Factors determining the direction of the stereoselection process in the generalized Frank model

The Frank model for spontaneous chiral stereoselection of biomolecules is extended by taking into account the influence of electroweak effects on the rates of enantiomeric chemical reactions. Explicit analytical solutions of the respective differential 'equations are obtained, describing the behaviour of the generalized Frank model immediately after the beginning of the process, when the direction of the stereoselection is decided. The direction of the stereoselection is affected by both stochastic and deterministic factors, whose complex interrelations are examined.received by the Publisher 20 September 1989
