Phosphatidylethanolamine Biosynthesis PE(20:3(8Z,11Z,14Z)/22:0)
Choline/ethanolaminephosphotransferase 1
Cytidine triphosphate + O-Phosphoethanolamine → CDP-ethanolamine + Pyrophosphate
Phosphatidylserine decarboxylase proenzyme
Ethanolamine-phosphate cytidylyltransferase
CDP-ethanolamine + DG(20:3(8Z,11Z,14Z)/22:0/0:0) → Cytidine monophosphate + PE(20:3(8Z,11Z,14Z)/22:0)
Adenosine triphosphate + Ethanolamine → Adenosine diphosphate + Hydrogen Ion + O-Phosphoethanolamine
