Question

What are the monomers and polymers of protein?

Answer 1

Hint: Proteins are large, complex biomolecules that play many important roles in the body of living beings. Proteins are directly involved in many chemical processes essential for life. Proteins undergo a variety of functions in cells. It was found that proteins have different shapes and molecular weights.

Complete answer:
Before coming to our question let’s see what are monomers;
Monomers are the building blocks of polymers. They are small molecules that can be joined together in a repeating fashion to form more complex molecules known as polymers. For example;
Vinyl chloride polymerises to form polyvinyl chloride commonly known as PVC.
Now, coming to our question;
The monomers of proteins are amino acids. These monomers are linked together to form polypeptide chains. We can say that amino acids are the building blocks of proteins.
Each amino acid consist of an acidic carboxyl group $\left( { - COOH} \right)$, a basic amino group $\left( { - N{H_2}} \right)$ and an organic R group which is unique to each amino acid. These amino acids differ from each other in the R group. There are nine essential amino acids that our body can’t produce.
The chemical properties of the amino acids of proteins determines the biological activity of the protein.
Protein is the polymer of monomers (amino acids). The shape, size and function of proteins are determined by the number and the sequence of the monomers (amino acids).

Note:
We have seen that Protein itself is the polymer of amino acids (monomer). Antibodies in the body are protein only that helps the immune system to fight disease. Proteins like collagen, Keratin make up our skin, hair and nails.
