Reactivity of ozone towards micelle incorporated unsaturated compounds.
Incorporation of reactive substrates (i.e., lipids) to membranes could protect them towards ozone mediated chain oxidation processes. We have measured the effect of incorporation of unsaturated compounds (stilbene or alkyl methacrylate) in sodium dodecyl sulfate micelles on their reactivity towards ozone. It is found that incorporation of substrate in the micellar pseudophase barely modifies their reactivity towards ozone. The same conclusion is reached when stilbene is incorporated to di-octadecyl-dimethylammonium chloride vesicles. These results would indicate that incorporation of a reactive olefinic compound to a lipidic microphase does not provide "per se" an efficient protection towards its attack by ozone.
