Which one of the following is a non reducing carbohydrate?
- A Maltose
- B Sucrose
- C Lactose
- D Ribose \(5\)-phosphate
Answer & Solution
Correct Answer
(B) Sucrose
Step-by-step Solution
Detailed explanation
(b) : In non-reducing sugars, a free aldehyde or ketonic group is absent. Sucrose is a non-reducing sugar formed by condensation of one molecule each of glucose and fructose with release of a water molecule. A glycosidic bond is established between carbon atom \(1\) of glucose and carbon atom \(2\) of fructose.
