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

Question

Quizplus · Accepted Answer

The α helix and β pleated sheet structures are stabilized by hydrogen bonds. In an α helix, hydrogen bonds form between the carbonyl group of one amino acid residue and the amine group of an amino acid residue four residues away. In a β pleated sheet, hydrogen bonds form between adjacent β strands. These hydrogen bonds stabilize the secondary structure of proteins. Hydrophobic interactions and peptide bonds are important for stabilizing the tertiary structure of proteins, while ionic bonds are not particularly important for stabilizing protein structure.
