α-helices and β-sheets are examples of secondary protein structure, which involves the folding of polypeptide chains into regular, repeating patterns. Primary structure refers to the linear sequence of amino acids, tertiary structure refers to the overall 3D shape of a single polypeptide chain, and quaternary structure involves the arrangement of multiple polypeptide chains in a protein complex.
