The secondary structure of protein includes
Correct answer: A. α-helix and β-pleated sheet
- A. α-helix and β-pleated sheet
- B. Quaternary folding
- C. Amino acid sequence
- D. Disulfide bridges
Explanation
Secondary structure involves local folding into α-helix or β-pleated sheet, stabilized by hydrogen bonds between backbone atoms.

About Proteins
Proteins are polymers of amino acids joined by peptide bonds, and their function depends on primary, secondary, tertiary and quaternary structure. The topic covers fibrous and globular proteins, enzymes, antibodies, hormones and transport proteins, as well as denaturation by heat or extreme pH.
