D. not repuired for portein synthesis

Answer

### Step-by-Step Solution:

1. **Definition of Non-Essential Amino Acids**: Non-essential amino acids are those that our body can synthesize on its own. This means that they are not required to be obtained from dietary sources.

2. **Synthesis in the Body**: Unlike essential amino acids, which must be consumed through food, non-essential amino acids are produced by the body through various metabolic processes.

3. **Examples of Non-Essential Amino Acids**: Some common non-essential amino acids include:
- Alanine
- Arginine
- Aspartic acid
- Glutamine
- Glycine
- Proline

4. **Importance of Non-Essential Amino Acids**: While they are not required in the diet, non-essential amino acids still play important roles in various physiological functions and protein synthesis within the body.

5. **Conclusion**: Therefore, non-essential amino acids are those that are synthesized by the body and do not need to be included in the diet for growth and development.
