Which type of biochemical bond is responsible for the stability of the alpha-helix structure in proteins?
Explanation
Hydrogen bonds between the carbonyl oxygen and the amide hydrogen of adjacent turns of the helix stabilize the alpha-helix structure, whereas disulfide bonds are covalent links between cysteine residues, peptide bonds are the links between amino acids, and glycosidic bonds are found in carbohydrates.
