Book ChapterDOI
Microsomal lipid peroxidation.
John A. Buege,Steven D. Aust +1 more
TL;DR: This chapter discusses microsomal lipid peroxidation, a complex process known to occur in both plants and animals that involves the formation and propagation of lipid radicals, the uptake of oxygen, a rearrangement of the double bonds in unsaturated lipids, and the eventual destruction of membrane lipids.
Journal ArticleDOI
Role of metals in oxygen radical reactions
TL;DR: Factors such as pH and chelation govern the reactivity of the transition metals with dioxygen and "oxy-radicals" and therefore influence the apparent mechanisms by which oxidative damage to phospholipids, DNA, and other biomolecules is initiated.
Journal ArticleDOI
Oxidation of persistent environmental pollutants by a white rot fungus.
TL;DR: Model studies suggest that the ability of Phanerochaete chrysosporium to metabolize these compounds is dependent on the extracellular lignin-degrading enzyme system of this fungus.
Journal ArticleDOI
Transition metals as catalysts of "autoxidation" reactions.
TL;DR: The quantum mechanic, thermodynamic, and kinetic aspects of the reactions of dioxygen with biomolecules; the involvement of transition metals in biomolecule oxidation; and the biological implications of metal catalyzed oxidations are discussed.
Journal ArticleDOI
The requirement for iron (III) in the initiation of lipid peroxidation by iron (II) and hydrogen peroxide.
Giorgio Minotti,Steven D. Aust +1 more
TL;DR: Using Fe2+, H2O2, and phospholipid liposomes as a model system, it is found that lipid peroxidation, as assessed by malondialdehyde formation, is not initiated by the hydroxyl radical, but rather requires Fe3+ and Fe2+.
