Select one: a. disulfide bonds b. polar side chains c. amide bonds d. hydrogen bonds
Explanation / Answer
Correct option: d. hydrogen bonds
There are two main types of secondary structure known as the -helix and the ß-sheet. Hydrogen bonds form between the oxygen of the C=O of each peptide bond in the strand and the hydrogen of the N-H group of the peptide bond four amino acids below it in the -helix. Whereas in ß-sheet, carbonyl oxygens in one strand hydrogen bond with the amino hydrogens of the adjacent strand. In both cases hydrogen bonds make this structure especially stable.
