Collagen which is the most abundant protein in the animal world is a

Options

A. Fibrous protein
B. Globular protein
C. Lipid
D. Carbohydrate

Answer

**Step-by-Step Solution:**

1. **Understanding Collagen**: Collagen is identified as the most abundant protein in the animal kingdom. It plays a crucial role in providing structural support to various tissues.

2. **Classifying Proteins**: Proteins can be classified into two main categories based on their structure:
- **Fibrous Proteins**: These proteins have elongated, thread-like structures. Examples include actin, myosin, and fibrinogen.
- **Globular Proteins**: These proteins are more spherical or globular in shape and are usually soluble in water.

3. **Identifying the Type of Collagen**: Collagen is not a fibrous protein; rather, it is classified as a globular protein. This classification is based on its molecular structure and solubility.

4. **Eliminating Incorrect Options**: The question also mentions lipids and carbohydrates as possible options. Since collagen is a protein, it cannot be classified as either a lipid or a carbohydrate.

5. **Conclusion**: Based on the classification of proteins and the characteristics of collagen, we conclude that collagen is a globular protein.

**Final Answer**: Collagen is a globular protein.
