Vedclass · Answer

(A) reducing sugar is a carbohydrate that possesses a free aldehyde or ketone group,which allows it to act as a reducing agent. In the given options,the structure in image $821-a493$ represents a monosaccharide (glucose) in its cyclic hemiacetal form. This hemiacetal carbon (anomeric carbon) is in equilibrium with the open-chain aldehyde form in aqueous solution,making it a reducing sugar. Options $B$,$C$,and $D$ represent glycosides or derivatives where the anomeric hydroxyl group is involved in a bond (acetal formation),thus preventing the formation of a free aldehyde group and rendering them non-reducing.
