A very simple and dirrct radioactive isotope m&hod has been tlwcl~ibed for the quantitative determination of reducing sugars. The method can be adapted to give any degrtte of sensitivity desired. The procedure is of general applicability to the determination of a large class of sugars. The stoichiometry of the reaction makes it a comprehensive procedure which greatly facilitates the analysis of...

Effects of zeatin on amino acid and sugar contents of detached radish (Raphanus sativus L.) cotyledons were investigated to determine if accumulation of these solutes contributes to cytokinin-enhanced growth. Protein and amino acid levels were not significantly affected, but in cotyledons incubated in light the hormone caused greater accumulations of reducing sugars than occurred in light contr...

the aim of the present study was to compare three reducing sugars (d-glucose, d-arabinose, d-mannose) with respect to the antioxidative activity characteristics of their caramelisation products (cps) prepared by monitoring uv-absorbance, browning intensity, ferric ion reducing capacity, fe2+ ion chelating activity as well as dpph radical scavenging activity. moreover, the effect of cps from d-g...

A NEW MICRO-ANALYTICAL SYSTEM FOR REDUCING SUGARS APPLICATIONS TO SEDIMENT AND SEAWATER

LTHOUGH many substances have been shown to increase iron ahsorption, the mechanism of this action is obscure. Fructose, for example, increases iron absorption in rats, and it has been suggested that its effect depends on its ability to chelate iron.4 We proposed to test this hypothesis, and to in ’estiga e possible relationships between the effects of various metabolic substrates and reducing a...

Fatty liver disease affects up to one out of every two adults in the western world. Data from animal and human studies implicate added sugars (eg, sucrose and high-fructose corn syrup) in the development of fatty liver disease and its consequences. Added fructose in particular, as a component of added sugars, may pose the greatest risk for fatty liver disease. Considering that there is no requi...

Decreasing oil reserves, the need to reduce CO2 emissions and increasing energy demand are issues that are forcing scientists to search for new opportunities in the field of energy. As a result, biofuels have been considered as one possible solution to solve part of these challenges. This research is one small part of that effort. For both human and economic reasons the use of edible raw materi...

THE use of ferricyanide for the quantitative estimation of sugar was introduced by Hagedorn and Jensen [1923]. Their method has been extended to other sugars by Hanes [1929] and Hulme and Narain [1931]. These methods involve a preliminary heating for 15 minutes and a subsequent back titration. The fact that ferricyanide is only slightly coloured would seem to make it valueless for a direct titr...

We reported previously the finding by paper chromatography of reducing sugars in the urines of 24 out of 50 normal full-term babies (Haworth and McCredie, 1956). We suggested that the galactose which we found in the urines of 13 of the 50 babies might be related to the functional inefficiency of the liver that is so commonly a feature of the newborn. If this were so it might be expected that pr...
