Fatty acids of mitochondrial membranes from Tetrahymena pyriformis
FK Gleason
We have examined the fatty acid composition of the mitochondrial membranes
in three strains of Tetrahymena pyriformis. All three had similar
components and exhibited large amounts of unsaturated fatty acids. The
cytoplasmic mutant, CA-10, which has a slower growth rate and unusual
membrane morphology, had a slightly higher amount of iso- acids but was
otherwise similar to the other strains in fatty acid composition.
Arachidonic acid, previously undetected in extracts of Tetrahymena, was
identified as a minor component of the mitochondrial membrane.
