The kinetics of the growth of an accidentally created chiral biomolecule in the racemic prebiotic medium

摘要

A mathematical model is presented to show that a chiral (e.g. l) isomer of a self-replicating biomolecule, created accidentally in the prebiotic medium, could grow rapidly, consuming nearly all l and d forms of nutrients in the medium. A high chiral selectivity is reached in a time comparable to the racemization time of the nutrient species, whose l and d enantiomers were present in equal concentrations at the beginning.
