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 non - covalent bonds like hydrogen bonds, ionic bonds, disulfide bridges, and hydrophobic interactions but usually leaves covalent bonds intact. The primary structure of a protein is held together by covalent peptide bonds. Since denaturing doesn't typically break covalent bonds, the primary structure remains maintained.

Answer:

The primary structure of the protein is maintained after denaturing because it is held together by covalent peptide bonds which are usually not disrupted during the denaturing process while secondary, tertiary, and quaternary structures that rely on non - covalent interactions are disrupted.
