helical structure is kept by the formation of _________ bonds among amino acids molecules?

Explanation

An alpha helix is stabilized by hydrogen bonds between the carbonyl oxygen of one peptide bond and the hydrogen of another peptide bond in the same polypeptide chain. Disulphide bonds and ionic interactions can stabilize higher levels of protein structure, but they do not produce the regular alpha-helical backbone pattern. Students may choose b because disulphide bonds are important in protein folding, confusing tertiary stabilization with secondary structure.
