NEET Chemistry Proteins Match the Following Question

Type: Match the Following-match the column-Hard-Class 12

Match Column-I with Column-II.

Column-IColumn-II
(a) Primary structure(i) Insulin
(b) Globular proteins(ii) Zwitter ion
(c) Amphoteric behaviour(iii) Sequence of amino acids
(d) Optically active amino acids(iv) Glycine
A

a-iii, b-i, c-ii, d-iv

B

a-ii, b-i, c-iv, d-iii

C

a-iv, b-ii, c-i, d-iii

D

a-ii, b-iii, c-i, d-iv

Correct Answer

Option A

Detailed Explanation

The primary structure of proteins refers to the specific sequence of amino acids (a-iii). Globular proteins, such as insulin, have a spherical shape and are soluble in water (b-i). Amino acids exhibit amphoteric behavior, acting as both acids and bases in their zwitter ionic form (c-ii). Except for glycine, all naturally occurring amino acids are optically active (d-iv).
