Which process involves formation of non essential amino acid from keto acid ?
**Core Concept**
The process in question involves the synthesis of non-essential amino acids from keto acids, which is a key aspect of amino acid metabolism. This process is crucial for the production of amino acids that can be synthesized by the human body. **Amino acid synthesis** and **keto acid** metabolism are fundamental concepts in biochemistry.
**Why the Correct Answer is Right**
The correct answer involves the process of transamination, where an amino group is transferred from an amino acid to a keto acid, resulting in the formation of a new amino acid. This process is catalyzed by the enzyme **transaminase**, which plays a crucial role in the synthesis of non-essential amino acids. The **keto acid** acts as an acceptor of the amino group, and the resulting amino acid is a non-essential one.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not involve the formation of a non-essential amino acid from a keto acid.
**Option B:** This option is also incorrect as it involves a different biochemical process.
**Option C:** This option is incorrect because it is not related to amino acid synthesis from keto acids.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that **transamination** is a critical process for the synthesis of non-essential amino acids, and **keto acids** play a central role in this process. This concept is essential for understanding amino acid metabolism and its clinical implications.
**Correct Answer:** D. Transamination.
