  Fructose, galactose, and glucose are all simple sugars, monosaccharides, with the general formula C H O. They have five hydroxyl groups (−OH) and a carbonyl group (C=O) and are cyclic when dissolved in water. They each exist as several isomers with dextro- and laevo-rotatory forms that cause polarized light to diverge to the right or the left.
