Complete homochirality induced by nonlinear autocatalysis and recycling

The nonlinear autocatalysis of the chiral substance is shown to achieve homochirality in a closed system, if the back reaction is included. Asymmetry in the concentration of two enantiomers or enantiometric excess increases due to the nonlinear autocatalysis. Furthermore, when the back reaction is taken into account, the reactant supplied by the decomposition of the enantiomers is recycled to produce more of the dominant enantiomer, and eventually homochirality is established.
