Question

read this! heating and changing ph levels are two ways to disrupt the shape of a protein. high temperatures or ph levels that vary from the natural environment of the protein will break hydrogen bonds, ionic bonds, disulfide bridges, and hydrophobic interactions. covalent bonds will usually remain undisturbed. this process of destroying the shape of a protein is called denaturing. 24. which of the four levels of protein structure is maintained after denaturing? explain your answer.

Explanation:

Denaturing breaks hydrogen, ionic, disulfide, and hydrophobic interactions but covalent bonds remain. The primary structure of a protein is held together by covalent peptide bonds. Since covalent bonds are usually undisturbed during denaturing, the primary structure is maintained.

Answer:

The primary structure of the protein is maintained after denaturing because denaturing mainly disrupts non - covalent bonds (hydrogen, ionic, disulfide bridges, hydrophobic interactions) and covalent bonds (which hold the primary structure together) are usually not affected.
