Thesalvagepathwayfromserinetophosphatidylcholine
The biosynthesis of membrane phospholipids occurs through distinct pathways in mammals and bacteria. In the mammalian pathway for the synthesis of phosphatidylethanolamine, ethanolamine is first phosphorylated, activated to form CDP-ethanolamine and then reacted with diacylglycerol to form phosphatidylethanolamine. Phosphatidylcholine is synthesized in mammals by a similar route. Phosphatidylserine is synthesized thr......阅读全文
