Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The loss of a protein’s structure is called ____
A
Denaturation
B
Unfolding
C
Coiling
D
Inactivation
Explanation: 

Detailed explanation-1: -The uncoiling of helix structure affects the chemistry of proteins and they lose their biological activity. This phenomenon of losing their activity and uncoiling of helix structure due to physical or chemical changes is called the denaturation of proteins.

Detailed explanation-2: -denaturation, in biology, process modifying the molecular structure of a protein. Denaturation involves the breaking of many of the weak linkages, or bonds (e.g., hydrogen bonds), within a protein molecule that are responsible for the highly ordered structure of the protein in its natural (native) state.

Detailed explanation-3: -Denaturation is a process in which proteins lose their shape and, therefore, their function because of changes in pH or temperature.
