Isolation of Cholesterol Sulfate from Bovine Adrenals
the spectra illustrated in Fig. 1 confirm the identity of the isolated material. The salt was hydrolyzed by dissolving the sample in 20 ml of tetrahydrofuran containing perchloric acid (5). After 3 hours at 50”, the solution was brought to neutrality with concentrated NH*OH and the tetrahydrofuran was evaporated under vacuum at 45”. The residue was then partitioned between water and ether, and ...
متن کاملUse of ferric ammonium sulfate in serum cholesterol determination.
To determine cholesterolin biologicalfluids,use of the ferric chloride-sulfuric acid reagent introduced by Zlatkis et al. (1) is relatively simple and reliable (2, 3), and the sensitivityof the reagent for cholesterol is four to five times greater than that of the Liebermann-Burchard reagent (2). However, Parekh and Jung (4) reported that hydrogen chloride is evolved during the ferric chloride-...
متن کاملInhibition of proteases involved in embryo implantation by cholesterol sulfate.
BACKGROUND Matrix metalloproteinases (MMPs) and the plasminogen activator (PA)/plasmin system are two major groups of proteases involved in the matrix degradation required for embryo implantation. We previously showed that the content of cholesterol sulfate (CS) in rabbit endometrium increases characteristically during the implantation period. Furthermore, CS has been reported to inhibit serine...
متن کاملCholesterol sulfate: a new adhesive molecule for platelets.
BACKGROUND Cholesterol 3-sulfate is present on a variety of cells and in human LDL, and it has been found in atherosclerotic lesions of human aorta. Its precise biological role has not yet been described. METHODS AND RESULTS In this study, we investigated the interaction of platelets with cholesterol sulfate. Platelets adhered in a concentration-dependent and saturable manner to cholesterol s...
متن کاملCholesterol sulfate in human physiology: what's it all about?
Cholesterol sulfate is quantitatively the most important known sterol sulfate in human plasma, where it is present in a concentration that overlaps that of the other abundant circulating steroid sulfate, dehydroepiandrosterone (DHEA) sulfate. Although these sulfolipids have similar production and metabolic clearance rates, they arise from distinct sources and are metabolized by different pathwa...
