An example of fibrous protein is :

Options

A. albumin
B. globulin
C. collagen
D. prolamine

Explanation

To determine an example of a fibrous protein, we will follow these steps:

### Step 1: Understand what fibrous proteins are
Fibrous proteins, also known as structural proteins, are proteins that have elongated, fibrous structures. They are typically insoluble in water and provide support, strength, and elasticity to various tissues in the body.

**Hint:** Remember that fibrous proteins are structural and often found in connective tissues.

### Step 2: Identify where fibrous proteins are found
Fibrous proteins are primarily found in structures such as bones, cartilage, and connective tissues. They play a crucial role in maintaining the integrity and strength of these structures.

**Hint:** Think about the roles of proteins in the body and where they are most needed.

### Step 3: Look for examples of fibrous proteins
Common examples of fibrous proteins include:
- Collagen: Found in skin, bones, and connective tissues.
- Keratin: Found in hair, nails, and the outer layer of skin.
- Elastin: Provides elasticity to tissues.

**Hint:** Focus on proteins that provide structure and support.

### Step 4: Analyze the options given
Now, let’s analyze the options provided:
1. Albumin: This is a globular protein, not fibrous.
2. Globulin: Also a globular protein, involved in various biological functions.
3. Collagen: This is a fibrous protein, known for its structural role in tissues.
4. Prolamine: A storage protein found in plants, not fibrous.

**Hint:** Eliminate options that are not structural proteins.

### Step 5: Choose the correct answer
Based on the analysis, the correct answer is **Collagen**, as it is a well-known example of a fibrous protein.

**Final Answer:** An example of fibrous protein is **Collagen**.
