Objective: analyze and evaluate scientific literature data on the need for use of plant sterols stanols treatment hypercholesterolemia in order to reduce risk coronary heart disease. Materials methods. The article summarizes information publications journals search systems PubMed, Scopus, Google Scholar, as well library databases (eLibrary). Results. Phytosterols (phytosterols), phytostanols, a...
A convenient synthesis of sidechain-modified phytosterols is achieved via a temporary masking of the stigmasterol 5,6-alkene as an epoxide. Following performance of the desired modification, the alkene is regenerated through a mild deoxygenation. The approach is applied to the syntheses of β-sitosterol and campesterol acetate, and suggests a facile route to the (Z)-isomers of Δ22–23
Supercritical carbon dioxide (SC-CO,). fractionation technique was evaluated as an altemativeprocess for reducing the free-fatty-acid (FFA) content and minimizing the phytosterolloss of rice bran oil (REO) during the process. The effects of pressure (20.5 to 32.0 MPa) and temperature (45 to 80 DC) for isothermal operation of the column on the composition of the resultant fractions were exarnine...
Microbial transformation of hydrophobic phytosterols into the pharmaceutical steroid precursors AD (androst-4-ene-3, 17-dione) and ADD (androst-4-diene-3, in a water–plant oil two-phase system by Mycolicibacterium neoaurum is paradigm interfacial biocatalysis Pickering emulsions stabilized bacterial cells. In present work, phase inversion emulsions—i.e., turning from water-in-oil (W/O) oil-in-w...
BACKGROUND Phytosterols are plant-derived sterols that are taken up from food and can serve as biomarkers of cholesterol uptake. Serum levels are under tight genetic control. We used a genomic approach to study the molecular regulation of serum phytosterol levels and potential links to coronary artery disease (CAD). METHODS AND RESULTS A genome-wide association study for serum phytosterols (c...
