BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Sucrose is a non-reducing sugar.

Detailed explanation-2: -Since the reducing groups of glucose and fructose are involved in glycosidic bond formation, sucrose is a non-reducing sugar.

Detailed explanation-3: -Reducing sugars include glucose, fructose, glyceraldehyde, lactose, arabinose and maltose. All monosaccharides which contain ketone groups are known as ketoses, and those which contain aldehyde groups are known as aldoses. Significantly, sucrose is not a reducing sugar. It is in fact known as a non-reducing sugar.
