Question:
Complete hydrolysis of cellulose gives:
Complete hydrolysis of cellulose gives:
Show Hint
Cellulose is a polysaccharide made of D-glucose units, and its hydrolysis results in D-glucose.
Updated On: Apr 22, 2026
- D-fructose
- D-ribose
- D-glucose
- L-glucose
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understand the structure of cellulose.
Cellulose is a polymer of glucose, where glucose molecules are linked by \( \beta \)-1,4-glycosidic bonds. When cellulose undergoes complete hydrolysis, the \( \beta \)-glycosidic bonds are broken, and the resulting product is D-glucose.
Step 2: Analyze the options.
- (1) D-fructose: This is a monosaccharide that does not result from the hydrolysis of cellulose.
- (2) D-ribose: This is a pentose sugar and is not a product of cellulose hydrolysis.
- (3) D-glucose: This is the correct product, as cellulose is made up of glucose units, and hydrolysis breaks it down into D-glucose. - (4) L-glucose: This is the enantiomer of D-glucose and would not be produced by hydrolysis of cellulose.
Step 3: Conclusion.
The correct answer is (3), D-glucose, as it is the product of complete hydrolysis of cellulose.
