Detailed explanation-1: -Examples. All monosaccharides are reducing sugars because they either have an aldehyde group (if they are aldoses) or can tautomerize in solution to form an aldehyde group (if they are ketoses). This includes common monosaccharides like galactose, glucose, glyceraldehyde, fructose, ribose, and xylose.
Detailed explanation-2: -Explanation : The compound having aldehyde, ketone or hemiacetal can act as reducing sugar.
Detailed explanation-3: -Maltose (glucose + glucose) and lactose (galactose + glucose) have a free aldehyde group and thus are reducing sugars.
Detailed explanation-4: -The sugars which have a free aldehyde or ketone group, in other words if the aldose C1 and ketose C2 are not involved in any bond formation, are known as reducing sugars. The free aldehyde or ketone group enables them to work as reducing agents.
