Which is correct about the bile?

Options

A. It is synthesized by gall bladder and also stored there
B. It is an enzyme which emulsifies the fats
C. It contain bile salts and bile pigments
D. Bilirubin present in it decomposes fats

Answer

**Step-by-Step Solution:**

1. **Understanding Bile**: Bile is a fluid produced by the liver that plays a crucial role in digestion, particularly in the emulsification of fats.

2. **Synthesis and Storage**: Bile is synthesized by the liver and stored in the gallbladder. This is an important distinction because some options may incorrectly state that bile is synthesized in the gallbladder.

3. **Composition of Bile**: Bile consists of various components, including:
- Bile salts
- Sodium carbonate
- Glycocholate and taurocholate (forms of bile salts)
- Bile pigments (bilirubin and biliverdin)
- Cholesterol
- Lecithin

4. **Function of Bile**: While bile contains bile salts that help emulsify fats, it does not contain digestive enzymes. This means that bile aids in the digestion of fats but does not directly break them down like enzymes do.

5. **Role of Bile Pigments**: The bile pigments, bilirubin and biliverdin, are primarily excretory substances and do not play a role in the digestion of fats.

6. **Evaluating Options**:
- The first option is incorrect as it states that bile is synthesized in the gallbladder.
- The second option is incorrect as it refers to bile as an enzyme, which it is not.
- The third option is correct as it states that bile contains bile salts and bile pigments.
- The fourth option is incorrect as it suggests that bilirubin decomposes fats, which it does not.

7. **Final Answer**: The correct statement about bile is that it contains bile salts and bile pigments.
