Methyl malondialdehyde as an internal standard for the determination of malondialdehyde
Journal of Chromatography B: Biomedical Sciences and Applications, 2001Methyl malondialdehyde (Me-MDA) is suggested as an internal standard for the determination of the lipid peroxidation product, malondialdehyde (MDA). A procedure for synthesising the Me-MDA sodium salt is described in detail. The purity and identity of the synthesised Me-MDA have been confirmed using nuclear magnetic resonance and UV spectroscopy, and ...

Malondialdehyde, modified lipoproteins, and atherosclerosis
European Heart Journal, 1990It is likely that identification of the mechanisms releasing malondialdehyde and other peroxidative decomposition products in the arterial wall will provide new insights into the sequence of biochemical and cellular events in the pathogenesis of atherosclerosis and ultimately may lead to development of strategies for the intervention and reduction of ...

Malondialdehyde Derivatives in Urine
1988Malondialdehyde (MDA) excretion in rat urine is responsive to peroxidation of dietary lipids and to factors which increase lipid peroxidation in vivo: vitamin E deficiency and administration of iron, CCI4 or adriamycin. Urinary MDA is also increased by administration of the lipolytic hormones ACTH and epinephrine and by fasting, particularly when the ...

The aim of this study was to validate, by capillary electrophoresis, the use of synthesized methyl malondialdehyde as the internal standard for the direct quantification of free and total (free+bound) malondialdehyde in biological samples. All analyses were performed in 20 cm x 50 microm uncoated capillaries at 20 degrees C, using 25 mmol/L borax (pH 9.

Proceedings of the Virtual 2021 AOCS Annual Meeting & Expo, 2021
The reactivity of malondialdehyde in saturated glycerol triheptanoate oil was studied over a wide temperature range (298.15-453.15 K). With respect to the non-ideal character of a lipid medium, a kinetic model was proposed that described the experimental malondialdehyde data by a reversible hydrolytic cleavage and an irreversible aldol self ...

The Analyst, 2011
Malondialdehyde (MDA) has become a well-established biomarker for oxidative stress. The most commonly used way to determine urinary MDA levels is the thiobarbituric acid (TBA) assay, which suffers from several drawbacks. In this manuscript, we describe a novel derivatization strategy for the highly sensitive and selective fluorescence-based ...

Electronic spectroscopy of malondialdehyde
Chemical Physics Letters, 1976Abstract The electronic absorption spectra of malondialdehyde in vapor and solutionphases and derived monoanion in solution are presented. Comparison of CNDO/s-CI computations with experiment allows two singlet—singlet transitions at λ ⩾ 1800 A to be assigned within the G 4 molecular symmetry group description of the planar non-rigid neutral ...

Malondialdehyde formation in stored plasma
Biochemical and Biophysical Research Communications, 1980Summary The formation of malondialdehyde in plasma during storage was used as an indicator of lipid peroxidation. Malondialdehyde concentrations were measured in plasma stored at 4°C in the presence of various preservative reagents. A rapid rate of formation of malondialdehyde (15.0 ± 14.0 nmol/dl/week) was observed in control plasma preserved with ...

Ascorbate and malondialdehyde in stroke patients
Irish Journal of Medical Science, 1994It is believed that free radical formation and subsequent oxidative damage in the form of lipid peroxidation may be a factor in the cerebral damage secondary to the ischaemia of a cerebrovascular accident (CVA). Total serum ascorbate and malondialdehyde (MDA) were measured in 45 patients with CVA on the day of admission to hospital (Time 0) and 48 ...

Solid-Phase Extraction in Malondialdehyde Analysis
Analytical Biochemistry, 1997Malondialdehyde (MDA) has been widely used as an index of lipoperoxidation in biological and medical sciences as well as in the food industry. A solid-phase extraction (SPE) of the condensation product of the MDA with 2-thiobarbituric acid (TBA) was developed using LiChrolut C18ec, 200 mg (Merck, Darmstadt, Germany), as a SPE cartridge and methanol as ...
