The conformation of a protein molecule depends on several different types of bonds and group interactions. which of these usually remains intact when a protein is denatured

Answer;

-When a protein is denatured, the primary structure remains intact, that is the peptide bonds joining amino acids are not broken by denaturing agents.

Explanation;

-The function of a protein is absolutely dependent on its three-dimensional structure. A number of agents can disrupt this structure thus denaturing the protein.

-These agents include; changes in pH, changes in salt concentration, l which alters electrostatic interactions between charged amino acids, changes in temperature (higher temperatures reduce the strength of hydrogen bonds) and finally the presence of reducing agents which break S-S bonds between cysteines.

None of these denaturing agents breaks peptide bonds, so the primary structure of a protein remains intact when it is denatured.
