Amino acids synthesised in our body are

Options

A. Non-essential
B. Essential
C. Non-proteinaceous
D. Deaminated.

Answer

To answer the question "Amino acids synthesized in our body are," we need to understand the classification of amino acids based on their synthesis in the body.

### Step-by-Step Solution:

1. **Classification of Amino Acids**:
- Amino acids can be classified into two categories: essential and non-essential amino acids.
- Essential amino acids are those that cannot be synthesized by the body and must be obtained through diet.
- Non-essential amino acids are those that can be synthesized by the body.

2. **Essential Amino Acids**:
- There are 9 essential amino acids that must be supplied by the diet. These include:
- Methionine
- Lysine
- Phenylalanine
- Tryptophan
- Leucine
- Isoleucine
- Valine
- Threonine
- Histidine (sometimes considered essential for infants)

3. **Non-Essential Amino Acids**:
- The body can synthesize 11 non-essential amino acids, which do not need to be obtained from the diet. Some examples include:
- Aspartic acid
- Glutamic acid (also known as glutamate)
- Cysteine
- Proline
- Serine
- Alanine
- Tyrosine

4. **Conclusion**:
- Therefore, the amino acids synthesized in our body are classified as non-essential amino acids.

### Final Answer:
Amino acids synthesized in our body are **non-essential amino acids**.
