title: Nature of unsaponifiable lipids of a Mycoplasma strain grown with isopentenyl pyrophosphate as a substitute for sterol.
abstract: Mycoplasma sp., strain J, which is unable to convert mevalonic acid to isopentenyl pyrophosphate (IPP) will grow with IPP as a substitute for sterol. (14)C-labeled IPP is incorporated into its unsaponifiable lipid. This unsaponifiable lipid was separated into three (14)C-labeled fractions, all of which possess spectral and chromatographic characteristics of polyterpenes.
