Which of the following is abosrbed in the stomach?

Options

A. Fatty acid
B. Amino acid
C. Drugs
D. Simple sugars

Answer

To determine which substance is absorbed in the stomach, we need to analyze each of the given options based on their properties and the conditions present in the stomach.

### Step-by-Step Solution:

1. **Identify the Options**: The options provided are fatty acids, amino acids, drugs, and simple sugars.

2. **Analyze Fatty Acids**:
- Fatty acids are components of lipids and fats.
- They are not easily dissolved in the stomach due to their complex structure.
- Lipids require specific enzymes for breakdown, which are primarily found in the small intestine.
- **Conclusion**: Fatty acids are not absorbed in the stomach.

3. **Analyze Amino Acids**:
- Amino acids are the building blocks of proteins.
- Proteins are large molecules and require extensive breakdown before absorption.
- The digestion of proteins primarily occurs in the stomach and small intestine, but amino acids themselves are not absorbed in the stomach.
- **Conclusion**: Amino acids are not absorbed in the stomach.

4. **Analyze Drugs**:
- Drugs can vary widely in their chemical structure and absorption characteristics.
- Many drugs are absorbed in the small intestine rather than the stomach.
- The acidic environment of the stomach (due to hydrochloric acid) can affect the solubility and absorption of certain drugs.
- **Conclusion**: Drugs are not typically absorbed in the stomach.

5. **Analyze Simple Sugars**:
- Simple sugars, such as monosaccharides (e.g., glucose) and disaccharides (e.g., sucrose), are small and easily soluble.
- The stomach has enzymes that can begin the digestion of carbohydrates.
- Simple sugars can be absorbed directly through the stomach lining into the bloodstream.
- **Conclusion**: Simple sugars are absorbed in the stomach.

6. **Final Answer**: Based on the analysis, the correct answer is **simple sugars**.
