Phosphatidylcholine Biosynthesis From Phosphoryl-Ethanolamine via CDP-N-Methylethanolamine

The phosphatidylcholine biosynthetic process that begins with an initial N-methylation with phospho-base phosphoethanolamine, followed by two downstream N-methylations on phosphatidyl-bases, phosphatidyl-N-methylethanolamine and phosphatidyl-N-dimeth.
