Inositol or cyclohexane-1,2,3,4,5,6-hexol is a chemical compound with formula C₆H₁₂O₆ or (-CHOH-)₆, 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 (former names meso-inositol or i-inositol). Inositol is a sugar alcohol. Its taste has been assayed at half the sweetness of table sugar (sucrose).
