Phosphatidylcholine and the cdp-choline cycle

WebPhosphatidylcholine is a major component of very low density lipoproteins (VLDLs) secreted by the liver. Hepatic phosphatidylcholine is synthesized from choline via the CDP-choline pathway and from the phosphatidylethanolamine N-methyltransferase pathway. Elimination of the methyltransferase in male mice reduces hepatic VLDL secretion. Our objective was … WebPhosphatidylcholine is the biosynthetic precursor of sphingomyelin and as such must have some influence on the many metabolic pathways that constitute the sphingomyelin cycle. …
