Identification
Name: Glycerophosphocholine
Description:Glycerophosphorylcholine (GPC) is a choline derivative and one of the two major forms of choline storage (along with phosphocholine) in the cytosol. Glycerophosphorylcholine is also osmolyte. GPC is an intermediate of glycerophospholipid metabolism. It is converted from both 2-acyl-sn-glycero-3-phosphocholine and 1-acyl-sn-glycero-3-phosphocholine by lysophospholipase L2 (EC:3.1.1.5). It is converted to choline and sn-glycerol 3-phosphate by glycerophosphodiester phosphodiesterase (EC:3.1.4.46). (KEGG)
