Description

myo-Inositol, also known as inosite or MI, belongs to the class of organic compounds known as cyclohexanols. Cyclohexanols are compounds containing an alcohol group attached to a cyclohexane ring. myo-Inositol is an extremely weak basic (essentially neutral) compound (based on its pKa). myo-Inositol exists in all living species, ranging from bacteria to humans.
