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) Sequence of amino acids (c) Zwitter ion (iii) Amphoteric behavior (d) Optical activity (iv) Asymmetric a-carbon
Choose the correct matching:
a-ii, b-i, c-iii, d-iv
a-ii, b-iv, c-i, d-iii
a-iv, b-ii, c-iii, d-i
a-iii, b-i, c-iv, d-ii
Correct Answer
Detailed Explanation
The primary structure of proteins refers to the specific sequence of amino acids (a-ii). Globular proteins like insulin have a spherical shape (b-i). Zwitter ions exhibit amphoteric behavior due to their positive and negative charges (c-iii). Optical activity is associated with amino acids that have an asymmetric a-carbon, which is true for most except glycine (d-iv).
