摘要：

The lipid composition and certain structural and functional features of liver and heart mitochondria and microsomes were investigated in pigs fed diets containing 0, 15 and 30% Toprina (dried biomass of C. lipolytica grown on n-alkanes). The presence of Toprina in the diets and its odd-chain higher fatty acids (HFA) (especially 17:1 and 17:2) in total lipids, phospholipids and neutral lipids of pig liver and heart mitochondria and microsomes does not result in any variations of membrane fluidity (evaluated by the unsaturation index, the unsaturation index/% of total saturated HFA and by fluorescence polarization of perylene), nor does it result in changes of mitochondrial ATPase activity, sensitive to membrane lipid composition.
