Quizplus · Accepted Answer

The coiling of the protein chain into an alpha helix represents the secondary structure of a protein. The primary structure represents the linear sequence of amino acids and the tertiary structure refers to the overall 3D folding of a protein, while the quaternary structure relates to the arrangement of multiple protein subunits.
