In a study concerned with fate and distribution of 4-C14-cholesterol in the male American cockroach, Periplaneta americana (L.), it was found that nearly all of the radioactive sterol fraction, even at 20 days after administration, behaved like unchanged cholesterol when analyzed by gas-liquid chromatography and reverse isotope dilution (Ishii et al. 1963). These results differ from those of Agarwal and Casida (1900), who report that the nymphs of this insect convert 4-14-cholesterol to their major natural sterol, a compound of unknown structure. This sterol differs from cholesterol in its chromatographic behavior in that it is slightly less polar. When adult American cockroaches were fed C14-cholesterol or its acetate, the major C14 sterol was again found to be eluted in a position similar to but not necessarily identical with cholesterol (Agarwal 1961). |
