Question

Which one of the following is enriched with a non-reducing sugar?

• A. Grapes
• B. Germinating barley grains
• C. Table sugar
• D. Mother's milk

Answer 1

The correct option is C Table sugar

A reducing sugar is any sugar that is capable of acting as a reducing agent because it has a free aldehyde group or a free ketone group.

All monosaccharides are reducing sugars, along with some disaccharides, oligosaccharides, and polysaccharides.

Sucrose (a disaccharide) is also known as table sugar, sugar cane, sugar beet or usually sugar, is the non-reducing sugar among all.

The rest of the options contain reducing sugar such as grapes (glucose + fructose), germinating barley grains (maltose) and mother's milk (lactose).
