Stability of secondary structures within a protein is a result of
A) disulfide bonds between Cys residues.
B) electrostatic bonds between Glu and Lys side chains.
C) hydrogen bonds between backbone atoms.
D) post_translational modifications to selected amino acids.
E) stacking of aromatic side chains.

Question

Quizplus · Accepted Answer

Secondary structures within a protein, such as alpha helices and beta sheets, are stabilized by hydrogen bonds between backbone atoms. Disulfide bonds, electrostatic bonds, post-translational modifications, and stacking of aromatic side chains do not specifically stabilize secondary structures.
