โฆ Synopsis
The present paperdealswiththebiosynthesis,absorptionand tissuedistribution,and the originofsterols in the crabs, Cal2cermajester.Aftertheadministration of isotopic mevalonate and isotopic cholesterol to crabs, the sterols were isolated by the digitoninemethod.Theidentificationand sterol compositions were determined by gas-liquid chromatography, and gas chromatography-mass spectrometry.The results indicated that C. majester fail toutilize mevalonate to synthesize cholestero1,and are incapable of the bioconversion of cholesterol to other sterols. The sterols found in their tissues may originate from dietary sources.
