The concentration-dependence of tert-butyl hydroperoxide (BHP) inhibitory effect on oxygen consumption in isolated rat liver mitochondria was measured in the presence of various respiratory substrates. Strong inhibitory effect at low concentrations of BHP (15-30 µM) was found for oxoglutarate and palmitoyl carnitine oxidation. Our data indicate that beside peroxidative damage of complex I also various mitochondrial NADH-dependent dehydrogenases are inhibited but to a different extent and with different kinetics. Our data also show that succinate could be an important nutritional substrate protecting hepatocytes during peroxidative damage
