The structure of a protein refers to the linear sequence of amino acids in that protein. Make up an example of the primary structure of a protein in the space below. The structure of a protein refers to a regular, recurring arrangement of the amino acid chain. One such arrangement called the occurs when the amino acid chain forms a spiral or coil. Draw an example of this structure in the space below.
