Question

Which of the following statement is correct?

• A. Sucrose is laevorotatory.
• B. Fructose is a disaccharide.
• C. Sucrose on hydrolysis gives D(+) glucose only.
• D. Sucrose is made up of a glycosidic linkage between C1 of $\alpha$-D-glucose and C2 of $\beta$-D-Fructose.
• E. Sucrose is a reducing sugar.

Hint:

In disaccharides like sucrose, the linkage between sugar units determines whether it is reducing or non-reducing.

Answer 1

The Correct Option is D

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.
