Quizplus · Accepted Answer

The primary structure of a protein is determined by its amino acid sequence, which 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, not the primary sequence itself.
