Abstract
New structures of biomolecules have been constructed: carbohydrates, proteins, nucleic acids. It is shown that glucose molecules and ribose molecules have dimensions of 15 and 12, respectively. The enantiomorphic forms of biomolecules in space of higher dimension make it possible to explain the experimentally observed facts of branching of chains of biomolecules in one of the enantiomorphic forms and the absence of chain branching in another enantiomorphic form. The enantiomorphic forms of the tartaric acid molecule in a space of higher dimension reveal the cause of the reversal in different directions of the polarization plane of light in two opposite forms.
