Lipid peroxidation in liver mitochondria from copper-loaded rats. 1985

E Russanov, and P Balevska, and E Ivancheva, and M Kirkova

The amount of phospholipids in liver mitochondria decreased after chronic alimentary copper-loading of rats (40 mg CuSO4 per rat per day in the course of two weeks), while 24 hours after a single intraperitoneal injection of copper (20 mg CuSO4 per kg body weight) it remained unchanged, notwithstanding that both copper treatments highly increased the copper level in mitochondria. Alimentary copper-loading led to a decrease in the relative proportions of the majority of unsaturated fatty acids in mitochondrial phospholipids. Both the spontaneous and Fe2+-induced formation of malonaldehyde were more enhanced in the mitochondria from the two experimental groups as compared to the controls.

UI MeSH Term Description Entries
D008054 Lipid Peroxides Peroxides produced in the presence of a free radical by the oxidation of unsaturated fatty acids in the cell in the presence of molecular oxygen. The formation of lipid peroxides results in the destruction of the original lipid leading to the loss of integrity of the membranes. They therefore cause a variety of toxic effects in vivo and their formation is considered a pathological process in biological systems. Their formation can be inhibited by antioxidants, such as vitamin E, structural separation or low oxygen tension.

D008930 Mitochondria, Liver Mitochondria in hepatocytes. As in all mitochondria, there are an outer membrane and an inner membrane, together creating two separate mitochondrial compartments: the internal matrix space and a much narrower intermembrane space. In the liver mitochondrion, an estimated 67% of the total mitochondrial proteins is located in the matrix.

D010743 Phospholipids Lipids containing one or more phosphate groups, particularly those derived from either glycerol (phosphoglycerides see GLYCEROPHOSPHOLIPIDS) or sphingosine (SPHINGOLIPIDS). They are polar lipids that are of great importance for the structure and function of cell membranes and are the most abundant of membrane lipids, although not stored in large amounts in the system.

D011919 Rats, Inbred Strains Genetically identical individuals developed from brother and sister matings which have been carried out for twenty or more generations or by parent x offspring matings carried out with certain restrictions. This also includes animals with a long history of closed colony breeding.

D005227 Fatty Acids Organic, monobasic acids derived from hydrocarbons by the equivalent of oxidation of a methyl group to an alcohol, aldehyde, and then acid. Fatty acids are saturated and unsaturated (FATTY ACIDS, UNSATURATED).

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
