Why is sucrose a non reducing sugar if it contains Glucose?
What is notable about sucrose is that unlike most disaccharides, the glycosidic bond is formed between the reducing ends of both glucose and fructose, and not between the reducing end of one and the non reducing end of the other. This linkage inhibits further bonding to other saccharides. Since it contains no anomeric hydroxyl groups, it is classified as a non reducing sugar. Sucrose is non-reducing in Benedict’s Reagents. Therefore, no colored precipitate is formed.
