Question

Which among the following is an essential amino acid?

• A. Glycine
• B. Alanine
• C. Valine
• D. Serine

Answer 1

The Correct Option is C

The task is to select an essential amino acid from the provided list. Essential amino acids are those that the human body cannot produce and must be acquired through dietary intake. The following analysis clarifies the essentiality of each listed amino acid:

• Glycine: Classified as a non-essential amino acid, it can be synthesized internally by the human body.
• Alanine: Similarly, this is a non-essential amino acid, also synthesized by the body.
• Valine: This is an essential amino acid, requiring dietary consumption as the body lacks the capability to synthesize it. Its functions include crucial roles in muscle metabolism and tissue repair.
• Serine: This is a non-essential amino acid, produced by the body from other metabolic compounds.

Consequently, Valine is identified as the correct answer due to its classification as an essential amino acid.
