A)peptide bonds
B)hydrogen bonds

D)ionic bonds
E)phosphodiester bonds

Question

Quizplus · Accepted Answer

The secondary structure of a protein is maintained primarily by hydrogen bonds between the backbone atoms of the protein. These bonds are between the oxygen of the carbonyl group of one amino acid and the hydrogen of the amino group of another amino acid, forming alpha helices or beta sheets. Other types of bonds, such as disulfide bonds, ionic bonds, and phosphodiester bonds, contribute to tertiary and quaternary structures but not the secondary structure.
