DescriptionMyo-inositol 1-phosphate, also known as inositol 3-phosphoric acid, 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 an extremely weak basic (essentially neutral) compound (based on its pKa). Myo-inositol 1-phosphate exists in all living species, ranging from bacteria to humans. myo-inositol 1-phosphate can be converted into myo-inositol; which is catalyzed by the enzyme inositol monophosphatase 1. In yeast, myo-inositol 1-phosphate is involved in the metabolic pathway called the inositol phosphate metabolism pathway.
