Interferon is a glycoprotein which is

Options

A. antibacterial
B. antifungal
C. antiviral
D. all of these

Answer

**Step-by-Step Solution:**

1. **Definition of Interferon**: Interferon is a type of glycoprotein. Glycoproteins are molecules that consist of a protein and a carbohydrate (sugar) component.

2. **Types of Interferons**: There are several types of interferons, including alpha, beta, and gamma. Each type has specific roles in the immune response.

3. **Nature of Glycoproteins**: Glycoproteins are formed when carbohydrate residues are attached to proteins. This structure is significant for their function in biological processes.

4. **Role of Interferon**: Interferons are secreted by cells that have been infected by viruses. They serve as signaling molecules that alert neighboring cells to the presence of a virus, helping to protect them.

5. **Functionality of Interferon**: Interferons are known for their antiviral properties. They help to inhibit viral replication and spread, making them crucial in the body's defense against viral infections.

6. **Options Analysis**: The question provides options: antibacterial, antifungal, antiviral, and all of these. Given that interferons primarily function to combat viral infections, the correct classification of interferon is "antiviral."

7. **Conclusion**: Therefore, the correct answer to the question is option C: antiviral.
