Tertiary protein structure is maintained by________. (Select all that apply)

Question

Quizplus · Accepted Answer

Tertiary protein structure is maintained by various types of bonds and interactions, including hydrogen bonds, ionic bonds, and disulfide bridges. Hydrogen bonds occur between polar side chains and the peptide backbone or between polar side chains themselves. Ionic bonds form between positively and negatively charged side chains. Disulfide bridges are covalent bonds that form between the sulfur atoms of cysteine residues, providing significant stability to the protein structure. Hydrophilic interactions are not a specific type of bond but rather refer to the overall effect of polar side chains interacting with the aqueous environment, which influences the folding and stability of the protein rather than directly maintaining its structure.
