Phosphocholine is an intermediate in the synthesis of phosphatidylcholine in tissues. Phosphocholine is made in a reaction, catalyzed by choline kinase, that converts ATP and choline into phosphocholine and ADP. Phosphocholine is a molecule found, for example, in lecithin.
It is also used by nematodes and human placentas as a posttranslational modification to suppress an immune response by their hosts.[1][2]
It is also one of the binding targets of C-reactive protein (CRP).[3] Thus, when a cell is damaged, CRP binds to phosphocholine, beginning the recognition and phagocytotic immunologic response.
Phosphocholine is a natural constituent of hens' eggs (and many other eggs) often used in biomimetic membrane studies.[4][5]
