详细

Steady state radiolysis showed a decrease in the reactivity of quercetin in free radical reactions with the 1-hydroxyethyl radical and the superoxide radical anion as a result of the formation of a complex with a copper ion. The negative effect of copper ions can be reduced via destroying the resulting complex by introducing chelating compounds, such as tartaric acid and EDTA. The nature of the change in reactivity corresponded to the change in the radioprotective activity of quercetin in relation to yeast cells.
