Synthesis of 24-heteroatom-substituted cholestanols

open access: yesJournal of Lipid Research, 1988
Short syntheses of 24-thia-5 alpha,20 xi-cholestan-3 beta-ol, 24-methyl-24-aza-5 alpha,20 xi-cholestan-3 beta-ol, and 24-nor-5 alpha,20 xi-cholan-3 beta-ol from 3 beta-hydroxy-5 alpha-pregnan-20-one are described. The products and synthetic intermediates

Synthesis of conjugated cholesterol and cholestanols.

open access: yesChemical and Pharmaceutical Bulletin, 1979
The glucuronides, sulfates, glucosides and N-acetylglucosaminides of cholesterol and epimeric 5α-cholestan-3-ols have been synthesized. The formation of a β-glucoside linkage was readily achieved by means of the Koenigs-Knorr reaction with the corresponding α-acetohalosugar, employing cadmium carbonate as a catalyst.

Relation of sterol structure to utilization in pleuropneumonia-like organisms

open access: yesJournal of Lipid Research, 1964
Six sterols, Δ5-cholesten-3Β-ol (cholesterol), Δ5-cholesten-3α-ol, cholestan-3Β-ol, cholestan-3α-ol, coprostan-3Β-ol, and coprostan-3α-ol, selected to represent variations in the configuration of the A and B rings and of the 3-hydroxyl group, were tested

Crystal structure of cholestanyl caprylate and binary phase behavior with cholesteryl caprylate.

open access: yesJournal of Lipid Research, 1991
The crystal structure of cholestanyl n-octanoate (caprylate) (C35H62O2) is monoclinic with space group A2 and cell dimensions a = 10.103(7), b = 7.646(7), c = 87.63(7) A, beta = 90.51(6) degrees; Z = 8 [two molecules (A, B) in asymmetric unit], V = 6769 ...

OH-Initiated Heterogeneous Oxidation of Cholestane: A Model System for Understanding the Photochemical Aging of Cyclic Alkane Aerosols

open access: yes, 2016
Aerosols containing aliphatic hydrocarbons play a substantial role in the urban atmosphere. Cyclic alkanes constitute a large fraction of aliphatic hydrocarbon emissions originating from incomplete combustion of diesel fuel and motor oil.

Preparation and determination of configuration of 3-halogeno-3-methyl-5 alpha-cholestane epimers

open access: yes, 1986
3α- Chloro- 3β- methyl - and 3β- chloro- 3α- methyl - 5α- cholestane were prepared by reaction of hydrochloric acid with the two epimeric 3- hydroxy-3-methyl-5α-cholestanes.

On the Conversion of Cholestanol into Allocholic Acid in Rat Liver [PDF]

open access: yesEuropean Journal of Biochemistry, 1971
The early steps in the conversion of cholestanol into allocholic acid were studied in homogenates of rat liver. The 20000 ×g supernatant fluid was found to catalyze 7α‐hydroxylation of cholestanol. Under the same conditions 7α‐hydroxylation of 5α‐cholestan‐3α‐ol and 5α‐cholestan‐3‐one was insignificant.

The Metabolism of Cholestanol, Cholesterol, and Bile Acids in Cerebrotendinous Xanthomatosis [PDF]

open access: yesJournal of Clinical Investigation, 1973
The metabolism of cholesterol and its 5-dihydro derivative, cholestanol, was investigated by means of sterol balance and isotope kinetic techniques in 3 subjects with cerebrotendinous xanthomatosis (CTX) and 11 other individuals. All subjects were hospitalized on a metabolic ward and were fed diets practically free of cholesterol and cholestanol. After

Deposition of Cholesterol and Cholestanol in Experimental Rabbit Atherosclerosis.

open access: yesExperimental Biology and Medicine, 1961
SummaryContrary to the original findings it is established that cholesterol-C14 and cholesterol-H3 are deposited in tissues of rabbits in exactly the same way. The reason for the discrepancy in deposition of the two substances in earlier experiments was found in the presence of chemically negligible traces of cholestanol-H3 which had then not been ...
