Pentachlorophenol (PCP) is a potent uncoupler of mitochondrial phosphorylation in vitro and also interferes with microsomal detoxication functions in vitro. This favours flavin mediated oxygenation compared with flavin cytochrome P-450 dependent reactions. Gas chromatographic analysis of subcellular fractions, obtained by zonal centrifugation showed markedly lower PCP concentration in mitochondria and a high accumulation in microsomes compared with cytosol. This increases the likelihood that… CONTINUE READING
