Benedict’s test is conducted to confirm the presence of :
The sugars which give positive results with Benedict’s reagent and Tollen’s reagent are called reducing sugars. Most monosaccharides and some disaccharides are reducing sugars. The presence of an aldehyde group that can be oxidised to -COOH group makes them reducing sugars. Monosaccharides with aldehyde groups and keto groups that can tautomerize to an aldehyde in solution form reducing sugars. Even disaccharides that have a free aldehyde ends are also reducing sugars.
