Question

State True or False.
Proteins are natural polymers.
(A) True
(B) False

Answer 1

Hint: Polymers are macromolecules built up by linking together a large number of small molecules. The repeating units in a polymer are linked through with strong covalent bonds. Small molecules which combine with each other to form polymer molecules are called monomers. The process of preparation of polymers in the laboratory is called the polymerization process.

Complete answer:
In Greek, poly means many and met means unit.
The polymers are classified into many types based on their physical and chemical properties.
The classification of polymers as,
-based on source
-Based on monomers
-Based on polymerization
-Based on functionality
-Based on intermolecular forces
-Based on structure
-Based on source:
Polymers are classified into two types based on availability of source or abundance in nature.
Those are natural polymers and synthetic polymers.

-Natural polymers: These polymers are available in nature such as plants and animals. Examples are proteins, cellulose, starch, some resins, and natural rubber.
-Synthetic polymers: these variety of synthetic polymers as plastic, synthetic fibers, and synthetic rubbers are examples for man-made polymers prepared in daily life as well as in industry or in laboratories
From the definition of natural polymers, Proteins are natural polymers.
Proteins are polymers of amino acids. Each amino acid contains a peptide bond $-CO-N{{H}_{2}}-$ variable with the R group.

So the given statement is True. (Option A).

Note:
natural polymers that are readily abundant from nature like natural rubber. Natural rubber is a polymer obtained from latex, a milky liquid present in cells of rubber-producing plants. The chemical name of natural rubber is polyisoprene.
