Popis: The biotransformation of arachidonic acid by rat liver microsomes from both control animals and animals pretreated with known inducers of cytochrome P-450 isoenzymes has been studied using a combination of reversed- and normal-phase high-performance liquid chromatography and combined gas chromatography—electron-impact mass spectrometry. The metabolite profiles observed were found to be dependent upon the inducing agent. Five metabolites were identified, namely 16-, 17-, 18-, 19- and 20-hydroxylated arachidonic acids. Of these the 16- and 17-isomers have not been reported as products of arachidonic acid metabolism by any biological system and the 18-isomer has not been reported as a product of liver metabolism.
