Objectives . A key step in the synthesis of natural nucleoside analogs is formation a glycosidic bond between carbohydrate fragment and heterocyclic base. Glycosylation methods differ terms regio- stereoselectivity. promising method for highly specific new pharmacologically active compounds involves an enzymatic reaction catalyzed by genetically engineered phosphorylases. This study devoted to ...

In expert opinions about poisonings by inorganic compounds, difficulties may arise that are associated with unavailability of data on concentrations of metals and non-metals in various biological materials, occurring normally and in poisoning cases, lack of appropriate material for analysis and lack of screening methods of analysis. Furthermore, the nature of the inorganic compound itself, its ...

Biochemical, volatile and textural profiles during manufacture and ripening were determined in samples of Castelmagno PDO cheese obtained from three different batches in the main artisan cheese plant of Castelmagno PDO production area. At the end of manufacture, samples were characterised by a pH of 6.57% and 52.4% moisture content. The HPLC analysis of organic acids and sugars showed the exhau...
