Explanation

To solve the question regarding the hydrolysis products of salmine and its common name, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Salmine**:
- Salmine is a polypeptide derived from salmon, specifically from the sperm of salmon fish. It consists of various amino acids.

2. **Identifying Amino Acids**:
- The hydrolysis products listed include:
- Isoleucine: 1.31 g
- Alanine: 0.89 g
- Serine: 7.35 g
- Arginine: 86.40 g
- Valine: 3.51 g
- Glycine: 3.0 g
- Proline: 6.90 g

3. **Molecular Weights of Amino Acids**:
- The molecular weights provided are:
- Isoleucine: 131 g/mol
- Alanine: 89 g/mol
- Serine: 105 g/mol
- Arginine: 174 g/mol
- Valine: 117 g/mol
- Glycine: 75 g/mol
- Proline: 115 g/mol

4. **Common Name of Salmine**:
- Salmine is commonly known as **protamine**.
- When in its sulfate form, it is referred to as **protamine sulfate**.

5. **Conclusion**:
- The question asks for what salmine is also known as. The correct answer is **protamine**. If both options (protamine and protamine sulfate) are available, both can be considered correct, but protamine is the more direct answer.

### Final Answer:
Salmine is also known as **protamine** (and in its sulfate form, **protamine sulfate**).
