Simple storage protein that coagulates upon heating but remains soluble in dilute salt solution is correctly exempliied by

Options

A. globilin
B. albumin
C. histone
D. collagen

Answer

To solve the question about which simple storage protein coagulates upon heating but remains soluble in dilute salt solution, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- Coagulation refers to the process where a liquid protein changes from a liquid state to a semi-solid state when heat is applied.
- Solubility in dilute salt solution means that the protein can dissolve in a solution with a low concentration of salt.

2. **Identify the Types of Proteins**:
- There are different types of proteins, including globulins, albumins, histones, and collagen.
- Globular proteins are generally soluble in water and can be categorized based on their solubility.

3. **Analyze the Characteristics of Each Protein**:
- **Albumins**: Soluble in water and coagulate upon heating.
- **Globulins**: Generally insoluble in water but can become soluble in dilute salt solutions.
- **Histones**: Soluble in water but not typically classified as storage proteins.
- **Collagen**: Not a storage protein and does not fit the criteria.

4. **Focus on the Coagulation and Solubility**:
- We need a protein that coagulates when heated and remains soluble in dilute salt solutions.
- Globulins fit this description as they are insoluble in pure water but can dissolve in salt solutions like sodium chloride, and they coagulate upon heating due to denaturation.

5. **Conclusion**:
- Based on the analysis, the correct answer is **Globulin**.

### Final Answer:
The simple storage protein that coagulates upon heating but remains soluble in dilute salt solution is correctly exemplified by **Globulin**.
