TL;DR: The feasibility of penetration of superoxide radicals through liposomal membrane, predominantly via anionic channels, was demonstrated by the use of an intramolecular cholesterol-amphotericin B complex.

TL;DR: In this paper, the relay transfer of unoxygenated free radical to the side hydrocarbon chain of an antioxidant molecule is described, and in subsequent steps the aroxyl radical is formed by the intramolecular rearrangement of radical in an antioxidant molecules.

TL;DR: Green alga reinhardtii cells, grown at atmospheric CO2 for 3 h in the dark under anaerobic conditions, not only induced hydrogenase activity but also increased the Fe(II) content in the cells up to the saturation level observed in cells grown aerobically at high CO2, which suggests a correlation between the amount of Fe( II) cations stored in the Cells, the CO2 concentration, and anaerobiosis.

TL;DR: It is shown that for lipid monolayers, the O(2) permeability coefficients are three to four orders of magnitude lower than has been previously thought, indicating that lipid membranes constitute a considerable barrier to O( 2) diffusion.

TL;DR: The results indicate that Cl− anions are not directly involved in water oxidation by the Mn cluster in the native PSII membranes, but possibly provide access for H2O molecules to the Mn4CaO5 cluster and/or facilitate the release of H+ ions into the lumenal space.
