Abstract
BIOSIS COPYRIGHT: BIOL ABS. The lipid peroxidation products formed from arachidonic acid, linolenic acid, linoleic acid, oleic acid, and their esters upon Fe2+2O2 oxidation were analyzed by two derivatization methods. alpha,beta-Unsaturated aldehydes, such as acolein and 4-hydroxy-2-nonenal, and beta-dicarbonyl compounds, such as malonaldehyde, were derivatized with N-methylhydrazine. Saturated normal aldehydes, such as formaldehyde and hexanal, were derivatized with cysteamine. Subsequently, a specific quantity of each derivative 1-methylpyrazoline, 1-methylpyrazole, and thiazoline was analyzed by gas chromatography. Formaldehyde, which has never been quantified satisfactorily in a lipid peroxidation system, was the major product, and its quantities ranged from 142 nmol/mg in ethyl linolenate to 50 nmol/mg in ethyl arachidonate. Malonaldehyde was found in all samples, in levels between trace in oleic acid and 97 nmol/mg in ethyl arachidonate. 4-Hydroxy-2-nonenal was found in arachidonic and linole
