In human body, the role of bile salts in digestion is to

Options

A. act as co-enzymes during the digestion of carbohydrates
B. emulsify fats and facilitate their absorption.
C. aid in the break-up of proteins into amino acids and their absorption
D. stimulate the pancreas to release it enzymes

Answer

**Step-by-Step Solution:**

1. **Understanding Bile Salts**: Bile salts are components of bile, a fluid produced by the liver and stored in the gallbladder. They play a crucial role in the digestion and absorption of fats.

2. **Role in Digestion**: The primary function of bile salts is to emulsify fats. Emulsification is the process of breaking down large fat globules into smaller droplets, which increases the surface area for digestive enzymes to act upon.

3. **Facilitation of Absorption**: After emulsification, bile salts also help in the absorption of the resulting fatty acids and monoglycerides in the small intestine. They form micelles, which transport these lipids to the intestinal epithelial cells for absorption.

4. **Comparison with Other Digestive Processes**: It is important to note that bile salts do not act as coenzymes in carbohydrate digestion, nor do they directly aid in the breakdown of proteins or stimulate the pancreas. Other enzymes such as amylase, proteases, and hormones like gastrin are responsible for these processes.

5. **Conclusion**: Therefore, the correct answer to the question is that bile salts in the human body primarily function to emulsify fats and facilitate their absorption in the digestive system.

**Final Answer**: Bile salts in the human body play the role of emulsifying fats and facilitating their absorption.
