A good source of lipase is

Options

A. Saliva
B. Pancreatic juice
C. Bile
D. Gastric juice

Answer

To determine a good source of lipase, we need to analyze the options provided: saliva, pancreatic juice, bile, and gastric juice.

### Step-by-Step Solution:

1. **Understanding Lipase**:
- Lipase is an enzyme that catalyzes the hydrolysis of fats (lipids) into fatty acids and glycerol. It plays a crucial role in fat digestion.

2. **Evaluating the Sources**:
- **Saliva**: Contains the enzyme alpha-amylase, which is responsible for starch digestion, not lipase. Therefore, it is not a significant source of lipase.
- **Pancreatic Juice**: This is secreted by the pancreas and is rich in digestive enzymes, including a substantial amount of lipase. It is the primary source of lipase in the digestive system.
- **Bile**: Bile is produced by the liver and stored in the gallbladder. It aids in the emulsification of fats but does not contain any digestive enzymes, including lipase.
- **Gastric Juice**: Contains enzymes such as pepsin and gastric lipase, but the amount of gastric lipase is relatively small compared to that found in pancreatic juice.

3. **Conclusion**:
- Among the options, pancreatic juice is the best source of lipase due to its high concentration of this enzyme, making it the correct answer.

### Final Answer:
A good source of lipase is **pancreatic juice**.
