The effect of chylomicron remnants on bile acid synthesis in isolated rat hepatocytes in monolayer cultures was investigated. Production of bile acids by the cells in the presence of chylomicron remnants at a cholesterol concentration of 7.8-9 nmol/ml was increased by approx. 75% after 17 h and 25% after 24 h incubation. Similar concentrations of cholesterol added to the cells in the form of chylomicrons had no significant effect on bile acid synthesis. These results suggest that cholesterol taken up in chylomicron remnants may be an important source of substrate for bile acid synthesis.

D002914 Chylomicrons A class of lipoproteins that carry dietary CHOLESTEROL and TRIGLYCERIDES from the SMALL INTESTINE to the tissues. Their density (0.93-1.006 g/ml) is the same as that of VERY-LOW-DENSITY LIPOPROTEINS. Chylomicron
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D001647 Bile Acids and Salts Steroid acids and salts. The primary bile acids are derived from cholesterol in the liver and usually conjugated with glycine or taurine. The secondary bile acids are further modified by bacteria in the intestine. They play an important role in the digestion and absorption of fat. They have also been used pharmacologically, especially in the treatment of gallstones. Bile Acid,Bile Salt,Bile Salts,Bile Acids,Acid, Bile,Acids, Bile,Salt, Bile,Salts, Bile
