Question

Quizplus · Accepted Answer

Sucrose is not a reducing sugar because it has a glycosidic bond between its glucose and fructose molecules, which prevents it from undergoing the oxidation-reduction reactions that are characteristic of reducing sugars. Fructose, glucose, glyceraldehyde, and ribose are all reducing sugars because they have free aldehyde or ketone groups that can react with Benedict's reagent or Tollens' reagent.
