Hexose sugar is a monosaccharide with 6 carbon atoms. The chemical formula of hexose is \(\mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6}\), common examples of hexose sugars are glucose, galactose, mannose and all these are aldoses whereas fructose is ketose. Glucose, galactose and mannose are epimers i.e they differ from one another at units of symmetry.
