Monomers of which one of the following biodegradable polymer are amino acids

Options

A. polyglycolic acids
B. PHBV
C. Nylon-6
D. Nylon-2-Nylon-6

Answer

To determine which biodegradable polymer has amino acids as its monomers, we will analyze each of the given options step by step.

### Step 1: Identify the polymers and their monomers
1. **Polyglycolic Acid**: This polymer is made from glycolic acid, which is not an amino acid.
2. **PHBV (Poly β-hydroxybutyrate-co-β-hydroxyvalerate)**: This polymer is synthesized from 3-hydroxybutyric acid and 3-hydroxypentanoic acid, neither of which are amino acids.
3. **Nylon 6**: The monomer for nylon 6 is caprolactam, which is also not an amino acid.
4. **Nylon 2 Nylon 6**: This polymer is produced from glycine and amino caproic acid. Glycine is an amino acid, and amino caproic acid is a derivative of glycine.

### Step 2: Analyze the options
- **Polyglycolic Acid**: Not made from amino acids.
- **PHBV**: Not made from amino acids.
- **Nylon 6**: Not made from amino acids.
- **Nylon 2 Nylon 6**: Made from glycine (an amino acid) and amino caproic acid (an analog of glycine).

### Step 3: Conclusion
Based on the analysis, the biodegradable polymer whose monomers are amino acids is **Nylon 2 Nylon 6**.

### Final Answer
The correct answer is **Nylon 2 Nylon 6**.
