Question

Which of the following amino acids are synthesized in our body?

• A. Proline
• B. Valine
• C. Histidine
• D. Arginine

Hint:

Remember that while some amino acids are non-essential and can be synthesized by the body, others are essential and must come from the diet.

Answer 1

The Correct Option is D

Amino acids are classified as essential and non-essential. Essential amino acids cannot be synthesized by the human body and must be obtained through diet. Non-essential amino acids, on the other hand, can be synthesized by the body. Among the options: - Proline: This is a non-essential amino acid that is synthesized in the body. - Valine: This is an essential amino acid and must be obtained through the diet. - Histidine: This is an essential amino acid for infants but is non-essential for adults as it can be synthesized in the body. - Arginine: This is a conditionally essential amino acid. It is non-essential in healthy adults but essential in infants and during periods of stress or illness. - Leucine: This is an essential amino acid and must be obtained from the diet. Thus, Arginine is the correct answer as it is conditionally essential.
