Functional analysis of UDP-sugar: sterol glucosyltransferases [PDF]

Glycosyltransferases (GTs) are essential for the biosynthesis and diversification of many therapeutically important natural products. Of these, UDP-sugar: sterol glucosyltransferases (UGTs) (2.4.1.173) catalyse the synthesis of therapeutically important ...

7α-Hydroxylation of cholestanol by rat liver microsomes

Journal of Lipid Research, 1968
In a study of the mechanism whereby 5α-bile acids are formed from cholestanol, the 7α-hydroxylation of cholestanol was investigated in rat liver preparations in vitro. It was found that in the presence of NADPH and oxygen, rat liver microsomes catalyzed the 7α-hydroxylation of cholestanol to the same extent as that of cholesterol.The rate of the ...

Steroid organoborane reactions [PDF]

Steroid organoboranes have been found to be useful synthetic intermediates. Attempted pyrolyses, based on simple trialkylborane cyclizations, have not yielded C-19 or C-18 functionalized steroids, but have produced isomerized systems not otherwise ...

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

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.
