The asymmetry of biological molecules and the symmetry CPT.
Due to the interference of weak nuclear and electromagnetic forces, a specific relationship exists between the electric polarization of the covalent bonds and the spatial orientation of certain atoms and chemical groups in the framework of matter. The symmetric in the mirror corresponding to this relationship is in antimatter (symmetry CP). In this transformation, time preserves its direction of development (symmetry CPT).
