Question

The number of essential and non-essential amino acids from the following list respectively is Given amino acids: Val, Gly, Leu, Lys, Pro, Ser

• A. \( 5, 1 \)
• B. \( 4, 2 \)
• C. \( 2, 4 \)
• D. \( 3, 3 \)

Hint:

Essential amino acids cannot be synthesized by the human body and must be obtained from the diet. Non-essential amino acids can be produced by the body from other compounds.

Answer 1

The Correct Option is D

Step 1: Classification of amino acids
Amino acids are categorized into:
- Essential amino acids: Must be obtained from the diet as the body cannot synthesize them.
- Non-essential amino acids: Can be synthesized by the body.
Step 2: Identifying essential and non-essential amino acids in the given list
- Essential amino acids:
- Valine (Val) - Essential
- Leucine (Leu) - Essential
- Lysine (Lys) - Essential
- Non-essential amino acids:
- Glycine (Gly) - Non-essential
- Proline (Pro) - Non-essential
- Serine (Ser) - Non-essential
Step 3: Conclusion From the given list, there are 3 essential amino acids (Val, Leu, Lys) and 3 non-essential amino acids (Gly, Pro, Ser). Thus, the correct answer is (3,3).
