From Wikipedia, the free encyclopedia
Fructose, an example of a ketose. The ketone group is the double-
bonded oxygen.
A ketose is a sugar containing one ketone group per molecule.
With 3 carbon atoms, dihydroxyacetone is the simplest of all ketoses and is the only one having no optical activity. Ketoses can isomerize into an aldose when the carbonyl group is located at the end of the molecule. Such ketoses are reducing sugars.
