In the paper there is considered the question of the influence of temperature on the course of the early stages of degradation D-glucose in aqueous solutions in pH range 1,0–7,0. By Raman spectroscopy there is demonstrated that within the temperature limi... see more

In the paper there is considered the question of the influence of hydrogen-ions concentration on the formation of intermediates (unsaturated carbonyl-containing compounds with Lambdamax225 nm and carbonyl-containing compounds with Lambdamax285 nm) of the ... see more

A suitable and effective scheme for the synthesis of 3,7-disubstituted [1,2,4]triazolo[4,3-a]pyrazin-8(7H)-ones has been suggested and tested. It can provide a wide chemical diversity of the final products containing practically any substituent in positio... see more

During the prevention and treatment of cardiovascular diseases, first cause of deaths in the world, diet has a vital role. While nutrition programs for the cardiovascular health generally focus on lipids and carbohydrates, effects of proteins are not well... see more

Volatile compounds are produced in wines during fermentation, distillation and ageing in oak barrels. Even if the wine volatile profile is extremely complex, containing more than 800 compounds, only 50 have an impact on wine quality (Colibaba 2009). Belon... see more

The seeds of Areca nut plants hold significant economic value, with a remarkable total production of 65,295.89 tons. However, the husk, constituting 50% to 75% of the fruit, are persistently discarded. This study aims to explore the conversion of Areca nu... see more

A synthetic approach to furyl- and benzofuryl-containing building blocks utilizing easily accessible substrates is reported. Cascade acid-catalyzed reactions of 2-methylfuran with a,ß-unsaturated carbonyl compounds or salicyl alcohols followed by oxidatio... see more

The work is devoted to the synthesis of new pyrrolo[2,3-d]pyrimidine-containing a-hydroxyphosphonic acids as precursors for the synthesis of potential biologically active compounds. The reaction between methyl 7-allyl-1,3dimethyl-2,4-dioxo-2,3,4,7-tetrahy... see more
