Detailed explanation-1: -When a protein is denatured, secondary and tertiary structures are altered but the peptide bonds of the primary structure between the amino acids are left intact. Since all structural levels of the protein determine its function, the protein can no longer perform its function once it has been denatured.

Detailed explanation-2: -During the denaturation of proteins, the secondary and tertiary structures get destroyed and only the primary structure is retained. Covalent bonds are broken and interaction between amino-acid chains gets disrupted. This results in the loss of biological activity of the proteins.

Detailed explanation-3: -Denaturation of proteins involves the disruption and possible destruction of both the secondary and tertiary structures. Since denaturation reactions are not strong enough to break the peptide bonds, the primary structure (sequence of amino acids) remains the same after a denaturation process.

Detailed explanation-4: -A. Denaturation breaks the covalent bonds that hold the protein in its three-dimensional shape. Without the proper shape, the protein cannot function. B. Denaturation destroys the primary structure of the protein, and the protein breaks down to monomers.

Detailed explanation-5: -Because many of the proteins original bonds have been broken, those parts of the molecule are now available to make new bonds with other substances. This changes the way the molecule reacts. Since a protein’s function is dependent on its shape, a denatured protein is no longer functional.
