Protein found in a biological system with a unique three - dimensional structure and biological activity is called a native protein. When a protein in its native form , is subjecteed to a physical change like change in temperature or a chemical change like , change in p H , denaturation of protein takes place. Explain the cause.

1.	Protein found in a biological system with a unique three - dimensional structure and biological activity is called a native protein. When a protein in its native form , is subjecteed to a physical change like change in temperature or a chemical change like , change in p H , denaturation of protein takes place. Explain the cause.
Answer» Solution :Due to a physical or a chemical change , H-bonds in proteins are broken , globules unfold and helices GET uncoiled to form a THREAD LIKE molecuole. As a result , secondary and tertiary STRUCTURES are destroyed and the protein loses its biological activity. This process is called DENATURATION of proteins.
