The secondary structure of protein, such as the alpha-helix, is stabilized primarily by:
Show answer and explanation
Correct answer: Hydrogen bonds
Hydrogen bonds between the carbonyl oxygen and the amide hydrogen of the polypeptide backbone stabilize secondary structures like the alpha-helix and beta-pleated sheets. Disulfide bonds contribute to tertiary structure.
