results showed ( 1 ) that bile free [ 14c ] cholesterol secretion was a constant and linear proportion of the whole liver free [ 14c ] cholesterol pool , ( 2 ) that secretion into bile of free [ 3h ] cholesterol was in direct proportion to the rate of hydrolysis of hepatic [ 3h ] cholesteryl esters , and ( 3 ) that rates of biliary cholesterol secretion were very similar when secretion was calculated using the specific activity of free [ 14c ] cholesterol and free [ 3h ] cholesterol in the entire liver to 'label ' the precursor free cholesterol pool .
