Oxidation of ferrous iron during peroxidation of lipid substrates

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1987
Oxidation of Fe2+ in solution was dependent upon medium composition and the presence of lipid. The complete oxidation of Fe2+ in 0.9% saline was markedly accelerated in the presence of phosphate or EDTA and the ferrous oxidation product formed was readily recoverable as Fe2+ by ascorbate reduction.

The role of lipid peroxidation and antioxidants in oxidative modification of LDL

Free Radical Biology and Medicine, 1992
The purpose of this study is to provide a comprehensive survey on the compositional properties of LDL (e.g., lipid classes, fatty acids, antioxidants) relevant for its susceptibility to oxidation, on the mechanism and kinetics of LDL oxidation, and on the chemical and physico-chemical properties of LDL oxidized by exposure to copper ions.

Methods for monitoring oxidative stress, lipid peroxidation and oxidation resistance of lipoproteins

Clinica Chimica Acta, 2001
After a brief discussion of lipid peroxidation mechanism and the action of antioxidants and their potential to exhibit prooxidant effects, we give an overview on the clinical relevance of oxidative stress parameters. Many diseases are associated with oxidative stress e.g.

Urinary Nitric Oxide Metabolites and Lipid Peroxidation By-Products in Migraine

Cephalalgia, 2003
Enhanced endothelium nitric oxide (NO) and superoxide anion release may cause migraine through related cerebral blood flow changes. Thirty subjects suffering from migraine with and without aura and 20 healthy controls were investigated.

Ascorbic Acid Oxidation and Lipid Peroxidation in Milk

Journal of Food Science, 1962
SUMMARY Ascorbic acid oxidation was studied in relation to the natural copper level and to lipid peroxidation in milks produced by cows receiving alfalfa bay or pasture. Correlations were highly significant (r = 0.79**) between ascorbic acid oxidation rate and natural copper for both alfalfa and pasture milks.

The Peroxide Oxidation of Membrane Lipids and Natural Antioxidants

Russian Chemical Reviews, 1985
The ways, in which membrane lipids are oxidised, are considered and the initiating and protective systems influencing the rate of this process are classified. The regulatory role of the interrelation between the composition of the membrane lipids and the degree of their oxidation, which makes it possible to regard this process as a procedure for the ...

Oxidation Kinetics of Fluorescent Membrane Lipid Peroxidation Indicators

ACS Chemical Biology
The oxidation of the cellular membrane through lipid peroxidation (LPO) is linked to aging and disease. Despite the physiological importance, the chemical mechanisms underlying LPO and oxidative reactions in membranes in general remain incompletely understood, and challenges exist in translating LPO inhibitor efficacies from in vitro to in vivo.

Oxidative imbalance and lipid peroxidation in Alzheimer's disease

Drug Development Research, 2002
AbstractAlzheimer's disease (AD) is a growing serious public health problem worldwide. Clinically, AD is a progressive neurodegenerative disorder characterized by a global cognitive decline. There is significant evidence that reactive oxygen species‐mediated reactions, particularly of neuronal lipids, are extensive in those AD brain areas directly ...

Inhibition of oxidative hemolysis and lipid peroxidation by mepacrine.

Journal of biochemistry, 1981
Mepacrine at 50 microM completely protected vitamin E-deficient rat erythrocytes from peroxidative hemolysis induced by dialuric acid or reduced glutathione under the standard experimental conditions. Malondialdehyde formation, which precedes the hemolysis, was also inhibited by mepacrine.

[Indices of oxidative stress. 2. Lipid peroxides].

Ukrains'kyi biokhimichnyi zhurnal (1999 ), 2007
Two methods of the determination of lipid peroxidation products have been compared which are based on Fe(II) oxidation by them at acid pH values in the presence of xylenol orange which binds Fe(III) have been compared. The first method uses cumene hydropeoxide as an internal standard.
