List-I Amino acid |
List-II Example |
|
(A) Basic amino acid |
(IV) Lysine |
|
(B) Acidic amino acid |
(III) Proline |
|
(C) Neutral amino acid |
(II) Alanine |
|
(D) Optically inactive amino acid |
(I) Glycine |
Basic amino acid (A): Lysine (IV) — side chain has an extra -NH₂ group (positively charged at physiological pH).
Acidic amino acid (B): Proline (III) — Note: Proline is actually neutral (non-polar), not acidic. No true acidic amino acid (e.g., aspartic/glutamic acid) is in List-II, so this is assigned by elimination (likely a question flaw or intent to test recognition).
Neutral amino acid (C): Alanine (II) — simple non-polar/neutral side chain (-CH₃).
Optically inactive amino acid (D): Glycine (I) — achiral (side chain is H, no chiral center).
