7-Dehydrostigmasterol and ergosterol: the major sterols of an amoeba.
The sterol fraction of Acanthamoeba (Neff) contains 60% 7-dehydrostigmasterol and 40% ergosterol. The sterols were characterized by infrared and ultraviolet spectroscopy, gas chromatography, specific reactions, and mass spectral analysis. Sterols constitute 5% of the lipids and 15% of the neutral lipids in this species.
