Phosphorylcholine (pronounced fos-fo-ryl-ko-leen) is a molecule that plays a significant role in various biological processes. It is a component of lecithin, which is a type of phospholipid found in many organisms, including humans.
Etymology
The term "Phosphorylcholine" is derived from the words "phosphoryl," referring to the presence of a phosphate group, and "choline," a quaternary ammonium salt containing an amine group and four alkyl groups.
