Explanation

To determine the name of salmine, we need to analyze the information provided about its amino acid composition and molecular weight. Here's a step-by-step breakdown of how to arrive at the answer:

### Step 1: Identify the Source of Salmine
Salmine is a polypeptide derived from salmon, specifically from the sperm of the salmon fish. This is important as it gives context to the name.

**Hint:** Remember that many proteins and polypeptides are named after their source or function.

### Step 2: List the Amino Acids Present
From the hydrolysis products, we have the following amino acids and their respective weights:
- 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

**Hint:** Make sure to note the weights as they can indicate the abundance of each amino acid in the polypeptide.

### Step 3: Determine the Molecular Weights of the Amino Acids
The molecular weights of the amino acids are provided:
- 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

**Hint:** Knowing the molecular weights helps in understanding the composition and structure of the polypeptide.

### Step 4: Calculate the Total Molecular Weight of Salmine
The total molecular weight of salmine is given as 10,966 g/mol. This can be used to verify the composition if needed.

**Hint:** The total weight can be calculated by summing the contributions of each amino acid based on their weights and molecular weights.

### Step 5: Identify the Common Name for Salmine
Salmine is known to be a type of protein found in salmon. Specifically, it is often referred to as "salmine" which is derived from the Latin word for salmon.

**Hint:** Consider the naming conventions in biochemistry, where proteins are often named after their source or function.

### Conclusion
Based on the analysis, salmine is known as "salmine" and is derived from salmon.

### Final Answer
Salmine is also known as "salmine," a polypeptide obtained from the sperm of salmon fish.
