Reduction and esterification of cholesterol and sitosterol by homogenates of feces
Mixtures of cholesterol-1,2-3H and sitosterol-4-14C have been incubated with suspensions of feces in order to compare the behavior of the phytosterol with transformations known to take place with cholesterol under these conditions. Within the limitations of the study, both labeled sterols were ester...
