WebBenedict’s test was performed on three carbohydrates, depicted from left to right: fructose, glucose, and sucrose. The solution containing sucrose remains blue because sucrose is a nonreducing sugar. These reactions have been used as simple and rapid diagnostic tests for the presence of glucose in blood or urine. For example, Clinitest ... WebFructose is a ketose. ketones usually do not give a positive reaction with Benedict reagent. why is fructose oxidized by Benedicts reagent fructose will have RED ppt because it is a reducing sugar. reducing sugar will always give positive.
