From______acid, more than 17 amino acids are formed through transamination

Options

A. aspartic
B. glutamic
C. acetic
D. pyruvic

Explanation

To solve the question "From ______ acid, more than 17 amino acids are formed through transamination," we can follow these steps:

### Step-by-Step Solution:

1. **Understand Transamination**: Transamination is a biochemical process where an amino group from an amino acid is transferred to a keto acid. This process is crucial for the synthesis of amino acids in the body.

2. **Identify Key Acids**: The question asks for an acid that can lead to the formation of more than 17 amino acids. The two main acids involved in this process are glutamic acid and oxaloacetic acid.

3. **Focus on Glutamic Acid**: Among the acids involved, glutamic acid is particularly significant. It serves as a key amino donor in transamination reactions.

4. **Confirm the Number of Amino Acids**: It is known that from glutamic acid, more than 17 different amino acids can be synthesized through transamination. This includes amino acids like alanine, aspartate, and many others.

5. **Conclude the Answer**: Therefore, the correct answer to the question is "glutamic acid."

### Final Answer:
From **glutamic acid**, more than 17 amino acids are formed through transamination.
