Question

Match List-I with List-II:

List-I (Amino Acid)	List-II (Nature of Amino Acid)
(A) Valine	(I) Basic amino acid
(B) Glycine	(II) Neutral optically active amino acid
(C) Lysine	(III) Acidic amino acid
(D) Glutamic acid	(IV) Neutral optically inactive amino acid

Choose the correct answer from the options given below:

• (A) - (I), (B) - (III), (C) - (II), (D) - (IV)
• (A) - (I), (B) - (II), (C) - (III), (D) - (IV)
• (A) - (I), (B) - (III), (C) - (IV), (D) - (II)
• (A) - (II), (B) - (IV), (C) - (I), (D) - (III)

Answer 1

The Correct Option is D

To correctly pair Amino Acids (List-I) with their Nature (List-II), understanding each amino acid's characteristics is essential.

1. Valine: A neutral, optically active, essential amino acid with a branched-chain structure.
2. Glycine: The most basic amino acid; its side chain is a hydrogen atom, rendering it neutral and optically inactive.
3. Lysine: Characterized by a long side chain terminating in an amine group, classifying it as a basic amino acid.
4. Glutamic Acid: Possesses acidic properties due to its carboxyl-containing side chain.

These properties facilitate the matching of each amino acid to its correct nature:

List-I (Amino Acid)	List-II (Nature of Amino Acid)
(A) Valine	(II) Neutral optically active amino acid
(B) Glycine	(IV) Neutral optically inactive amino acid
(C) Lysine	(I) Basic amino acid
(D) Glutamic acid	(III) Acidic amino acid

The matches are: (A) - (II), (B) - (IV), (C) - (I), (D) - (III).
