Question:
The incorrect statement in the following is:
The incorrect statement in the following is:
Show Hint
Remember: Cellulose uses $\beta$-linkages (beta-cellulose); Starch uses $\alpha$-linkages.
Updated On: Jun 3, 2026
- Amylopectin has $C_{1}-C_{4}$ and $C_{1}-C_{6}$ glycosidic linkages
- Cellulose is a straight chain polysaccharide of $\alpha-D$-glucose units through $C_{1}-C_{4}$ glycosidic linkage
- Glycogen is found in Yeast and fungi
- Glycogen is also known as animal starch
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Polysaccharides are structural or storage carbohydrates consisting of glucose units linked by glycosidic bonds.
Step 2: Meaning
Cellulose is composed of $\beta-D$-glucose units, not $\alpha-D$-glucose units.
Step 3: Analysis
Amylopectin is branched and contains both $C_{1}-C_{4}$ and $C_{1}-C_{6}$ linkages (True). Glycogen is indeed found in fungi/yeast and is known as animal starch (True). Cellulose is made of $\beta-D$-glucose (False).
Step 4: Conclusion
The statement identifying cellulose as a polymer of $\alpha-D$-glucose is the incorrect one.
Final Answer: (B)
