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

An essential amino acid is one that cannot be synthesized by the body and must be obtained from the diet.

• Valine is an essential amino acid, meaning the body cannot produce it, and it must be obtained through food.
• Glycine and Alanine are non-essential amino acids, as the body can synthesize them.
• Serine is also a non-essential amino acid, as it can be synthesized by the body.

Thus, the correct answer is Option C: Valine.
