What maintains the secondary structure of a protein?
A) peptide bonds
B) hydrogen bonds between the amino group of one peptide bond and the carboxyl group of another peptide bond
C) disulfide bonds
D) hydrophobic interactions
E) hydrogen bonds between the R groups

Question

Quizplus · Accepted Answer

The secondary structure of a protein is maintained by hydrogen bonds between the amino group of one peptide bond and the carboxyl group of another peptide bond, forming alpha helices and beta sheets. Peptide bonds and disulfide bonds contribute to the primary and tertiary structure of a protein, respectively, and hydrophobic interactions and hydrogen bonds between R groups contribute to the tertiary and quaternary structure of a protein, respectively.
