The tertiary structure of proteins depends primarily on which property of amino acids?
I. disulfide bonds
II. hydrogen bonds
III. amide bonds
IV. polar side chains

Question

Quizplus · Accepted Answer

The tertiary structure of proteins is primarily determined by disulfide bonds (I) and hydrogen bonds (II). Disulfide bonds form between the sulfur atoms of cysteine residues, stabilizing the 3D structure. Hydrogen bonds occur between the backbone and side chains, further contributing to the protein's overall shape. Amide bonds (III) are involved in the primary structure, linking amino acids together in a chain, while polar side chains (IV) are more relevant to the protein's solubility and secondary interactions.
