Paper chromatography of cholesterol esters

Journal of Chromatography A, 1963
Abstract A silicic acid paper chromatographic method for the separation of four major classes of cholesterol esters, namely saturated cholesterol esters, cholesterol oleate, cholesterol linoleate and cholesterol linolenate plus cholesterol arachidonate is described. This method uses a benzene-hexane solvent.

HORMONES AND CHOLESTEROL ESTER METABOLISM

Journal of the American Geriatrics Society, 1969
A bstract A study was made of the effects of testosterone, estradiol, ACTH, insulin, epinephrine and l ‐thyroxine on a microsomal preparation of female rat liver esterifying enzyme and cholesterol plus palmitic ...

Serum cholesterol and cholesterol esters in viral hepatitis

The American Journal of Medicine, 1950
Abstract 1.1. Determinations of the partition and amounts of cholesterol and alkaline phosphatase in the serums of 623 patients in the first ten weeks of viral hepatitis were made. 2.2. The serum cholesterol esters were diminished and the serum alkaline phosphatase increased somewhat during the early weeks of the disease.

The Plasma Cholesterol: Cholesterol-Ester Cycle

1983
Three years ago, at the V International Symposium on Atherosclerosis (l), we have presented evidence that both LDL and HDL are metabolic products of the core and surface domains of triglyceride-rich lipoproteins. The data can be summarized as follows: Triglyceride-rich lipoproteins (chylomicrons and VLDL) are primary secretory products of intestinal ...

Cholesterol ester formation in aortas of cholesterol-fed rabbits

Journal of Atherosclerosis Research, 1968
Summary Intravenous injection of [ 14 C]acetate into cholesterol-fed rabbits from which liver, intestine and kidneys had been removed resulted in a rapid incorporation of 14 C into aortic cholesterol ester fatty acids whereas little or no 14 C was incorporated into the non-saponifiable fraction.

Cholesterol ester hydrolysis in aortic tissue

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1973
Abstract The properties of aortic cholesterol esterase have been examined in subcellular fractions of rat and monkey aortic homogenates. Hydrolysis of a variety of labeled cholesteryl esters added as an acetone solution was demonstrated in both microsomal and high speed supernatant fractions.

Aetiology of pulmonary cholesterol-ester granulomas

British Journal of Diseases of the Chest, 1970
Summary A man aged 61 years with chronic myeloid leukaemia was treated with busulphan and developed fibrosing alveolitis and pulmonary cholesterol-ester granulomas. It is considered that the granulomas were related to hyperplasia of granular pneumocytes in the lung and not to pulmonary hypertension.

Determination of cholesterol and cholesterol ester with novel enzyme microsensors

Analytical Chemistry, 1993
Enzyme microsensors using cholesterol oxidase (EC 1.1.3.6) and cholesterol esterase (EC 3.1.1.13) were developed for measuring cholesterol and cholesterol ester. The platinum microsensors (platinum diameter, 50 microns) were etched in hot aqua regia to create a cavity at their tip.

Cholesterol ester hydrolase(s) in mammalian brain: Is there a myelin-specific cholesterol ester hydrolase?

Neurochemical Research, 1986
The present study compared the properties of cholesterol ester hydrolase(s) in myelin and microsomes from rat, mouse and human brain. The results indicated that the enzyme activity in both myelin and microsomes from rat, mouse and human brain was optimal at pH 6.5 and required Triton X-100 for optimal activity. The enzyme activity in myelin was 3- to 4-

Labeling of liver and serum cholesterol esters after the injection of cholesterol-4-C14 and cholesterol-4-C14 esters

Archives of Biochemistry and Biophysics, 1966
Abstract Fasting rats were injected with trace amount of cholesterol-4-C14 and cholesterol-4-C14 esters (palmitate oleate, linoleate and arachidonate) dipersed in rat serum. It was necessary to add an emulsifying agent (Tween 20) to disperse the C14 esters since they do not exchange with lipoprotein cholesterol esters.
