Evidence for the importance of iron in the alpha-oxidation of 3-methyl-substituted fatty acids in the intact cell.


Preincubation of isolated rat hepatocytes with desferrioxamine or o-phenanthroline, two iron-specific chelators, strongly suppressed the CO2-production from the alpha-oxidation of 3-methylmargaric acid, whereas the beta-oxidation of 2-methylpalmitic acid, palmitic acid, trihydroxycoprostanic acid and the conversion of formic acid to CO2 were not affected… (More)
