reaction mechanismssustainable chemistryA joint experimental and computational study on the glucose–fructose conversion in water is reported. The reactivity of different metal catalysts (CrCl3, AlCl3, CuCl2, FeCl3, and MgCl2) was analyzed. Experimentally, CrCl3 and AlCl3 achieved the best glucose ...
FructoseReuseHerein, the environmentally friendly Fe/β zeolite for glucose isomerization to fructose in aqueous media was reported for the first time. The effects of various reaction conditions including reaction temperature, reaction time, catalyst dosage, etc. on the isomerization reaction over Fe/β...
Changes in the glucose: Fructose ratio during the growth period of the razaki grape The fructose content of table grapes is of importance, especially for cultivars growing in cold climates. The glucose: fructose ratio (G: F ratio) in the t... TP Soulis,AS Avgerinos - 《Journal of the ...
29% fructose yield was found with 68% fructose selectivity, at 90 °C for an 8 h reaction in aqueous solution. The catalytic activity of KMnO4 was correlated with its Lewis acidity. The outcomes of these experiments provided a better understanding of sugar transformations in the KMnO4 aqueous ...
This paradox results because fructose bypasses the rate-limiting step of glycolysis and uses a rapid ATP-requiring reaction that abruptly depletes ATP and provokes a compensatory rise in AMP. Thus, fructose has the opposite effect of glucose on the AMPK/malonyl-CoA signaling system and thereby, ...
Catalytic conversion of fructose and sucrose to 5-hydroxymethylfurfural using simple ionic liquidDMF binary reaction media 热度: Short-term dietary supplementation with fructose accelerates gastric emptying of a fructose but not a glucose solution
to achieve the selective transformation of fructrose or fructose precursors sucrose or inulin into 5-hydroxymethylfurfural in water as the solvent.2-4 However, specific properties of the catalyst (controlled acidity, crystallinity, micropore volume) were required for the reaction to take place with a...
The invention relates to a fructose glucose syrup separation technology and aims at providing a region selective control method and device for preparing fructose glucose syrup by integrated reaction. The method comprises the following steps of: sending a product after enzyme isomerization and post-...
