Question:
Observe the following amino acids:
Observe the following amino acids:
Show Hint
Essential amino acids cannot be synthesized by the body and must be obtained through diet. Non-essential amino acids, like serine, can be synthesized internally.
Updated On: Mar 25, 2025
- Both I, II are essential amino acids
- Both I, II are non-essential amino acids
- I is essential amino acid, II is non-essential amino acid
- I is non-essential amino acid, II is essential amino acid
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
1. Amino Acid I (Left Structure): The structure represents Leucine, which has a branched hydrocarbon side chain. Leucine is an essential amino acid, meaning it must be obtained from the diet.
2. Amino Acid II (Right Structure): The structure represents Serine, which contains a hydroxyl (-OH) group. Serine is a non-essential amino acid, meaning the body can synthesize it.
Thus, Amino Acid I (Leucine) is essential, and Amino Acid II (Serine) is non-essential, making option (3) the correct choice.
2. Amino Acid II (Right Structure): The structure represents Serine, which contains a hydroxyl (-OH) group. Serine is a non-essential amino acid, meaning the body can synthesize it.
Thus, Amino Acid I (Leucine) is essential, and Amino Acid II (Serine) is non-essential, making option (3) the correct choice.
