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

Amino acids are categorized into essential and non-essential types. Essential amino acids cannot be synthesized by the body and must be obtained through the diet. Non-essential amino acids can be synthesized by the human body.

Given amino acids: Val, Gly, Leu, Lys, Pro, Ser.

Let's classify each:

• Valine (Val): Essential
• Glycine (Gly): Non-essential
• Leucine (Leu): Essential
• Lysine (Lys): Essential
• Proline (Pro): Non-essential
• Serine (Ser): Non-essential

From the list, the essential amino acids are Val, Leu, and Lys. The non-essential amino acids are Gly, Pro, and Ser. Therefore, there are 3 essential and 3 non-essential amino acids.

Amino Acid	Type
Val	Essential
Gly	Non-essential
Leu	Essential
Lys	Essential
Pro	Non-essential
Ser	Non-essential

Thus, the number of essential and non-essential amino acids is \(3\) and \(3\) respectively.

Answer 2

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).
