Detailed explanation-1: -Reducing Sugar (biology definition): A sugar that serves as a reducing agent due to its free aldehyde or ketone functional groups in its molecular structure. Examples are glucose, fructose, glyceraldehydes, lactose, arabinose and maltose, except for sucrose.
Detailed explanation-2: -In above options, all are monosaccharides (reducing sugars) except sucrose.
Detailed explanation-3: -Answer: Sucrose is a non-reducing sugar since it does not dissolve in water.
Detailed explanation-4: -This includes common monosaccharides like galactose, glucose, glyceraldehyde, fructose, ribose, and xylose. Many disaccharides, like cellobiose, lactose, and maltose, also have a reducing form, as one of the two units may have an open-chain form with an aldehyde group.
