[Degradation of 4,9-dichlorodibenzodioxin in rat liver microsomes].
The rat liver microsomal cytochrome P 450 was established to dechlorinate 4,9-dichlorodibenzodioxin into 4,9-dihydroxydibenzodioxin. Two isoforms of this cytochrome P 450 were electrophoreticaly identified and quantified. 4,9-dihydroxidibenzodioxin transforms into resorcin with the help of ascorbic acid.
