WebLevels of Protein Structure. Proteins are polypeptides of amino acid chains that fold into various structures in order to carry out their biologic function. There are four specific levels of protein structure: primary, secondary, tertiary, and quaternary ( Figure 1 ). Below is an outline of each structure, including the interactions that hold ... WebFigure 7.23 summarizes the four levels of protein structure. Figure 7.19 The primary structure of a protein is the sequence of amino acids. (credit: modification of work by National Human Genome Research Institute) Figure 7.20 The secondary structure of a protein may be an α-helix or a β-pleated sheet, or both.
