Sorbose is a monosaccharide with six carbon atoms. This sugar is in a group of ketohexoses with the molecular formula C6H12O6.

L- Sorbose is an intermediate in the synthesis of vitamin C by Reichstein. In this process, glucose is reduced to sorbitol and subsequently oxidized with sorbose bacteria to L-sorbose. L- sorbose is further oxidized by the addition of acetone, after the subsequent splitting off of acetone and dehydration occurs vitamin C.

As with any sugar (except dihydroxyacetone), there are two enantiomeric forms, such as image and mirror image behave.

Chemical Properties

Behavior in aqueous solution

In aqueous solution it is partly to an intramolecular ring closure, resulting in a balance between the keto form and the two ring forms ( furanose form and pyranose form) adjusts the sorbose then present almost exclusively in the pyranose form.
