Asymmetric autocatalysis and its implications for the origin of homochirality

Donna G. Blackmond

Abstract: An autocatalytic reaction in which the reaction product serves as a catalyst to produce more of itself and to suppress production of its enantiomer serves as a mechanistic model for the evolution of homochirality. The Soai reaction provided experimental confirmation of this concept, nearly 50 years after it was first proposed. This Perspective offers a rationalization of the Soai autocatalytic reaction; accounting for enantiomeric excess and rate observations, that is both simple as well as gratifying in its implications for the chemical origin of life.

The ISCID Forums are aimed at generating insight into the nature of complex systems (e.g. biological complexity, organizational complexity, etc.) and the ontological status of purpose, especially from the vantage point of various information- and design-theoretic models.
