Phosphocholine is the phosphate of choline and the parent compound of the phosphocholine family. It has a role as an epitope, a hapten, a human metabolite, a mouse metabolite, and an allergen. It is a conjugate acid of a choline phosphate(1-). It is a natural product found in Drosophila melanogaster, Capsicum annuum, and other organisms with data available.
Phosphocholine is an intermediate in synthesizing Uridine Diphosphate Choline Ammonium Salt (U829930), a CDPcholine cholinephosphotransferase analog. Pipeline devices with Phosphorylcholine surface treatment (Pipeline Shield) could mitigate device material-related thromboembolic complications.
