Microfibrils are composed of

Options

A. Hemicellulose
B. Cellulose
C. Peptidoglycans
D. lignin

Answer

**Step-by-Step Solution:**

1. **Understanding Microfibrils**: Microfibrils are fine, thread-like structures found in the cell. They play a crucial role in providing structural support.

2. **Composition of Microfibrils**: Microfibrils are primarily composed of glycoproteins and polysaccharides. The polysaccharides are made up of linear chains of glucose units.

3. **Identifying the Main Component**: The main polysaccharide component in microfibrils is cellulose, which consists of many beta-linked glucose units.

4. **Differentiating Components**: While cellulose is a significant component, microfibrils also contain hemicellulose, which is a complex carbohydrate that includes various sugars and is associated with cellulose.

5. **Conclusion**: Therefore, microfibrils are primarily composed of hemicellulose, along with glycoproteins and cellulose.

6. **Final Answer**: The correct answer to the question is hemicellulose.
