What is the effect of denaturation on the structure of proteins?

Explanation

As a result of denaturation, secondary and tertiary structures of proteins are destroyed but primary structure remains unchanged. During denaturation, H-bonds are broken, globules unfold and helics get uncoiled to form thread-like molecules. In other words, globular proteins (which are soluble in water) undergo coagulation to give fibrous proteins (which are insoluble in water).
