The structure of the α-helix is determined by a helical substructure of the 4D tube polytope with the symmetry group ±[O×D20]; this substructure has a screw axis 40/11 with the angle of rotation of 99°. This polytope belongs to the family of tube polytopes with the starting groups ±1/2[O×C2n], which determine the screw axes of the α-helices included in superhelices.
