The enzyme that catalyse the changing of emulsified oils to fatty acids and glycerol is -

Options

A. Pepsin
B. Lipase
C. Amylase
D. Sucrose

Answer

To solve the question regarding which enzyme catalyzes the conversion of emulsified oils to fatty acids and glycerol, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Process of Digestion**:
- The digestion of fats begins with emulsification, which is the process of breaking down large fat globules into smaller ones. This is primarily facilitated by bile salts produced in the liver.

2. **Identifying the Role of Bile Salts**:
- Bile salts help in emulsifying fats, making them more accessible for enzymatic action. This is a crucial step before the actual digestion of fats can occur.

3. **Recognizing the Enzymes Involved**:
- After emulsification, the smaller fat globules are acted upon by specific enzymes. The primary enzyme responsible for the digestion of fats is called lipase.

4. **Understanding the Function of Lipase**:
- Lipase catalyzes the breakdown of emulsified fats into their constituent units, which are fatty acids and glycerol. This is the key reaction that transforms the emulsified oils into simpler molecules that can be absorbed by the body.

5. **Evaluating the Options**:
- Given the options provided:
- **Pepsin**: A protein-digesting enzyme, not involved in fat digestion.
- **Lipase**: The correct enzyme that acts on fats.
- **Amylase**: A starch-digesting enzyme, not involved in fat digestion.
- Therefore, the correct answer is **Lipase**.

### Final Answer:
The enzyme that catalyzes the changing of emulsified oils to fatty acids and glycerol is **Lipase**.
