You won’t be wrong if you say that life on Earth won’t be possible without polymers. Wonder why? Look at what our body is made of. Our body contains proteins, peptides and enzymes. These wouldn’t be possible if not for RNA, which is a polymer. RNA makes possible the synthesis of proteins and enzymes. Our hair is made of keratin, a protein and skin is constituted of polymerized collagen. DNA contains the basic programming of our body. DNA too is a polymer.
Polymers make up not only the human body, but also plants and animals. A rhino’s horn is made of keratin while cell walls of plants are made of cellulose. The list does not end here. Several other polymers like chitin are found in organisms like crabs. Let us now take a close look at different natured polymers.
