Hierarchy of structural order in roteins Primary structure the complete sequence of amino acids(aa)in the polypeptide chain. scale: 1 nm Secondary structure: the local chain configuration sequence of 3-5 AA) Scale 10 nm Tertiary structure: the configuration of the entire macromolecule, scale: 100 nmHierarchy of structural order in proteins Primary structure: the complete sequence of amino acids (AA) in the polypeptide chain. Scale: 1 nm. Secondary structure: the local chain configuration (sequence of 3 - 5 AA). Scale: 10 nm. Tertiary structure: the configuration of the entire macromolecule. Scale: 100 nm. 9
