Phosphatidylserine decarboxylase proenzyme, mitochondrial
Phosphatidylethanolamine N-methyltransferase
Ethanolamine-phosphate cytidylyltransferase
Cytidine triphosphate + O-Phosphoethanolamine → CDP-ethanolamine + Pyrophosphate
Adenosine triphosphate + Ethanolamine → Adenosine diphosphate + Hydrogen Ion + O-Phosphoethanolamine
Adenosine triphosphate + Choline → Adenosine diphosphate + Phosphorylcholine
Phosphatidylcholine Biosynthesis PC(22:4(7Z,10Z,13Z,16Z)/22:2(13Z,16Z))
Cytidine triphosphate + Phosphorylcholine → CDP-Choline + Pyrophosphate
