title: Arachidonic acid epoxygenase: detection of epoxyeicosatrienoic acids in human urine.
abstract: Epoxyeicosatrienoic acids, metabolites of the cytochrome P-450-mediated epoxygenase reaction, were detected in human urine by gas chromatographic-mass spectroscopic techniques after conversion to their hydrogenated and non-hydrogenated methyl and pentafluorobenzyl esters. Initial analysis of the regioisomeric composition utilizing the corresponding hydrogenated pentafluorobenzyl esters revealed the presence of the 8,9- and 14,15-isomers.
