Which type of interaction stabilizes the α helix and the β pleated sheet structures of proteins?

Question

Quizplus · Accepted Answer

Both α helix and β pleated sheet structures of proteins are stabilized by hydrogen bonds between the carbonyl and amino groups of the peptide backbone. Hydrophobic interactions play a role in protein folding and maintaining protein structure, but they do not specifically stabilize these particular secondary structures. Ionic bonds, peptide bonds, and covalent bonds also contribute to overall protein stability but do not specifically stabilize α helices and β sheets.
