title: Stereochemistry of hydrogen addition to C-25 of desmosterol by sterol-delta 24-reductase of rat liver homogenate.
abstract: Chemically synthesized (26)- and (27)-methyl-13C-labeled desmosterol (3, 5) were separately incubated with rat liver homogenate. 13C-NMR analysis of the incubation products indicated that the C-25 hydrogen of cholesterol was introduced from the si-face of 3 and the re-face of 5.
