Question

Quizplus · Accepted Answer

Secondary structure in proteins is mainly maintained by hydrogen bonds between the carbonyl group of one amino acid and the amino group of another amino acid in the backbone. Specifically, α-helices are held together by hydrogen bonding between the carbonyl group of one amino acid and the amino group of another amino acid four positions down the chain, while β-sheets are held together by hydrogen bonding between adjacent strands. Covalent bonds between the carbonyl and amino groups of the amino acids form peptide bonds, which make up the backbone of the protein but do not contribute to maintaining secondary structure. Disulfide bonds are important for tertiary and quaternary structure, but not secondary structure. Hydrogen bonds between two amino groups do not contribute significantly to secondary structure.
