Fatty acid composition (mol%) of mitochondrial membrane phospholipids.

Data correspond to the mean of values obtained in two independent preparations. Differences between values of every couple were less than 10%. Fatty acids were extracted from mitochondrial membrane phospholipids after saponification. After derivatization with methanolic boron trifluoride, fatty acid methyl esters were separated by gas-liquid chromatography and identified by using known standards.U.I., Unsaturation index, Σ mol% of each fatty acid x number of double bonds of the same fatty acid; ND, not detected.
