Metabolite Identification
Common Namemyo-Inositol 1-phosphate
Descriptionmyo-Inositol 1-phosphate, also known as I1P or ins(1)p, belongs to the class of organic compounds known as inositol phosphates. Inositol phosphates are compounds containing a phosphate group attached to an inositol (or cyclohexanehexol) moiety. myo-Inositol 1-phosphate is a metabolite of inositol phosphate metabolism and the phosphatidylinositol signalling system. Inositol phosphatases (EC:3.1.3.25) play a crucial role in the phosphatidylinositol signalling pathway. Expression is substantially higher in the subcortical regions of the brain, most prominently in the caudate. The phosphatidylinositol pathway is thought to be modified by lithium, a commonly prescribed medication in treating bipolar disorder (OMIM: 605922 ).
