Interpretation Introduction

Interpretation:

The protein $\text{α}$ -keratin and its functions and modifications are to be described.

Concept Introduction:

The long chains of amino acids which are linked to each other through peptide bonds are known as proteins. They act as the building blocks of the body. Proteins make up the structures such as muscles, skin and hair.

In the body, many chemical reactions are controlled by proteins which play a major role in metabolic processes. They also play a crucial role in the transportation of certain molecules such as oxygen, which is transported from lungs to cells. They form antibodies to fight against infections and diseases.
