Intestinal D-fructose absorption in 31 children was investigated using measurements of breath hydrogen. Twenty five children had no abdominal symptoms and six had functional bowel disorders. After ingestion of fructose (2 g/kg bodyweight), 22 children (71%) showed a breath hydrogen increase of more than 10 ppm over basal values, indicating incomplete absorption: the increase averaged 53 ppm, ra...

In search of an adequate model for the human metabolic syndrome, the metabolic characteristics of Wistar rats were analysed after being submitted to different protocols of high fructose ingestion. First, two adult rat groups (aged 90 d) were studied: a control group (C1; n 6) received regular rodent chow (Labina, Purina) and a fructose group (F1; n 6) was fed on regular rodent chow. Fructose wa...

AIMS In animals, intracerebroventricular glucose and fructose have opposing effects on appetite and weight regulation. In humans, functional brain magnetic resonance imaging (fMRI) studies during glucose ingestion or infusion have demonstrated suppression of hypothalamic signalling, but no studies have compared the effects of glucose and fructose. We therefore sought to determine if the brain r...

Rapid proliferation and Warburg effect make cancer cells consume plenty of glucose, which induces a low glucose micro-environment within the tumor. Up to date, how cancer cells keep proliferating in the condition of glucose insufficiency still remains to be explored. Recent studies have revealed a close correlation between excessive fructose consumption and breast cancer genesis and progression...

Fructose' is metabolized in Aerobacter aerogenes primarily through the pathway: fructose -fructose-1-P -. fructose-1,6-P. Previous evidence for this pathway was the detection of an inducible fructose-i-P kinase2, I and the demonstration that a mutant lacking frustose-6-P kinase grew well on fructose but not on glucose, whereas a mutant lacking fructose 1,6-diphosphatase grew on glucose but not ...

The increase consumption of fructose in diet is associated with liver inflammation. As a specific fructan substrate, fructose may modify the gut microbiota which is involved in obesity-induced liver disease. Here, we aimed to assess whether fructose-induced liver damage was associated with a specific dysbiosis, especially in mice fed a high fat diet (HFD). To this end, four groups of mice were ...

the kinetics and mechanism of the reaction between benzaldehyde 1, malononitrile 2 and dimedone 3 in a mixture of ethanol and water as solvents in the presence of fructose as a biodegradable catalyst has been studied by the spectroscopic method (uv-vis spectrophotometry method). the influence of various parameters (temperature, solvent and concentration) was studied on the reaction by means of ...

Source/description: Fructose-1, 6-bisphosphate aldolase is a glycolytic enzyme which plays a critical role in the reversible conversion of fructose-1, 6-bisphosphate to glyceraldehydes 3-phosphate and dihydroxyacetone phosphate. It is reported that in vertebrates fructose-1, 6-bisphosphate aldolase has three isozymes: aldolase A, fructose-bisphosphate (ALDOA); aldolase B, fructose-bisphosphate ...

Fructose is a simple monosaccharide which is found in many plant foods. It is also used as a sweetening additive in the form of fructose corn syrup, a mixture of glucose and fructose. Its consumption is, in general, rising among the population. Setting aside the condition of hereditary fructose intolerance (which is relatively rare), it is possible for dietary intake of fructose to overload the...

A sensitive new method in which D-[U-14C]fructose-1-phosphate is used for fructose-bisphosphate aldolase (EC 2.1.2.13) assay is described. The radioactive fructose-1-phosphate compound was prepared from [U-14C]fructose by use of partly purified fructokinase (EC 2.7.1.4). With this method we measured normal values for aldolase in human liver (2.4-10.0 nmol/min per mg of protein), kidney (3.6-3.8...
