E)hydrogen bonding.

Question

Quizplus · Accepted Answer

Helical and sheet-like segments in proteins arise from hydrogen bonding. Helices are stabilized by hydrogen bonds between the amide groups of the backbone, while beta sheets are stabilized by hydrogen bonds between adjacent strands. Disulfide bridges, salt bridges, covalent bonds, and dispersion forces may contribute to overall protein structure, but they do not specifically give rise to helices and sheets.
