Dihydrocholesterol Chemical Properties,Uses,Production
Description
Cholestanol is a cholesterol metabolite formed by oxidation and an intermediate in the biosynthesis of chenodeoxycholic acid . Cholestanol (10 μg/ml) induces apoptosis in cornea and lens epithelial cells and increases the activity of IL-1β converting enzyme (ICE) and CPP32 proteases. Dietary administration of 1% cholestanol to mice increases serum and liver cholestanol levels and leads to corneal opacities and gallstones and in rats it leads to cholestanol deposition in the cerebellum. Cholestanol levels are increased in plasma of patients with cerebrotendinous xanthomatosis (CTX), a disease characterized by a deficiency in the mitochondrial enzyme sterol 27-hydrolylase (CYP27A1) that leads to progressive neurological symptoms.
Chemical Properties
white powder
Uses
5α-Cholestan-3β-ol is a carbon stanol formed from biohydrogenation of Cholesterol (C432501) in the gut. Studies have also examined the conversion of 5α-Cholestan-3β-ol catalyzed by 3-β-hydroxysteroid dehydrogenase of rat liver.
Definition
ChEBI: A cholestanoid that is (5alpha)-cholestane substituted by a beta-hydroxy group at position 3.
General Description
Cholestanol is a 5α-dihydro derivative of cholesterol. It acts as a marker for cholesterol absorption. Cholestanol is a steroid with 27 carbon atoms.
Purification Methods
Purify 5--cholestan-3-ol via acetylation, crystallisation and de-acetylation, then recrystallisation from EtOH or slightly aqueous EtOH, or MeOH. Its solubility is: 0.5% (MeOH) and 1% (EtOH) at 25o. [Mizutani & Whitten J Am Chem Soc 107 3621 1985.] The acetate has m 114-115o from EtOAc/MeOH and, [] D 20 +13o (c 2, CHCl3). [Bruce & Ralls Org Synth Col Vol II 191 1943, Beilstein 6 IV 3577.]
