प्रश्न
What are reducing and non-reducing sugars?
Advertisements
उत्तर
1. Reducing sugars: Those carbohydrates which contain free aldehyde or ketonic group and reduces Fehling’s solution and Tollen’s reagent are called reducing sugars. All monosaccharides whether aldose or ketone are reducing sugars.
2. Non-reducing sugars: Carbohydrates that do not reduce Tollen’s reagent and Fehling’s solution are called non – reducing sugars. Example Sucrose. They do not have a free aldehyde group.
