Primary StructureAs discussed in the Protein 1 module, proteins have a specific sequence of amino acids, starting from their N-terminus and proceeding to their C-terminus. This sequence is called the protein's primary structure . As the structures of hemoglobin (left) and ribonuclease (right) below show, however, there is a lot more to a protein's structure than just its primary structure. Scientists divide this structure into four broad hierarchical levels: primary, secondary, tertiary, and quaternary. |
