Domain catalyzed chemical reactions: a molecular dynamics simulation of isomerization kinetics.
The model for domain catalyzed isomerization kinetics in condensed fluids is applied for a diluted mixture of a chiral solute with a consolute temperature. The solution is quench to phase separation at temperatures below the consolute temperature. The droplet coalescence enhances the isomerization kinetics due to the substantial excess pressure inside the small droplets given by the Laplace equation. The domain catalyzed isomerization kinetics breaks the symmetry, and the droplets end with only one dominating species. We argue that D-glyceraldehyde which is only moderately solvable in water and which has played a crucial role in the evolution is a candidate for the stereo specific ordering in bio-organic matter.
