Synchrotron small-angle X-ray scattering(SAXS) was used to determine structural changes in the systems of the reverse phospholipid micelles in hexane before and after various incubation periods of oxidation.Experimental scattering curves from PLPE system in hexane indicated that the samples were polydipersed.The scattering particles in this case are bigger

in an oval shape of larger ellipticity

than those in other phospholipid systems studied.The widest distribution reflects the presence of two different fractions in the sample of 3-d oxidation.After possible sedimentation of the biggest particles size distribution function becomes narrower for the sample of 6-d oxidation

3-d oxidation seems to be a critical period of the oxidation process.
