Question
Explain the difference between reucing and non-reducing sugars with examples.

Answer

Reducing sugars have reducing properties, hence they reduce Fehling's solution and Tollens' reagent, like- all monosaccharides, maltose and lactose. Non-reducing sugars do not have reducing properties, hence they do not reduce Fehling's solution and Tollens' reagent. Example : Sucrose.
