非线性自催化和再循环诱导的完全同手性

Complete homochirality induced by the nonlinear autocatalysis and recycling

Yukio Saito, Hiroyuki Hyuga

摘要:

在一个封闭体系中,手性物质的非线性自催化作用可以实现同手性,如果包括逆反应的话。由于非线性自催化作用,两种对映体浓度的不对称性或对映体过量增加。此外,当考虑到逆反应时,由对映异构体的分解提供的反应物被再循环以产生越来越多的占主导地位的反应物,并最终建立同手性。

英文摘要:

A nonlinear autocatalysis of a 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 the 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 and more the dominant one, and eventually the homochirality is established.
