An example of conjugated protein is :

Options

A. albumin
B. haemoglobin
C. phosphoprotein
D. myoglobin

Explanation

To determine an example of a conjugated protein, we first need to understand what conjugated proteins are.

### Step-by-Step Solution:

1. **Definition of Conjugated Proteins**:
- Conjugated proteins are proteins that are combined with non-polypeptide components. These non-polypeptide components can include carbohydrates, lipids, or phosphate groups.

2. **Types of Conjugated Proteins**:
- **Glycoproteins**: These are proteins that have carbohydrate groups attached to them.
- **Phosphoproteins**: These contain phosphate groups attached to the protein.
- **Lipoproteins**: These are proteins that have lipid molecules attached.

3. **Analyzing the Options**:
- **Option A: Albumin**: This is a simple protein produced in the liver and does not contain any non-polypeptide components. Therefore, it is not a conjugated protein.
- **Option B: Hemoglobin**: This is a quaternary protein found in red blood cells, responsible for oxygen transport. It is not classified as a conjugated protein.
- **Option C: Phosphoprotein**: This is a conjugated protein because it contains phosphate groups attached to the protein structure.
- **Option D: Myoglobin**: Similar to hemoglobin, myoglobin is a simple protein found in muscle tissue and does not have any non-polypeptide components.

4. **Conclusion**:
- Among the given options, the only example of a conjugated protein is **Option C: Phosphoprotein**.

### Final Answer:
The example of a conjugated protein is **Phosphoprotein**.
