NEET Chemistry Proteins Match the Following Question
Match Column-I with Column-II.
Column-I Column-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
Choose the correct matching:
a-iii, b-i, c-ii, d-iv
a-ii, b-i, c-iv, d-iii
a-iv, b-ii, c-i, d-iii
a-ii, b-iii, c-i, d-iv
Correct Answer
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).
