Question

Quizplus · Accepted Answer

The primary structure of a protein, which is its sequence of amino acids, is held together by peptide bonds rather than hydrogen bonds. Disruptions in hydrogen bonding mainly affect the secondary, tertiary, and quaternary structures, which involve the folding and interaction of the protein's backbone and side chains.
