Peroxidation of linoleic acid induced by interaction with haemoglobin and hydrogen peroxide.
Peroxidation of linoleic acid was found to be induced by interaction with haemoglobin and hydrogen peroxide, and was accelerated by ascorbic acid.

Hydrogen and perpetuate the chain reaction of lipid peroxidation (Gutteridge) by the equations below, in which lipid* symbolises a carbon-centred radical.
The role of erythrocyte peroxiredoxin in detoxifying peroxides and in stimulating potassium efflux via the Gardos channels.
Using mice deficient in glutathione peroxidase, Johnson et al reported that this enzyme plays an important role within erythrocytes in the detoxification of organic peroxides.[1][1] The authors
Lipid peroxidation and antioxidants as biomarkers of tissue damage.
The body has a hierarchy of defense strategies to deal with oxidative stress within different cellular compartments, and superimposed on these are gene-regulated defenses involving the heat-shock and oxidant stress proteins.
Haemoglobin and myoglobin as inhibitors of hydroxyl radical generation in a model system of "iron redox" cycle.
The pro-oxidative or anti-Oxidative activities of haemproteins in biological oxidative reactions seem to be dependent on compartmentalization and on the presence and concentrations of reducing compounds and H2O2.
Decompartmentalised Iron, Microbleeding and Membrane Oxidation
In pathological states, current models which account for the phenomenon of oxidative stress in cells and tissues include: increased generation of oxygen radicals, modified antioxidant defences and

Iron redox reactions and lipid peroxidation.


The role of iron in ferritin- and haemosiderin-mediated lipid peroxidation in liposomes.
Results indicate that, at pH 4.5, even in the absence of a reducing agent, iron is released from haemosiderin and can mediate oxidative damage to a lipid membrane.
Low-molecular-weight iron complexes and oxygen radical reactions in idiopathic haemochromatosis.
It is suggested that oxygen radical reactions stimulated by iron salts are important in the pathology of idiopathic haemochromatosis.
Ferritin and superoxide-dependent lipid peroxidation.
Data suggest that ferritin may function in vivo as a source of iron for promotion of superoxide-dependent lipid peroxidation, and that initiation is not via an iron-catalyzed Haber-Weiss reaction.
Role of metals in oxygen radical reactions.
Superoxide-dependent formation of hydroxyl radicals in the presence of iron salts. Detection of 'free' iron in biological systems by using bleomycin-dependent degradation of DNA.
Human synovial fluid, human cerebrospinal fluid and rat pleural-exudate fluid were found to contain micromolar concentrations of 'free' iron, which would be sufficient to allow formation of the hydroxyl radical from superoxide and hydrogen peroxide generated in vivo.
