title: [Structural presentation of oxygen: its medical value].
abstract: Oxygen is presented as a molecule transported by the heme. The use of molecular energy diagrams makes possible to visaulize the energy levels related with the atomic and molecular orbitals in the case of considering the oxygen atom with and without hybridation. Get up of Griffith's and Pauling's models relative to the nature of the O2-Fe-Heme bindings.
