Question

11. Denaturation usually destroys all of the following bonds in protein EXCEPT
A. hydrogen bonds.
B. covalent bonds.
C. hydrophobic bonds.
D. electrostatic bonds.​

Answer 1

Answer:

Denaturation follows the breakdown of the tertiary configuration of the protein concerned, by rupture of the weak ionic bonds responsible for maintaining the linkage between amino acids in the secondary structure.

Answer 2

Denaturation of proteins does not destroy covalent bonds between amino acids.

(option B)

• Denaturation is the process by which tertiary and quaternary proteins are broken down to their simplest linear form.
• Agents of denaturation include heat, radiation and enzymes.
• All kinds of interactions such as hydrogen bonds, hydrophobic bonds and electrostatic bonds involved in the folding of proteins are broken.
• The only bonds that remain are those which make up the primary structure- covalent peptide bonds between amino acid residues.
