List - I | List - II | ||
(a) | Protein | (i) | C=C double bonds |
(b) | Unsaturated fatty acid | (ii) | Phosphodiester bonds |
(c) | Nucleic acid | (iii) | Glycosidic bonds |
(d) | Polysaccharide | (iv) | Peptide bonds |
The correct matchings are:
(a) Protein - Proteins are made up of amino acids, and the bonds that link these amino acids together are called peptide bonds. So, (a) matches with (iv).
(b) Unsaturated fatty acid - Unsaturated fatty acids typically have C=C double bonds. So, (b) matches with (i).
(c) Nucleic acid - Nucleic acids, like DNA and RNA, are composed of nucleotides, and the bonds that connect these nucleotides are called phosphodiester bonds. So, (c) matches with (ii).
(d) Polysaccharide - Polysaccharides are large carbohydrate molecules made up of many sugar units (monosaccharides), and the bonds that link these sugar units together are glycosidic bonds. So, (d) matches with (iii).
So, the correct option is (B): (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii)
Biomolecules are the most essential organic molecules, which are involved in the maintenance and metabolic processes of living organisms. These non-living molecules are the actual foot-soldiers of the battle of sustenance of life.
There are four major classes of Biomolecules – Carbohydrates, Proteins, Nucleic acids and Lipids.
