What is the function of bile salt in the intestine?

Options

A. Activator of lipase
B. Emulsifier
C. Co factor of cholesteryl esterase
D. Inhibitor of lipid absorption

Explanation

### Step-by-Step Solution:

1. **Understanding Bile Salts**: Bile salts are compounds that are derived from cholesterol and are produced in the liver. They are stored in the gallbladder and released into the intestine during digestion.

2. **Role in Digestion**: The primary function of bile salts in the intestine is to aid in the digestion of fats. They help to emulsify large fat globules into smaller droplets, which increases the surface area for digestive enzymes to act upon.

3. **Emulsification Process**: Emulsification is the process by which bile salts break down large fat globules into smaller ones. This is crucial because enzymes like lipase can only act on the surface of fat droplets. By increasing the surface area, bile salts facilitate more efficient digestion of fats.

4. **Additional Functions**: Besides emulsification, bile salts also serve other roles:
- They act as emulsifiers, helping to stabilize the mixture of fat and water in the intestine.
- They can act as co-factors for cholesterol absorption.
- They may inhibit lipid absorption to some extent, regulating the amount of fat that enters the bloodstream.

5. **Conclusion**: In summary, bile salts play a critical role in the digestion of fats by emulsifying them, which allows for better enzymatic action and absorption in the intestine.
