosphocholines (1, 3-PCs) with acyl chain lengths of C8– C18 were synthesised by chemical introduction of the phosphocholine moiety into the regioisomerically pure 1, 3-diacylglycerols, which were obtained from glycerol and the vinyl esters of fatty acid by means of lipase from Rhizomucor mihei. The 1, 3-PCs being regioisomers of the natural glycerophospholipids were studied with respect to their ...
