The molecular weight of organic compounds found in acidinsoluble is

Options

A. one thousand Dalton
B. ten thousand Dalton
C. more than ten thousand Daltons
D. less than ten thousand Daltons

Answer

To determine the molecular weight of organic compounds found in the acid-insoluble pool, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Acid Fractionation**:
- Organic compounds can be separated into two pools based on their solubility in acid: the acid-soluble pool and the acid-insoluble pool.

2. **Identifying the Acid-Soluble Pool**:
- The acid-soluble pool contains organic compounds with molecular weights ranging from 18 to 800 Dalton.
- This pool includes smaller molecules such as amino acids and monosaccharides.

3. **Identifying the Acid-Insoluble Pool**:
- The acid-insoluble pool contains organic compounds with molecular weights greater than 10,000 Dalton.
- This pool includes larger biological macromolecules such as proteins, nucleic acids, carbohydrates, and lipids.

4. **Analyzing the Options**:
- Given the options:
- 1000 Dalton
- 10,000 Dalton
- More than 10,000 Dalton
- Less than 10,000 Dalton
- We can eliminate the first two options (1000 Dalton and 10,000 Dalton) as they do not fit the criteria for the acid-insoluble pool.

5. **Conclusion**:
- Since the acid-insoluble pool contains compounds with molecular weights greater than 10,000 Dalton, the correct answer is **more than 10,000 Dalton**.

### Final Answer:
The molecular weight of organic compounds found in the acid-insoluble pool is **more than 10,000 Dalton**.
