Bile salts are

Options

A. Sodium bicarbonate and sodium taurocholate
B. Sodium glycocholate and sodium carbonate
C. Inorgains salts and sodium glycocholate
D. Sodium glycocholate and sodium taurocholate

Answer

### Step-by-Step Solution:

1. **Understanding Bile and Its Components**:
- Bile is a digestive fluid produced by the liver, stored in the gallbladder, and released into the duodenum (small intestine). It plays a crucial role in the emulsification of fats.

2. **Chemical Composition of Bile**:
- Bile is composed of several components:
- **Water**: Approximately 97-98%
- **Bile Pigments**: Such as bilirubin and biliverdin (around 0.2%)
- **Bile Salts**: Important for fat digestion (approximately 0.7%)
- **Fats**: Including cholesterol, fatty acids, and lecithin (around 0.51%)

3. **Identifying Bile Salts**:
- The main bile salts include:
- **Cholic Acid**
- **Glycocholic Acid**
- **Taurocholic Acid**
- These bile acids are conjugated with sodium to form bile salts, specifically:
- **Sodium Glycocholate**
- **Sodium Taurocholate**

4. **Analyzing the Options**:
- The question provides four options regarding the composition of bile salts:
- **A**: Sodium bicarbonate and sodium taurocholate
- **B**: Sodium glycolate and sodium carbonate
- **C**: Inorganic salts and sodium glycolate
- **D**: Sodium glycolate and sodium taurocholate
- Evaluating these options:
- **Option A**: Incorrect because sodium bicarbonate is not a bile salt.
- **Option B**: Incorrect because sodium carbonate is not a bile salt.
- **Option C**: Incorrect because inorganic salts are not bile salts.
- **Option D**: Correct because both sodium glycolate (glycocholate) and sodium taurocholate are indeed bile salts.

5. **Conclusion**:
- The correct answer is **Option D: Sodium Glycocholate and Sodium Taurocholate**.
