The absorption of which of the following does not occur in stomach?

Options

A. Simple sugars
B. Alcohol
C. Water
D. Amino acids

Answer

To determine which substance is not absorbed in the stomach, we will analyze the absorption of each option provided: simple sugars, alcohol, water, and amino acids.

### Step-by-Step Solution:

1. **Understanding Absorption in the Stomach**:
- The stomach primarily functions in the mechanical and chemical breakdown of food. While some absorption does occur, it is limited compared to the small intestine.

2. **Analyzing Each Option**:
- **Simple Sugars**:
- Simple sugars (like glucose) undergo digestion primarily in the small intestine. They are not significantly absorbed in the stomach.

- **Alcohol**:
- Alcohol is absorbed in the stomach and small intestine. It can pass through the stomach lining into the bloodstream relatively easily.

- **Water**:
- Water is absorbed in various parts of the digestive system, including the stomach. The stomach can absorb some water, although most absorption occurs in the small and large intestines.

- **Amino Acids**:
- Amino acids are the building blocks of proteins and are primarily absorbed in the small intestine. They are not absorbed in significant amounts in the stomach.

3. **Conclusion**:
- Based on the analysis, the substance that is not absorbed in the stomach is **Amino Acids**. They are absorbed mainly in the small intestine.

### Final Answer:
The absorption of **Amino Acids** does not occur in the stomach.
