The mechanism of C-4 demethylation during cholesterol biosynthesis
The Biochemical Journal
|July 1, 1975
Abstract:
The conversion of 4,4-dimethylcholest-7-enol into 4alpha-methylcholest-7-enol by rat liver microsomal preparations involves the decarboxylation of a sterol 3-oxo-4alpha-carboxylic acid. By using an (18)O-labelled substrate it was shown that this decarboxylation does not involve a Schiff-base intermediate.
