BACKGROUND: Saccharomyces cerevisiae var. boulardii is the only yeast species with probiotic properties. It is considered to have therapeutic significance in gastrointestinal disorders. In the present study, a comparative physiological study between this yeast and Saccharomyces cerevisiae (BY4742) was performed by evaluating two prominent traits of probiotic species, responses to different stress conditions and antioxidant capacity. A global metabolite profile was also developed aiming to identify which therapeutically important secondary metabolites are produced. RESULTS: Saccharomyces cerevisiae var. boulardii showed no significant difference in growth patterns but greater stress tolerance compared to S. cerevisiae. It also demonstrated a six- to 10-fold greater antioxidant potential (judged by the 1,1-diphenyl-2-picrylhydrazyl assay), with a 70-fold higher total phenolic content and a 20-fold higher total flavonoid content in the extracellular fraction. These features were clearly differentiated by principal component analysis and further indicated by metabolite profiling. The extracellular fraction of the S. cerevisiae var. boulardii cultures was found to be rich in polyphenolic metabolites: vanillic acid, cinnamic acid, phenyl ethyl alcohol (rose oil), erythromycin, amphetamine and vitamin B6, which results in the antioxidant capacity of this strain. CONCLUSION: The present study presents a new perspective for differentiating the two genetically related strains of yeast, S. cerevisiae and S. cerevisiae var. boulardii by assessing their metabolome fingerprints. In addition to the correlation of the phenotypic properties with the secretory metabolites of these two yeasts, the present study also emphasizes the potential to exploit S. cerevisiae var. boulardii in the industrial production of these metabolites.

Chemistry is traditionally divided into organic and inorganic chemistry. Recommanded Product: 2926-30-9. The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 2926-30-9

This article describes two coordination polymers based on sodium and nickel triflates, respectively, and the linker adiponitrile (1,4-butanedinitrile). Sodium triflate forms a coordination network with adiponitrile, where the nitriles bridge the sodium ions, a rare coordination mode for a nitrile. Crystal structures of alkali metal complexes of linear aliphatic dinitriles have not been reported previously. With nickel triflate, a cationic 1-D coordination polymer results upon coordination of adiponitrile.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 2926-30-9, you can also check out more blogs about2926-30-9

In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 3105-95-1, name is H-HoPro-OH, introducing its new discovery. Formula: C6H11NO2

Tetramethyl(alky or aryl)cyclopentadienes were synthesized and the organometallic half-sandwich iridium complexes of the form [(eta5-Cp?R)Ir(aa)Cl], Cp?R = tetramethyl(phenyl)cyclopentadienyl (Cp?Ph), tetramethyl(benzyl)cyclopentadienyl (Cp?Bn), tetramethyl(2-propyl)cyclopentadienyl (Cp?iPr), or tetramethyl(cyclohexyl)cyclopentadienyl (Cp?Cy) were prepared and characterized. The complexes adopt a piano stool configuration, forming diastereomers, with ratios similar to reported [(eta5-Cp?)Ir(aa)Cl] complexes. The complexes display an intermolecular hydrogen bonding network in the solid state. These complexes were tested for the asymmetric transfer hydrogenation of several ketones, showing that the R of the Cp?R drastically impacts both selectivity and rate of reaction. Additionally, severe solvent effects are displayed when the reaction media is changed from aqueous to organic solvent.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 3105-95-1 is helpful to your research. Formula: C6H11NO2

Application of 14162-94-8, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.14162-94-8, Name is 4-Chloro-2,2′-bipyridine, molecular formula is C10H7ClN2. In a Article，once mentioned of 14162-94-8

A novel fluorine-18 method employing rhenium(i) mediation is described herein. The method was found to afford moderate to high radiochemical yields of labelled rhenium(i) complexes. Subsequent thermal dissociation of the complexes enabled the radiosynthesis of fluorine-18 labelled pyridine bidentate structures which could not be radiofluorinated hitherto. This rhenium(i) complexation-dissociation strategy was further applied to the radiosynthesis of [18F]CABS13, an Alzheimer’s disease imaging agent, alongside other 2,2?-bipyridine, 1,10-phenanthroline and 8-hydroxyquinoline labelled radiotracers. Computational modelling of the reaction mechanism suggests that the efficiency of rhenium(i) activation may be attributed to both an electron withdrawal effect by the metal center and the formation of an acyl fluoride intermediate which anchors the fluoride subsequent to nucleophilic addition.

A series of platinum(II) complexes of formulae cis-[Pt(Am) 2X2] (where Am represents an inert amine and X a labile (carboxylato) ligand) have been prepared and characterized by elemental analysis, ESI-MS, IR and 1H NMR spectroscopy. The single-crystal molecular structures were determined for cis-[Pt(opea)(cbdca-2H)], cis-[Pt(hmpy)(cbdca-2H)], cis-[Pt(NH3)2(bzmal-2H)] and cis-[Pt(hmpy)(mu-dcch-2H)2] (where opea is picolylamine, hmpy represents 4-hydroxymethylpyridine, cbdca-2H, is 1,1-cyclobutanedicarboxylate anion, bzmal-2H stands for benzylmalonate anion and dcch-2H is trans-1,2-cyclohexanedicarboxylate anion). The interaction of all compounds with DNA was investigated with different techniques: viscosity measurements and emission fluorescence spectroscopy were used to investigate the changes induced by the binding of the platinum compounds to calf-thymus DNA, while atomic force microscopy and electrophoretic mobility allowed evaluating the potential alterations of pBR322 plasmid DNA. The cytotoxic behavior of the platinum compounds on human leukemia HL-60 tumor cell lines was also examined.
