Equilibration of 24,25-dibromides of lanosterol and derivatives

Journal of the Chemical Society, Perkin Transactions 1, 1972
Bromination of lanosteryl acetate under conditions of kinetic control gives two 24,25-dibromides. A and B, in equal amounts. Thermodynamically controlled equilibration of these dibromides results in a 5:1 mixture of the two. The driving force is considered to be interaction between the 20-methyl group and the 24-bromine atom in the 24R-configuration ...

Epoxides of lanosterol and some related compounds

Journal of the Chemical Society, Perkin Transactions 1, 1972
A convenient method for the separation of the two isomers of 24ξ,25-epoxy-5α-lanost-8-en-3β-yl acetate is described. The absolute configuration of these compounds is established by their conversion into the corresponding 5α-lanost-8-ene-3β,24ξ-diol 3-acetates, and thence by Horeau's method (treatment with α-phenylbutyric anhydride), and by the method ...

Cholesterol Biosynthesis: Lanosterol to Cholesterol

Journal of Chemical Education, 2002
Cholesterol is an important biochemical, medical, and commercial molecule. In the pathway for cholesterol biosynthesis, biochemistry textbooks discuss the synthesis of lanosterol from acetate in detail. However, the conversion of lanosterol to cholesterol is most often simply indicated as a multistep process, without elaboration.

Is exogenous lanosterol a micronutrient?

Physiological chemistry and physics, 1982
Lanosterol, a precursor of cholesterol, is ingested with human diet and occurs in the body in concentrations exceeding solubility. Flesh of immature animals is a common source of dietary lanosterol, which may form with cholestanol and water an insoluble adjunct, CL-2W.
