De novo (Kennedy pathway) synthesis of phosphatidylcholine (PC) involves phosphorylation of choline (Cho) to phosphocholine (PCho) followed by condensing with cytidine triphosphate (CTP) to form CDP-choline (CDP-Cho). Diacylglycerol (DAG) and CDP-ETA together then form PC. Alternatively, PC is formed when phosphatidylethanolamine (PE) is methylated by phosphatidylethanolamine N-methyltransferase (PEMT) (Henneberry et al. 2002; Wright & McMaster 2002).
