Identification
Name:Inositol
DescriptionInositol 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 occuring in nature, is cis-1,2,3,5-trans-4,6-cyclohexanehexol, or myo-inositol. Other naturally occurring isomers (though in minimal quantities) are scyllo-, muco-, D-chiro-, and neo-inositol. The other possible isomers are L-chiro-, allo-, epi-, and cis-inositol. (Wikipedia)
