Options

A. 20
B. 10
C. 5
D. 14

Answer

To solve the question about the number of amino acids that the human body can synthesize, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Total Number of Amino Acids**:
- There are a total of 20 standard amino acids that are used to build proteins.

2. **Differentiate Between Essential and Non-Essential Amino Acids**:
- Amino acids are categorized into two groups:
- **Essential Amino Acids**: These cannot be synthesized by the human body and must be obtained from the diet.
- **Non-Essential Amino Acids**: These can be synthesized by the human body.

3. **Identify the Number of Non-Essential Amino Acids**:
- Among the 20 amino acids, the human body can synthesize 10 of them. These are the non-essential amino acids.

4. **Conclusion**:
- Therefore, the number of amino acids that the human body can synthesize is **10**.

### Final Answer:
The number of amino acids found in proteins that a human body can synthesize is **10**.
