Selenium Dehydrogenation of Sitosterol

The Story of Beta-sitosterol- A Review

Aims: Phytosterols are a subgroup of the steroids, as an important class of bioorganic molecules, widespread in plants, animals, marines as well as fungi and have similarity to cholesterol in structure. These compounds have a long history of consumption as food or pharmaceutical products, and generally recognized as safe without undesirable side effects. Place and Duration of Study: Medicinal p...

Sluggish sitosterol turnover and hepatic failure to excrete sitosterol into bile cause expansion of body pool of sitosterol in patients with sitosterolemia and xanthomatosis.

Sitosterolemia and xanthomatosis are characterized by the development of tendon and tuberous xanthomas at an early age and premature atherosclerosis despite normal plasma cholesterol concentrations. The reason(s) for the xanthoma formation and premature atherosclerosis are not clearly understood. The accumulation of sitosterol in the tissues of these patients could be due to increased uptake of...

Dehydrogenation of Benzene on Liquid

The reactions of benzene on Al100 + have been investigated as a function of cluster temperature (300−1100 K) and relative kinetic energy (1−14 eV) by low-energy ion-beam methods and mass spectrometry. Benzene chemisorbs on both solid and liquid aluminum clusters to generate Al100C6D6 . A series of Al100−n + (n = 1, 2, 3, ...) products was also observed. As the cluster temperature was raised abo...

Dehydrogenation by Heterogeneous Catalysts

The protective effect of selenium nanoparticles and selenium against paracetamol

Objective(s): Nanotechnology has enabled researchers to synthesize nanosize particles that possess increased surface areas. Compared to conventional microparticles, it has resulted in increased interactions with biological targets.The objective of this study was to determine the protective ability of selenium nanoparticles compared to selenium against parasetamol hepatotoxicity and GPX concentr...
