Question

The basic building block of cellulose is

• A. Amino Acid
• B. Fatty Acid
• C. Glucose
• D. Nucleic acid

Hint:

Polysaccharide building blocks:
Cellulose $\rightarrow \beta$-D-Glucose.
Starch Glycogen $\rightarrow \alpha$-D-Glucose.
Inulin $\rightarrow$ Fructose.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Cellulose is a structural linear homopolysaccharide constituting the primary cell wall matrix in green plants.
Key Formula or Approach:
\[ (\text{C}_6\text{H}_{10}\text{O}_5)_n \quad \text{linked by } \beta\text{-(1,4)-glycosidic bonds} \]

Step 2: Detailed Explanation:
Cellulose is a high-molecular-weight linear polymer consisting of unbranched chains of thousands of repeating D-glucose units linked exclusively by \(\beta\)-(1$\rightarrow$4)-glycosidic bonds.
Complete enzymatic or acid hydrolysis of cellulose yields pure D-glucose (via the disaccharide cellobiose intermediate).

Step 3: Final Answer:
Hence, the basic building block of cellulose is Glucose, matching option (C).
