Reactive molecular dynamics simulations are performed to study the interaction of reactive oxygen species, such as OH, HO2 and H2O2, with the endotoxic biomolecule lipid A of the gramnegative bacterium Escherichia coli . It is found that the aforementioned plasma species can destroy the lipid A, which consequently results in reducing its toxic activity. A clear difference is observed in the bond breaking mechanisms upon impact of HO2 radicals and H2O2 molecules on one hand and OH radicals on the other hand. Our simulation results are in good agreement with experimental observations.
