Reducing sugars: They are those sugars which can reduce Cu+ ions to Cu ions. This property is the basis of Benedict's and Fehling's test to detect the presence of glucose in urine. The property is found in all those saccharides which possess free aldehyde or ketone groups. All monosaccharides have this ability. Amongst disaccharides, sucrose (glucose + fructose) is non-reducing because both aldehyde group of glucose and ketone group of fructose participate in formation of glycosidic bond between the two. However, some other disaccharides like, lactose, maltose possess the reducing groups.
