[Phospholipid composition and fatty acid patterns of isolated phospholipids from rabbit reticulocyte mitochondria].
The phospholipid composition and fatty acid patterns of individual phospholipid classes were determined in mitochondria from rabbit reticulocytes. Compared to mitochondria from rat liver reticulocyte, mitochondria exhibit about twice the amount of phospholipids. The phospholipid pattern of reticulocyte mitochondria (phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol and cardiolipin) is comparable with other mitochondrial species. Mitochondrial fractions from reticulocytes are characterized, however, by an additional content of sphingomyelin. This sphingomyelin differs in its fatty acid composition from the sphingomyelin of the plasma membrane. The fatty acid patterns of all other phospholipids essentially correspond to those of mitochondria from other sources and to those of plasma membranes as well.
