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)disulphide bonds
D)hydrophobic interactions
E)hydrogen bonds between the R groups

Question

Quizplus · Accepted Answer

The secondary structure of a protein is mainly maintained by hydrogen bonds between the amino group of one peptide bond and the carboxyl group of another peptide bond, forming either alpha helix or beta sheet structures. Peptide bonds (A) are responsible for forming the backbone of the protein, while disulphide bonds (C) are involved in stabilizing the tertiary and quaternary structures of proteins. Hydrophobic interactions (D) and hydrogen bonds between the R groups (E) are more important for the tertiary and quaternary structures of proteins.
