The major fibrous protien of conncetive tissue is

Options

A. myosin
B. myoglobin
C. collage
D. keratin

Answer

### Step-by-Step Solution:

1. **Identify the Types of Proteins**: Proteins can be categorized based on their shape and solubility into two main types: fibrous proteins and globular proteins.

2. **Focus on Fibrous Proteins**: Since the question specifically asks for a fibrous protein found in connective tissues, we need to identify which proteins fall into this category. Examples of fibrous proteins include collagen, keratin, myosin, and myoglobin.

3. **Determine the Major Fibrous Protein in Connective Tissue**: Among the listed fibrous proteins, collagen is recognized as the most abundant protein in connective tissues. It serves as a major structural component in the extracellular matrix.

4. **List the Locations of Collagen**: Collagen is found in various parts of the body, including:
- Fibrous tissues such as ligaments and tendons
- Skin
- Cornea
- Cartilage
- Bone
- Blood vessels

5. **Discuss the Function of Collagen**: Collagen plays a crucial role in providing strength and structure to tissues. It is also involved in the aging process, as the production of collagen decreases with age.

6. **Eliminate Incorrect Options**:
- **Myosin**: A contractile protein found in muscles, not connective tissue.
- **Myoglobin**: A protein that stores oxygen in muscle cells, not related to connective tissue.
- **Keratin**: A fibrous protein found in hair, nails, and the outer layer of skin, but not primarily in connective tissue.

7. **Conclude with the Correct Answer**: The major fibrous protein of connective tissue is **collagen**.

### Final Answer:
The major fibrous protein of connective tissue is **collagen**.
