	Cholesterol and Bile Metabolism
		Cholesterol is an extremely important biological molecule that has roles in membrane structure as well as being a precursor for the synthesis of the steroid hormones and bile acids.
		Cholesterol is transported in the plasma predominantly as cholesteryl esters associated with lipoproteins.
		However, the excretion of cholesterol in the form of bile acids is insufficient to compensate for an excess dietary intake of cholesterol.
