Question:
Which of the following is a non-reducing sugar?
Which of the following is a non-reducing sugar?
Show Hint
Non-reducing sugars, like sucrose, do not have a free aldehyde or ketone group and do not reduce other compounds.
Updated On: May 17, 2025
- Maltose
- Lactose
- Glucose
- Sucrose
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Sucrose is a non-reducing sugar because it does not have a free aldehyde or ketone group that can act as a reducing agent. It is formed by the combination of glucose and fructose through a glycosidic bond between their anomeric carbons. This bond prevents sucrose from participating in reducing reactions, unlike maltose and lactose, which are reducing sugars.

- Given below are two statements:
Statement I: Sucrose is dextrorotatory. However, sucrose upon hydrolysis gives a solution having mixture of products. This solution shows laevorotation.
Statement II: Hydrolysis of sucrose gives glucose and fructose. Since the laevorotation of glucose is more than the dextrorotation of fructose, the resulting solution becomes laevorotatory.
In the light of the above statements, choose the correct answer from the options given below.- JEE Main - 2026
