If a reducing sugar is present in a solution, addingBenedick's reagentand heating will form an insoluble red precipitate. Non-reducing sugars do not change the colour of the solution, which is blue, and so we have to break the sugar down to monosaccharides by hydrolysis to prove they're n...
reducing sugarscan be determined in an assay containing 2,2′-bicinchoninic acid (BCA). Cu(I), produced from the reduction of Cu(II) by the sugar, forms a deep-blue complex with BCA in alkaline solution. The concentration of the reducing sugar is proportional to the colour intensity[195]...
The paper also includes graphical reports and schematic diagrams showing point of product addition and general refinery flow with reference to practical application of the CarboUA products in several sugar refineries around the world. 展开 关键词: adsorbents CarboUA decolourization sugar refining ...

application of 1.5 mol/L of nitrate increased the pH of the solution of cultured bacteria isolated from saliva that had been incubated with sugar[79]. In clinical trials, 2 weeks of beetroot juice consumption increased the salivary concentrations of nitrate and nitrite and increased the pH ...
“reducing” used herein in the context of scarring refers to an adjustment to the extent of development of scarring, whereby one or more of the colour, contour, rugosity and texture of the healed skin surface approaches measurably closer to that of the patient's normal skin. The expression...
