Which ones are bile salts?

Options

A. Haemglobin and biliverdin
B. Bilirubin and biliverdin
C. Bilirubin and haemoglobin
D. Sodium glycolate and taurocholate

Answer

To determine which options are bile salts, we can follow these steps:

### Step 1: Understand what bile salts are
Bile salts are derived from bile acids, which are synthesized from cholesterol in the liver. They play a crucial role in the digestion and absorption of fats. Bile salts are formed when bile acids combine with amino acids, specifically glycine or taurine.

### Step 2: Identify the components of bile salts
The primary bile acids include:
1. Cholic acid
2. Deoxycholic acid
3. Chenodeoxycholic acid
4. Lithocholic acid

These bile acids can conjugate with glycine or taurine to form bile salts.

### Step 3: Analyze the options provided
1. **Hemoglobin and Bilirubin**: Hemoglobin is a respiratory pigment, and bilirubin is a bile pigment. Neither of these is a bile salt.
2. **Bilirubin and Bilirubin**: Both are bile pigments, not bile salts.
3. **Bilirubin and Hemoglobin**: Again, both are pigments, not bile salts.
4. **Sodium Glycolate and Taurocholate**: These are the conjugated forms of bile acids with glycine (sodium glycolate) and taurine (taurocholate). Therefore, they are indeed bile salts.

### Step 4: Conclusion
Based on the analysis, the correct answer is that the bile salts are **Sodium Glycolate and Taurocholate**.
