Which type of interaction stabilizes the α helix and the β pleated sheet structures of proteins?
A) hydrophobic interactions
B) disulfide bonds
C) ionic bonds
D) hydrogen bonds
E) peptide bonds

Question

Quizplus · Accepted Answer

Both α helix and β pleated sheet structures of proteins are stabilized by hydrogen bonds between the backbone atoms of the polypeptide chain. Hydrophobic interactions, disulfide bonds, ionic bonds, and peptide bonds are important for other aspects of protein structure and stabilization, but not specifically for the α helix and β pleated sheet structures.
