About

Inositol or cyclohexane-1,2,3,4,5,6-hexol is a chemical compound, a six-fold alcohol (polyol) of cyclohexane. It exists in nine possible stereoisomers, of which the most prominent form, widely occurring in nature, is cis-1,2,3,5-trans-4,6-cyclohexanehexol, or myo-inositol. Inositol is a carbohydrate, though not a classical sugar. Its taste has been assayed at half the sweetness of table sugar (sucrose). Myo-Inositol plays an important role as the structural basis for a number of secondary messengers in eukaryotic cells, the various inositol phosphates. In addition, inositol serves as an important component of the structural lipids phosphatidylinositol (PI) and its various phosphates, the phosphatidylinositol phosphate (PIP) lipids.
