Distribution of labeled cholesterol in animal tissues
Rats were fed single doses of cholesterol-4-C14 and sacrificed at various time intervals. In another experiment, rabbits were injected intravenously with lipoproteins labeled with cholesterol-4-04 obtained from a donor animal and sacrificed at various time intervals. The ratios between specific radioactivities of cholesterol in several tissues and that in the serum were determined and followed ...
متن کاملIntestinal cholesterol esterase: intracellular enzyme
The location of cholesterol esterase in rabbit intestine was re-evaluated. In three different experiments that were designed to eliminate contaminating mucus and pancreatic enzymes from the lumen of the small intestine, it was observed that the activities of cholesterol esterase and amylase in intestinal cytosol and whole homogenate decreased in parallel fashion. After the mucus was carefully w...
متن کاملCholesterol esterases: IV. Cholesterol esterase of rat intestinal mucosa.
Nieft and Deuel (1, 2) found that in rat liver and intestinal mucosa two different opposing systems were responsible for the synthesis and hydrolysis of cholesterol esters. The esterifying system required the presence of phosphate ion and a fatty acid source. The hydrolytic system consisted of at least two factors and its activity was accentuated by soy bean lecithin. While their extracts were ...
متن کاملRegulation of neutral cholesterol esterase activity
The effect of phospholipids on cholesteryl ester hydrolysis by neutral cholesterol esterase in alveolar macrophages was studied. Among the phospholipids used as emulsifiers, those with a negative charge, such as phosphatidylserine, phosphatidic acid, phosphatidylinositol, and cardiolipin, gave a higher level of hydrolysis by neutral cholesterol esterase than other less negatively charged phosph...
متن کاملPhosphorus Compounds in Animal Tissues
The concept that nucleic acids are intimately associated with fundamental cellular processes has gained considerable favor within the last few years. This can undoubtedly be attributed to the researches of Caspersson and his associates. Caspersson, with the aid of ultraviolet spectrophotometry, has been able to measure the nucleic acids in various parts of the cell under a variety of experiment...
