Choline biosynthesis

Choline can also be produced by the CDP-choline route, cytosolic choline kinases (CK) phosphorylate choline with ATP to phosphocholine (PChol). This happens in some cell types like liver and kidney. Choline-phosphate cytidylyltransferases (CPCT) transform PChol to CDP-choline (CDP-Chol) with cytidine … See more Choline /ˈkoʊliːn/ is a cation with the chemical formula [(CH3)3NCH2CH2OH] . Choline forms various salts, for example choline chloride and choline bitartrate. See more Choline is widespread in nature in living beings. In most animals, choline phospholipids are necessary components in cell membranes, in the membranes of cell organelles, and in very low-density lipoproteins. See more Biosynthesis In plants, the first step in de novo biosynthesis of choline is the decarboxylation See more Choline and its derivatives have many functions in humans and in other organisms.

Although multiple pathways exist for the biosynthesis of phosphatidylcholine, the predominant route in eukaryotes involves condensation between diacylglycerol (DAG) and cytidine 5'-diphosphocholine (CDP-choline or citicoline). The conversion is mediated by the enzyme diacylglycerol cholinephosphotransferase. Another pathway, mainly operative in the liver involves methylation of phosphatidylethanolamine with S-adenosyl methionine (SAM) being the methyl grou… texas master social worker verification https://annuitech.com
