title: On the origin of "pure" chirality of amino acids and saccharides at the prebiotical stage.
abstract: Possible explanation is offered for the origin of pure chirality of amino acids and saccharides of racemic compounds during the prebiotical stage of evolution. It is based on the theory of "noise induced phase transitions", a mechanism approached in previous years by synergetic methods. It follows from this approach that a sufficiently intensive noise in the environment of the formation of racemic compounds of L- and D-chiralic macromolecules could produce homochiralic state, i.e. a state with either pure L- or D-chirality.
