What is the essence of the denaturation?
A
Desintegration of low-energy bonds
B
Desintegration of peptide bonds
C
Desintegration of amino acids
D
Desintegration of proteins
Explanation: 

Detailed explanation-1: -Denaturation is the process of the modification of the molecular structure of a protein. This involves the breakdown of bonds such as hydrogen bonds and covalent bonds (disulfide bonds (S-S). Proteins generally have a compact globular shape or are “folded” instead of having random structures.

Detailed explanation-2: -Protein Denaturation: Unraveling the Fold When a protein denatures, its complicated folded structure unravels, and it becomes just a long strand of amino acids again. Weak chemical forces that hold tertiary and secondary protein structures together are broken when a protein is exposed to unnatural conditions.

Detailed explanation-3: -Denaturation breaks the covalent bonds that hold the protein in its three-dimensional shape. Without the proper shape, the protein cannot function. Denaturation destroys the primary structure of the protein, and the protein breaks down to monomers.

Detailed explanation-4: -At the level of the biological system, denaturation is used by the body to kill pathogens. It does so through pH regulation and biochemical secretions. Denaturation is also important during food digestion. Proteins in food are denatured by the action of the released digestive enzymes.
