[4-14C]Cholesteryl oleyl ether-labeled chylomicron remnants were injected into rats which received a specific goat antibody against rat hepatic lipase or a control serum. Chylomicron remnant cholesterol ether disappeared from circulation with a significantly higher half-life (2-fold) in antibody-treated rats than in controls (P less than 0.001). Recovered radioactivity in the liver was 2-fold lower in antibody-treated rats (22.8% (n = 6) vs. 45% (n = 4) P less than 0.01). These results clearly show that hepatic lipase may strongly promote chylomicron remnant cholesterol ether uptake by the liver.

UI MeSH Term Description Entries
D008049 Lipase An enzyme of the hydrolase class that catalyzes the reaction of triacylglycerol and water to yield diacylglycerol and a fatty acid anion. It is produced by glands on the tongue and by the pancreas and initiates the digestion of dietary fats. (From Dorland, 27th ed) EC 3.1.1.3.

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.
