Solution - What Are Reducing and Non-reducing Sugars? - Classification of Carbohydrates

Question

What are reducing and non-reducing sugars?

Solution

Carbohydrates are classified as

(a) Reducing sugars:- They reduce Fehling’s solution and Tollens’ reagent. All monosaccharides, whether aldoses or ketoses, are reducing sugars.
Disaccharides in which aldehydic and ketonic groups are free behave as reducing sugars.

Examples: Maltose, lactose

(b) Non-reducing sugars: They do not reduce Fehling’s solution and Tollens’ reagent. Disaccharides in which aldehydic or ketonic groups are bonded behave as nonreducing sugars.

Example: Sucrose
