Aplicación

Brassicasterol was used as standard to analyze the sterols from mussels sample by thin layer chromatography.

Acciones bioquímicas o fisiológicas

Brassicasterol is a plant sterol, structurally similar to cholesterol. Plant sterols compete with cholesterol and reduce the content of cholesterol incorporated into micelles thereby reducing its absorption. Brassicasterol reportedly decreases the progression of atherosclerosis. The level of brassicasterol in cerebrospinal fluid may be used as a prognostic factor for progression of Alzheimer′s disease.
Brassicasterol is a phytosterol found in rapeseed and canola oils; it is also present in marine algae and shellfish. Brassicasterol has been shown to inhibit sterol Δ24-reductase, an enzyme involved in the mammalian cholesterol biosynthesis pathway.

Nota de preparación

Brassicasterol is from a semi-synthetic source. It yields clear, colorless solution in chloroform at 50 mg/ml.

Cholesterol Biosynthesis Regulation

The amount of cholesterol that is synthesized in the liver is tightly regulated by dietary cholesterol levels. LDL receptors regulate the cellular transport of lipid rich low density lipoprotein (LDL) particles.
