Chondroitin sulfates are linear sulfated polysaccharides called glycosaminoglycans. They are important nutraceutical and pharmaceutical products that are biosynthesized through the action of chondroitin sulfotransferases on either an unsulfated chondroitin or a dermatan polysaccharide precursor. While the enzymes involved in the biosynthesis of chondroitin sulfates are well known, the cloning e...

Tydemania expeditionis Weber-van Bosse (Udoteaceae) is a weakly calcified green alga. In the present paper, liquid chromatography coupled with photodiode array detection and electrospray mass spectrometry was developed to identify the fingerprint components. A total of four triterpenoid sulfates and three hydroxy fatty acids in the ethyl acetate fraction of the crude extract were structurally c...

The binding data for interaction of a homologous series of n-alkyl sulfates with alkyl chainlengths from C8 to C12 with insulin were analyzed on basis of Hill equation for two classes ofbinding sites .The intrinsic Gibbs free energies were calculated and resolute on basis ofelectrostatic and hydrophobic contributions The estimation of these contributions reveals themajor role of electrostatic i...

Untargeted metabolomics identified urinary biomarkers able to discriminate between the intake of fresh hand-squeezed and industrially processed orange juices. Processing led an upregulation in excretion hydroxy-polymethoxyflavone sulfates, abscisic acid, sinapic acid 4′-glucuronide. The demethylated polymethoxyflavone metabolites were produced with a significant interindividual variability sugg...

The oxidation of sulfide minerals in coal and mine's waste materials produce acid mine drainage. The evaporation, oxidation, dilution and neutralization of this acid drainage lead to formation of secondary minerals. Due to having broad surface spreading these minerals have the potential of maintaining sulfates and many of the metallic elements. In order to carry out mineralogical and geochemica...
