In a standard chemistry experiment, many assume that only sugars with an aldehyde group can reduce Benedict's reagent. However, the ketose sugar fructose is a notable exception and will, in fact, give a positive Benedict test. This surprising result occurs due to a chemical process known as keto-enol tautomerism, which is facilitated by the alkaline conditions of the test.
