The following is an excerpt from a recent scientific publication:“The secondary structure contains regions of amino acid chains that are stabilized by hydrogen bonds from the polypeptide backbone. These hydrogen bonds create alpha-helix and beta-pleated sheets… interactions of side chains… determine tertiary structure. The quaternary structure also influences the protein’s 3‑dimensional shape and is formed through side‑chain interactions between two or more polypeptides.” Which statement is correct regarding structural hierarchy?
