title: Biochemical controls of liver cholesterol biosynthesis.
abstract: Major endogenous regulatory controls of cholesterol synthesis including dietary-feedback inhibition, circadian rhythms, feeding/fasting fluctuations, and enterohepatic bile acid circulation are discussed in terms of biochemical control mechanisms of liver cholesterol biosynthesis. Other likely control mechanisms such as cofactors, enzyme levels, and enzyme activities are noted. The current state of the biochemical knowledge is very dependent upon integrated data from one experimental animal - the rat. Inferences and implications in the human are thus limited.
