title: Lipid peroxidation in liver and Ehrlich ascites cell mitochondria.
abstract: Ehrlich ascites cell mitochondria are highly resistant to lipid peroxidation as compared to liver mitochondria from host animals. Succinate protects mitochondria from peroxidative damage, proteins from cross-links, enzymes from inactivation of the enzymes and membranes from permeability changes. The sensitivity of Ehrlich ascites cell mitochondrial membranes to lipid peroxidation is significantly increased in submitochondrial particles. Lipid peroxidation in tumour mitochondrial membranes can not be diminished by succinate as effectively as in liver mitochondria. Ascites cell mitochondria seems to be protected very efficiently from peroxidative damage by a glutathione-dependent mechanism.
