WebDenaturation of the proteins is a condition when the unique three-dimensional structure of a protein is exposed to changes. Due to changes in temperature, pH or other chemical activities, the hydrogen bonds present in the proteins get disturbed. This results in the unfolding of globular proteins and uncoiling of the helix structure.
