Blood cholesterol reducing agent is:

Options

A. Statins
B. lipase
C. protease
D. zymase

Answer

To solve the question "Blood cholesterol reducing agent is:", we will analyze the options provided and determine which one is correct based on their functions.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for an agent that reduces blood cholesterol levels. We need to identify which of the provided options serves this function.

2. **Analyzing Option 1: Statins**:
- Statins are a group of drugs specifically designed to lower cholesterol levels in the blood.
- They work by inhibiting an enzyme involved in cholesterol production in the liver, thereby reducing overall cholesterol levels.
- Statins are derived from filamentous fungi, which is an important aspect of their origin.
- **Conclusion**: Statins are indeed a blood cholesterol reducing agent.

3. **Analyzing Option 2: Lipase**:
- Lipase is an enzyme that breaks down fats (lipids) into fatty acids and glycerol.
- While it plays a role in fat metabolism, it does not directly reduce cholesterol levels in the blood.
- **Conclusion**: Lipase is not a cholesterol reducing agent.

4. **Analyzing Option 3: Protease**:
- Protease is an enzyme that breaks down proteins into smaller peptides or amino acids.
- It does not have any effect on cholesterol levels.
- **Conclusion**: Protease is not a cholesterol reducing agent.

5. **Analyzing Option 4: Zymase**:
- Zymase is a complex of enzymes that facilitates the fermentation process, converting sugars into ethanol and carbon dioxide.
- It is not involved in cholesterol metabolism.
- **Conclusion**: Zymase is not a cholesterol reducing agent.

6. **Final Conclusion**: After analyzing all the options, the only agent that effectively reduces blood cholesterol levels is **Statins**. Therefore, the correct answer is **Option 1**.
