RESUMO

Adult human brain contains cholestanol and two series of cholesterol precursors having 30, 29, 28, and 27 carbon atoms; one has an unsaturated steroid nucleus, and the other is unsaturated in both nucleus and side chain. The ability of preparations of brain to incorporate a specific precursor into cholesterol, as well as into these sterol metabolites in vitro, indicates that cholesterol synthesis continues long after brain maturation ceases.

RESUMO

A chromatographic method, using columns packed with Celite-Silica Gel G impregnated with silver nitrate, has been developed for the separation of cholesterol from desmosterol (24-dehydrocholesterol).The system employed allows a complete separation of the two sterols as acetates, as determined by gas-liquid chromatography and thin-layer chromatography.The recovery of pure cholesterol and desmosterol is quantitative.
