Lipid peroxidation in homocysteinaemia

Journal of Inherited Metabolic Disease, 1992
Homocysteinaemia due to cystathione synthase deficiency (CSD: McKusick 236200) is a rare autosomal recessive inborn error of methionine metabolism. The most life-threatening complications caused by CSD are thromboembolism and vascular abnormalities.

Thiol-dependent lipid peroxidation

Biochemical and Biophysical Research Communications, 1982
Abstract Initiation of lipid peroxidation in liposomes by cysteine, glutathione, or dithiothreitol required iron, and was not inhibited by superoxide dismutase. The absence of superoxide involvement in thiol autoxidation was confirmed by the inability of superoxide dismutase to inhibit thiol reduction of cytochrome c.

Lipid peroxidation in spermatozoa

Proceedings of the Royal Society of London. Series B. Biological Sciences, 1973
Ram spermatozoa produce aerobically an organic peroxide which can be determined quantitatively by the thiobarbituric acid reaction. The reaction is more intense in sperma­tozoa that have been stored at 5°C. Cold shock and homogenization release from spermatozoa a substance, presumably a lipid, which provides the substrate for peroxidation.

Mechanisms of lipid peroxidation

Journal of Free Radicals in Biology & Medicine, 1985
This article provides an overview of how peroxidation of unsaturated lipids takes place and how it can be measured. Several different aspects of free-radical-mediated lipid peroxidation are discussed, including: the catalytic role of chelated iron and other redox metal ions; induction by reducing agents such as superoxide, ascorbate, and xenobiotic ...

Transferrin-dependent lipid peroxidation

Advances in Free Radical Biology & Medicine, 1986
The potential for iron bound to transferrin to be released and promote the peroxidation of phospholipid liposomes was investigated using ADP as a low molecular weight chelator and superoxide generated by the xanthine/xanthine oxidase system as the reducing agent.

Paraquat and Lipid Peroxidation

Archives of Internal Medicine, 1982
To the Editor. —In the AugustArchives(1981;141:1169-1171), Yasaka et al reported an increase in lipid peroxidation (as measured by serum malondialdehyde levels) after ingestion of paraquat, a bipyridinium compound widely used as a herbicide. The authors suggested that the serum malondialdehyde may have originated from passage of the blood through the ...

Inhibition of lipid peroxidation

Biological Trace Element Research, 1997
Lipid peroxy radicals (ROO.) were detected by electron spin resonance (ESR) at low temperature after formation by addition of H2O2 into a suspension of mice lymphocytes. If lymphocytes were treated with selenomethionine (Se-Met) prior to addition of H2O2, ROO. formation was inhibited in a fashion that was dependent on Se-Met concentration. Formation of

Lipid peroxidation in mitochondria

Free Radical Biology and Medicine, 1988
The present review article takes into consideration the most important aspects of lipid peroxidation in mitochondria. Firstly the various ways by which lipid peroxidation is induced and the relevant mechanisms are described and discussed. After examining the major effects of lipid peroxidation on mitochondrial enzymes and bioenergetic functions, some ...

Lipid peroxidation. Biopathological significance

Molecular Aspects of Medicine, 1993
Peroxidation of unsaturated lipids, initially studied in the chemistry of oil and fat rancidity, has become a problem of increasing interest in the biological field, because of its proposed role in a variety of pathological conditions. The general mechanism of the process, the formation of toxic aldehydes capable to react with protein and non protein ...
