Question:
Which of the following statement is correct?
Which of the following statement is correct?
Show Hint
In disaccharides like sucrose, the linkage between sugar units determines whether it is reducing or non-reducing.
Updated On: Mar 7, 2025
- Sucrose is laevorotatory.
- Fructose is a disaccharide.
- Sucrose on hydrolysis gives D(+) glucose only.
- Sucrose is made up of a glycosidic linkage between C1 of $\alpha$-D-glucose and C2 of $\beta$-D-Fructose.
- Sucrose is a reducing sugar.
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Sucrose is a disaccharide consisting of one molecule of glucose and one molecule of fructose.
Step 2: Sucrose is formed by a glycosidic linkage between C1 of $\alpha$-D-glucose and C2 of $\beta$-D-fructose.
Step 3: This linkage makes sucrose non-reducing because both glucose and fructose are in their non-reducing forms.
Step 2: Sucrose is formed by a glycosidic linkage between C1 of $\alpha$-D-glucose and C2 of $\beta$-D-fructose.
Step 3: This linkage makes sucrose non-reducing because both glucose and fructose are in their non-reducing forms.
