Gastric juice does not contain

Options

A. Lipase
B. Rennin
C. Protease
D. Amylase

Answer

To determine which component is not present in gastric juice, we need to analyze the components that are typically found in gastric juice and compare them with the options provided.

### Step-by-Step Solution:

1. **Understanding Gastric Juice**: Gastric juice is a digestive fluid produced by the stomach lining. It primarily contains hydrochloric acid, pepsinogen (which is converted to pepsin), and intrinsic factor, among other substances.

2. **Identifying the Components**:
- **Lipase**: This is an enzyme that breaks down fats. It is primarily produced by the pancreas and is not a significant component of gastric juice.
- **Rennin (or Ranin)**: This enzyme is involved in the coagulation of milk and is present in gastric juice, especially in infants.
- **Protease**: This is a general term for enzymes that break down proteins. Pepsin, a type of protease, is present in gastric juice.
- **Amylase**: This enzyme breaks down carbohydrates. It is primarily produced in the saliva and pancreas, and is not found in significant amounts in gastric juice.

3. **Comparing Options**:
- Lipase: Not present in significant amounts in gastric juice.
- Rennin: Present in gastric juice.
- Protease: Present in gastric juice (as pepsin).
- Amylase: Not present in gastric juice.

4. **Conclusion**: Among the options provided, **Lipase** is the component that is not present in gastric juice.

### Final Answer:
Gastric juice does not contain **Lipase**.
