Enzymatic synthesis of structured 1,2-diacyl-sn-glycero-3-phosphocholines from glycerol-sn-3-phosphocholine
The synthesis of structured 1,2-diacyl-sn-glycero-3-phosphocholines (sn-1,2-PC) from glycerol-sn-3-phosphocholine (GPC) was studied by means of enzymatic acylation reactions of the two free sn- positions of the glycerol backbone. Already after 22 h high conversions (absolute yields = 100%) of GPC to...
