Intraerythrocytic Plasmodium falciparum expresses a high affinity facilitative hexose transporter. (1/840)

Asexual stages of Plasmodium falciparum cause severe malaria and are dependent upon host glucose for energy. We have identified a glucose transporter of P. falciparum (PfHT1) and studied its function and expression during parasite development in vitro. PfHT1 is a saturable, sodium-independent, and stereospecific transporter, which is inhibited by cytochalasin B, and has a relatively high affinity for glucose (Km = 0.48 mM) when expressed in Xenopus laevis oocytes. Competition experiments with glucose analogues show that hydroxyl groups at positions C-3 and C-4 are important for ligand binding. mRNA levels for PfHT1, assessed by the quantitative technique of tandem competitive polymerase chain reaction, are highest during the small ring stages of infection and lowest in gametocytes. Confocal immunofluorescence microscopy localizes PfHT1 to the region of the parasite plasma membrane and not to host structures. These findings have implications for development of new drug targets in malaria as well as for understanding of the pathophysiology of severe infection. When hypoglycemia complicates malaria, modeling studies suggest that the high affinity of PfHT1 is likely to increase the relative proportion of glucose taken up by parasites and thereby worsen the clinical condition.  (+info)

Effect of dietary taurine supplementation on GSH and NAD(P)-redox status, lipid peroxidation, and energy metabolism in diabetic precataractous lens. (2/840)

PURPOSE: To evaluate changes in glutathione and NAD(P)-redox status, taurine and malondialdehyde (MDA) levels, glucose utilization, and energy metabolism in diabetic precataractous lenses and to assess whether these changes can be prevented with dietary taurine supplementation. METHODS: The experimental groups included control and streptozotocin-diabetic rats with a 3-week duration of diabetes fed unsupplemented or taurine (1% or 5%)-supplemented diets. The levels of glucose, sorbitol, fructose, myo-inositol, oxidized glutathione (GSSG), glycolytic intermediates, malate, alpha-glycerophosphate, and adenine nucleotides were assayed in individual lenses spectrofluorometrically by enzymatic methods, reduced glutathione (GSH) spectrofluorometrically with O-phthaldialdehyde, MDA colorimetrically with N-methyl-2-phenylindole, and taurine by high-performance liquid chromatography. Free cytosolic NAD+/NADH and NADP+/NADPH ratios were calculated from the lactate dehydrogenase and malic enzyme systems. RESULTS: Sorbitol pathway metabolites and MDA were increased, and GSH and taurine levels were reduced in diabetic rats versus controls. The profile of glycolytic intermediates (an increase in glucose 6-phosphate, no change in fructose 6-phosphate and fructose 1,6-diphosphate, an increase in dihydroxyacetone phosphate, a decrease in 3-phosphoglycerate, phosphoenolpyruvate, and pyruvate, and no change in lactate), and a 9.2-fold increase in alpha-glycerophosphate suggest diabetes-induced inhibition of glycolysis. Free cytosolic NAD+/NADH ratios, ATP levels, ATP/ADP, and adenylate charge were reduced, whereas free cytosolic NADP+/NADPH ratios were elevated. Lens taurine levels in diabetic rats were not affected by supplementation with 1% taurine. With 5% taurine supplementation, they were increased approximately 2.2-fold higher than those in untreated diabetics but remained 3.4-fold lower than in controls. Lens GSH levels were similar in diabetic rats fed unsupplemented and 5% taurine-supplemented diets, whereas GSSG and MDA levels and GSSG/GSH ratios were reduced by 5% taurine supplementation. The decrease in free cytosolic NAD+/NADH, ATP/ADP, and adenylate energy charge were ameliorated by 5% taurine supplementation, whereas accumulation of sorbitol pathway intermediates, depletion of myoinositol, inhibition of glycolysis, a decrease in ATP and total adenine nucleotide, and an increase in free cytosolic NADP+/NADPH were not prevented. CONCLUSIONS: Dietary taurine supplementation ameliorates MDA levels, GSSG/GSH, and NAD+/NADH and fails to prevent the osmotically mediated depletion of GSH and taurine and the decrease in glucose utilization and ATP levels in diabetic precataractous lens. Dietary taurine supplementation cannot be regarded as an alternative to aldose reductase inhibition in eliminating antioxidant and metabolic deficits contributing to diabetes-associated cataractogenesis.  (+info)

Polyol formation and NADPH-dependent reductases in dog retinal capillary pericytes and endothelial cells. (3/840)

PURPOSE: Dogs fed a diet containing 30% galactose experience retinal vascular changes similar to those in human diabetic retinopathy, with selective pericyte loss as an initial lesion. In the present study the relationship among reduced nicotinamide adenine dinucleotide phosphate (NADPH)-dependent reductases, polyol formation, and flux through the polyol pathway in cultured dog retinal capillary cells were investigated. METHODS: Pericytes and endothelial cells were cultured from retina of beagle dogs. NADPH-dependent reductases were characterized by chromatofocusing after gel filtration. Sugars in cultured cells were analyzed by gas chromatography, and flux through the polyol pathway was investigated by 19F nuclear magnetic resonance (NMR) with 3-fluoro-3-deoxy-D-glucose (3FG) as a substrate. The presence of aldose reductase and sorbitol dehydrogenase in these cells was examined by northern blot analysis. RESULTS: Two distinct peaks corresponding to aldose reductase and aldehyde reductase, the latter being dominant, were observed in pericytes by chromatofocusing. Culture in medium containing either 10 mM D-galactose or 30 mM D-glucose resulted in the accumulation of sugar alcohol in pericytes that was markedly reduced by aldose reductase inhibitors. 19F NMR spectra obtained from pericytes cultured for 5 days in medium containing 2 mM 3FG displayed the marked accumulation of 3-fluoro-deoxysorbitol but not 3-fluoro-deoxyfructose. No 3FG metabolism was observed in similarly cultured endothelial cells. With northern blot analysis, aldose reductase was detected in pericytes but not in endothelial cells. Sorbitol dehydrogenase was below the detectable limit in pericytes and endothelial cells. CONCLUSIONS: Aldose, aldehyde, and glyceraldehyde reductases are present in dog retinal capillary pericytes, with aldehyde reductase being the major reductase present. Polyol accumulation easily occurs in pericytes but not in endothelial cells.  (+info)

Carbon assimilation by Claviceps purpurea growing as a parasite. (4/840)

Carbon assimilation by Claviceps purpurea, growing as a parasite on cereals, has been investigated by supplying the host plant with 14CO2 in a closed system. The presence of the pathogen induced the plant to exude photosynthate which contained high levels of sucrose. During the period of 14CO2 supply, 14C was incorporated into the sucrose and so the path of carbon into the parasite could be traced. Hexoses, derived by the action of the fungal sucrase on sucrose, were assimilated by the pathogen and largely converted into polyols - mainly mannitol and, to a lesser extent, trehalose. The rate of carbohydrate metabolism decreased with maturation of the ergot, and also showed qualitative differences between the basal and apical regions of the ergot which were probably a function of nutrient supply.  (+info)

Involvement of the Escherichia coli phosphoenolpyruvate-dependent phosphotransferase system in regulation of transcription of catabolic genes. (5/840)

Synthesis of catabolite-sensitive enzymes is repressed in mutants defective in the general proteins (enzyme I and HPr) of the Escherichia coli phosphoenolpyruvate-dependent phosphotransferase system (ptsI and ptsH mutations). To elucidate the mechanism of this phenomenon we constructed isogenic strains carrying pts mutations as well as different lesions of regulation of the lac operon or mutations affecting adenylate cyclase activity (cya mutation) and synthesis of cyclic AMP-receptor protein (crp mutation) Measurements of the differential rate of beta-galactosidase synthesis in these strains showed that the repressive effect of pts mutations was revealed in lac+, lacI, lacOc and cya bacteria, but it was lost in lacP and crp strains. It was concluded that mutational damage to the general components of the phosphoenolpyruvate-dependent phosphotransferase system diminishes activity of the lac promoter. The results obtained led to the conclusion that pts gene products (apparently phospho approximately HPr) are necessary for the initiation of transcription of catabolite-sensitive operons in E. coli.  (+info)

Sugars and sugar derivatives which inhibit the short-circuit current of the everted small intestine of the rat. (6/840)

1. The short-circuit current of everted rat intestine supported on a perforated cannula proved to be stable for up to 3 hr and has been used to study competition between transportable and non-transportable sugars. 2. 4,6-O-Ethylidene-alpha-D-glucopyranose (ethylidene glucose) and 4,6-O-benzylidene-e alpha-D-glucopyranos (benzylinene glucose), two nontransportable inhibitors of the hexose transfer system in human erythrocytes, were found to reduce the short-circuit current generated by transportable sugars such as galactose or 3-O-methyl glucose. 3. These compounds were also found to reduce the basal short-circuit current established by the everted intestine in a sugar-free Krebs solution. Both types of inhibition approached saturation at the higher concentrations used. 4. Similar inhibitory properties were shown by mannose, a non-actively accumulated monosaccharide, and by the beta-disaccharides lactose and cellobiose. 5. It is suggested that this common pattern of behaviour is due to the ability of these compounds to react with the sites for active hexose transfer but without translocation by the system. The significance of the inhibition of the basal short-circuit current is briefly discussed in this context.  (+info)

Structure of the O-specific polysaccharide of a serologically separate strain Proteus penneri 2 from a new proposed serogroup O66. (7/840)

O-specific polysaccharide chain of Proteus penneri strain 2 lipopolysaccharide was studied by full and partial acid hydrolysis, Smith degradation, methylation analysis, and NMR spectroscopy, including two-dimensional rotating-frame NOE spectroscopy (ROESY) and 1H,13C heteronuclear multiple-quantum coherence (HMQC) experiments. Together with D-glucose and 2-acetamido-2-deoxy-D-glucose, the polysaccharide was found to contain two rarely occurring sugars, 6-deoxy-L-talose (L-6dTal) and 2,3-diacetamido-2,3,6-trideoxy-L-mannose (L-RhaNAc3NAc), and the following structure of a non-stoichiometrically O-acetylated tetrasaccharide repeating unit was established: [equation: see text] The O-specific polysaccharide studied has a unique composition and structure and, accordingly, P. penneri 2 is serologically separate among Proteus strains. Therefore, we propose for P. penneri 2 a new Proteus O-serogroup O66 where this strain is at present the single representative.  (+info)

Structure of the glucan-binding sugar chain of Tip1p, a cell wall protein of Saccharomyces cerevisiae. (8/840)

Tip1p is one of the major cell wall mannoproteins of Saccharomyces cerevisiae and is presumed to be synthesized as a glycosylphosphatidylinositol (GPI)-anchored form. We purified Tip1p from a glucanase extract of yeast cell walls and analyzed the sugar chain involved in the cell wall linkage. One mol of glucanase-extracted Tip1p contained 7.5 mol of glucose derived from glucan and 1 mol of ethanolamine, a component of the GPI anchor. One mol of the C-terminal peptide of Tip1p digested with Achromobacter protease I also contained 7.9 mol of glucose and 1 mol of ethanolamine. On the other hand, Tip1p contained no glucosamine, which is a component of the GPI anchor. The glucan-binding sugar chain of Tip1p was released by hydrazinolysis and isolated. This sugar chain contained ethanolamine with a free amino group and a glucose reducing end, but no mannose reducing end. Phosphodiesterase treatment eliminated the free amino group from this sugar chain, suggesting that a phosphodiester bond exists between the ethanolamine and the glucan remnant. These results indicate (1) the glucan-binding sugar chain of Tip1p is a GPI derivative, and (2) the GPI anchor is cleaved at the glycosyl moiety, and the resultant mannose reducing end is probably used to link Tip1p to cell wall glucan.  (+info)

Use of [18F]FDG-PET in clinical breast cancer (BC) imaging is limited mainly due to insufficient expression levels of GLUT1 in up to 50% of all patients. Fructose-specific facilitative hexose transporter GLUT5 represents an alternative biomarker for PET imaging of hexose metabolism in BC. The goal of the present study was to compare uptake characteristics of selected hexose-based PET radiotracers in murine BC model EMT6. Uptake of 1-deoxy-1-[18F]fluoro-D-fructose (1-[18F]FDF), 6-deoxy-6-[18F]fluoro-D-fructose (6-[18F]FDF), 1-deoxy-1-[18F]fluoro-2,5-anhydro-mannitol (1-[18F]FDAM), 2-deoxy-2-[18F]fluoro-D-glucose (2-[18F]FDG) and 6-deoxy-6-[18F]fluoro-D-glucose (6-[18F]FDG) was studied in EMT6 cells, tumors and muscle and correlated to GLUT1 and GLUT5 expression levels ...

Major phosphoglucomutase isozyme that catalyzes the reversible interconversion of glucose 1-phosphate and glucose 6-phosphate (PubMed:5784209). Constitutes about 80-90% of the phosphoglucomutase activity in the cell (PubMed:14264884, PubMed:5231755). Key enzyme in hexose metabolism. The forward reaction is an essential step in the energy metabolism of galactose since the product of the galactose pathway enzymes in yeast is glucose 1-phosphate. The reverse reaction is an essential step for biosynthesis when carbon sources other than galactose are the energy source because glucose 1-phosphate is the starting point for the synthesis of UDP-glucose, which acts as a precursor for the synthesis of oligosaccharides and trehalose (PubMed:14264884).
D-glucose regulates maintenance and function of pancreatic beta-cells. Several studies have shown that IRS-2, but not IRS-1, is necessary to maintain and sufficient to expand functional beta-cell mass. We therefore analyzed the expression of IRS-2 and IRS-1 in beta-cells after culture in the presence of various concentrations of D-glucose and other metabolisable or non-metabolisable hexoses. D-glucose increased Irs-2 transcription and IRS-2 accumulation in a dose-dependent manner (1.6 to 25 mmol/l), with a 3-fold increased plateau after 10 h. In contrast, the expression of IRS-1 remained unaffected. D-glucose also induced phosphorylation of IRS-2 while non-metabolisable hexoses did neither affect expression nor phosphorylation. D-glucose-mediated elevation and phosphorylation of IRS-2 were independent of autocrine insulin action although insulin itself could transiently and slightly enhance IRS-2 expression. ...

Central carbon metabolism.Our data show that a large proportion of differentially expressed transcripts are related to core metabolic activities of the fermenting yeasts (Tables 1 and 2 and Fig. 4). Several enzymes involved in hexose metabolism, glycolysis, trehalose metabolism, and redox balance are differentially expressed between strains at various stages of fermentation. The analysis of the gene expression levels within the framework of enzyme-enzyme and enzyme-metabolite interaction graphs (using the reporter metabolite approach) helped to pinpoint areas of metabolism that could speculatively be related to strain-strain or time point variation.. Trehalose, glucose-6-phosphate, glucose, UDP-glucose, and fructose-6-phosphate scored high on the multiple analyses across time points during fermentation (Table 5). Indeed, these metabolites did show marked differences in concentration between time points (Fig. 5). Trehalose was also a prominent interstrain reporter for days 2 and 5 (Table 4), and ...

Research:. Genetic engineering provides an opportunity to improve the quality of plant foods by enhancing metabolic flux towards nutritionally-important compounds such as protein, oil, carotenoids, sterols and tocopherols. While efforts to increase levels of these compounds have been moderately successful, the ability to make nutritionally-significant changes often is limited by the availability of central metabolic precursors feeding into nutrient biosynthetic pathways. Enhancing precursor availability requires an understanding of the regulatory mechanisms controlling flux through central metabolic pathways. One of these central pathways, glycolysis, is a series of ten reactions that serves to catabolize hexose sugars to pyruvate. This pathway has a well-defined role to produce pyruvate for mitochondrial respiration and ATP generation, and in tissues with high biosynthetic activity (such as developing seeds), glycolysis generates 3-carbon precursors for amino acid, fatty acid, carotenoid and ...

CNTF treatment dose-dependently prevented NCV slowing in galactose-fed rats, a model of elevated hexose sugar metabolism by aldose reductase, and was without effect in control rats. We have previously shown that galactose intoxication markedly reduces nerve CNTF and that this depletion can be prevented by aldose reductase inhibition (13,14). As aldose reductase inhibitors also prevent NCV slowing in galactose-fed rats (14), it seems reasonable to suggest that nerve CNTF depletion is an intermediary in the causative sequence that leads from increased hexose sugar metabolism by aldose reductase in Schwann cells to NCV slowing. Providing exogenous CNTF may replace the deficient production of this factor by metabolically stressed Schwann cells, although the site of action of exogenous CNTF is not yet known and further studies are required to establish how CNTF maintains NCV.. Exogenous administration of CNTF also had a significant impact on nerve function in rats with already established STZ-induced ...
This dissertation focuses on the synthesis of dauer pheromone analogs for biological evaluation, the development of visible light promoted O-glycosylation methods and the development of an Ir(ppy)3 catalyzed C-H hydroxylation method. Chapter 1 describes the synthesis of dauer pheromone analogs. C.elegans is a small nematode that enters a dauer stage when encountering unfavorable environmental conditions. The dauer stage is initiated by the nematodes chemosensation of the dauer pheromone caused by the down regulation biochemical pathways TGF-â and IGF-1. These biochemical pathways are also seen in Homo Sapiens and play a role in a number of biological processes. Understanding how these pathways work in C.elegans can give us a better understanding of how they function in humans. In order to see the effect structure has on binding to the GCPRs that initiate dauer formation a series of dauer pheromone analogs differing in chain length and degree of unsaturation were synthesized. These analogous were then
The results of this study are consistent with our prediction that village weavers have a preference for hexose over sucrose sugar when offered solutions as dilute as those found in plants adapted for pollination by these birds (Fig. 1). A preference for hexose sugars is consistent with most of the previous studies on occasional nectarivores, except that tests on most of these species were conducted with high or intermediate concentration solutions, and most did not use equicaloric solutions (Martínez del Rio et al., 1989; Malcarney et al., 1994; Franke et al., 1997; Lane, 1997). At high concentrations (20% and 25% SE) village weavers showed no sugar preference (Fig. 1). At 15% [which is at the lower end of the range for nectar concentration in specialist-pollinated flowers (Johnson and Nicolson, 2008), and at low concentrations of 5% and 10% [typical of plants pollinated by generalist avian nectarivores (Johnson and Nicolson, 2008)], village weavers preferred hexose nectar solutions (Fig. 1). ...
is a metabolic pathway where each glucose molecule is broken down into two molecules of pyruvate. It occours in the cytoplasm of all living cells and is common to anaerobic and aerobic respiration.. Stage 1 Phosphorylation- one ATP molecule is hydrolysed and the phosphate group is released and attaches to the glucose molecule at carbon 6. This is then changed to fructose 6 phosphate and another ATP is hydrolysed and becomes fructose 1,6, bisphosphate. This activates the hexose sugar and prevents it from leaving the cell. Note: (2 molecules of ATP for each molecule) Stage 2- Splitting of hexose 1,6, bisphosphate into 2 triose phosphate Stage 3- Oxidation of triose phosphate- anaerobic but involves oxidation. Two hydrogen atoms are removed from triose phosphate (with dehydrogenase enzymes) These are aided but NAD which becomes reduced. Two molecules of NAD are reduced per glucose and also at this stage 2 molecules of ATP are formed (substrate level phosphorylation) Stage 4- Conversion of triose ...

This apparently simple change leads to the drastically different chemistry of the two hexoses, as it does the remaining six hexoses. ...

Looking for online definition of renal glycosuria in the Medical Dictionary? renal glycosuria explanation free. What is renal glycosuria? Meaning of renal glycosuria medical term. What does renal glycosuria mean?
Renal glycosuria, also known as renal glucosuria, is a rare condition in which the simple sugar (glucose) is excreted in the urine despite normal or low blood glucose levels. With normal kidney (renal) function, glucose is excreted in the urine only when there are abnormally elevated levels of glucose in the blood. However, in those with renal glycosuria, glucose is abnormally elevated in the urine due to improper functioning of the renal tubules, which are primary components of nephrons, the filtering units of the kidneys. In most affected individuals, the condition causes no apparent symptoms (asymptomatic) or serious effects. When renal glycosuria occurs as an isolated finding with otherwise normal kidney function, the condition is thought to be inherited as an autosomal recessive trait[citation needed]. It is associated with SLC5A2, coding the sodium-glucose cotransporter 2. A doctor normally can diagnose renal glycosuria when a routine urine test (Urinalysis) detects glucose in the urine, ...

A ketohexose is a ketone-containing hexose (a six-carbon monosaccharide). The most common ketohexoses, each of which represents a pair of enantiomers (D- and L-isomers), include psicose, fructose, sorbose, and tagatose. Ketohexose is stable over a wide pH range, and with a primary pKa of 10.28, will only deprotonate at high pH, so is marginally less stable than aldohexose in solution.

Glucophage 1000mg Tablets About Metformin Biguanide derivative, Oral anti-diabetic. Mechanism of Action of Metformin It is a biguanide which exerts antidiabetic action. The drug suppresses gluconeogenesis in liver and thus suppresses hepatic glucose output. It enhance insulin mediated glucose disposal in muscle and adipose tissue. It enhance GLUT1 (glucose transporter-1) transport from intracellular site to plasma membrane. It also interferes with respiratory chain in mitochondria and promotes peripheral glucose utilization by increasing anaerobic glycolysis. It inhibits intestinal absorption of glucose, other hexose sugars, amino acids and vitamin B12. It also improves lipid profile in type-2 diabetics. Indications for Metformin Non-insulin dependent diabetes mellitus (as adjunct to diet and exercise). Typical Dosage for Metformin Adults: Initial dose: 250mg twice or thrice daily with meals. Increase gradually at 2 week intervals, if required to a maximum of 3g daily. Children: Not applicable.
The Haemophilus influenzae HMW1 adhesin is a high-molecular weight protein that is secreted by the bacterial two-partner secretion pathway and mediates adherence to respiratory epithelium, an essential early step in the pathogenesis of H. influenzae disease. In recent work, we discovered that HMW1 is a glycoprotein and undergoes N-linked glycosylation at multiple asparagine residues with simple hexose units rather than N-acetylated hexose units, revealing an unusual N-glycosidic linkage and suggesting a new glycosyltransferase activity. Glycosylation protects HMW1 against premature degradation during the process of secretion and facilitates HMW1 tethering to the bacterial surface, a prerequisite for HMW1-mediated adherence. In the current study, we establish that the enzyme responsible for glycosylation of HMW1 is a protein called HMW1C, which is encoded by the hmw1 gene cluster and shares homology with a group of bacterial proteins that are generally associated with two-partner secretion ...

This work investigates the effect of plant species (Eucalyptus camaldulensis vs. Arundo donax) on carbon (C) turnover during wastewater application to the land. The study was carried out in 40-liter pots under field conditions and plant species were treated either with pre-treated municipal wastewater or freshwater. Plant species had a strong effect on soil organic matter with pots planted with E. camaldulensis showing greater values than pots planted with A. donax. In accordance, greater respiration rates were measured in E. camaldulensis pots compared to those planted with A. donax. The respiration rate followed a decreasing trend with the progress of the season for both species. These findings suggest differences in soil microbial community composition and/or activity in the rhizosphere of plant species. Minor effects of plant species or effluent were observed in dissolved organic carbon, protein, and hexoses content. In conclusion, the results of the present study reveal an important role of plant
The PBT Assessment for Sorbitan, (Z)-9-octadecenoate (2:3) (CAS No. 8007-43-0) is based on the criteria set out in the Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment (ECHA, 2012). Persistence The read-across substancesanhydro-D-glucitol trioleate (CAS No. 26266-58-0)is readily biodegradable according to OECD 301 B (84.5% (CO2 evolution) after 28 days). Thus, Sorbitan, (Z)-9-octadecenoate (2:3) (CAS No. 8007-43-0) does not meet the screening criterion for persistency and it is not considered to be P or vP. Bioaccumulation Due to the low water solubility, rapid environmental biodegradation and metabolism via enzymatic hydrolysis of the Sorbitan esters category members, a relevant uptake and bioaccumulation in aquatic organisms is not expected. Enzymatic breakdown will initially lead to the free fatty acid and D-glucitol. From literature it is well known, that these hydrolysis products will be metabolised and excreted in fish effectively ...

S. cerevisiae has membrane proteins that act as glucose receptors. Glucose binds to these receptors and generates an intracellular signal. In the Rgt2/Snf3 pathway, these two proteins act as glucose receptors. The Rgt2 and Snf3 proteins resemble hexose transporters in structure but have long cytoplasmic tails that are required for signal transduction [7]. Glucose binding to these transmembrane proteins initiates signals that activate a pathway that allows hexose transporter gene expression by repressing Rgt1 function [8].. An additional pathway that involves transcriptional changes in response to glucose is the stimulation of adenylyl cyclase and the increase in intracellular cyclic AMP. This pathway includes a G-protein coupled receptor (Gpr1) and two G proteins Gpa1 and 2, necessary for the glucose-specific increase in cAMP [9,10]. Finally, glucose activation of adenylyl cyclase leads to activation of the cAMP-dependent protein kinase A (PKA). Upon activation of PKA by cAMP the Rap1 ...
D-glucopyranoside, also known as hexose or D-galactose, is a member of the class of compounds known as hexoses. Hexoses are monosaccharides in which the sugar unit is a is a six-carbon containing moeity. D-glucopyranoside is soluble (in water) and a very weakly acidic compound (based on its pKa). D-glucopyranoside can be found in a number of food items such as marzipan, olive, channel catfish, and rubus (blackberry, raspberry), which makes D-glucopyranoside a potential biomarker for the consumption of these food products. D-glucopyranoside exists in all living organisms, ranging from bacteria to humans. The name was originally given to plant products of this nature, in which the other part of the molecule was, in the greater number of cases, an aromatic aldehydic or phenolic compound (exceptions are sinigrin and jalapin or scammonin). It has now been extended to include synthetic ethers, such as those obtained by acting on alcoholic glucose solutions with hydrochloric acid, and also the ...

N2 - Background and Aims Border cells are released from the root tips of many plant species, and can remain viable in the rhizosphere for 1 week. Whether border cells are capable of controlled glucose exchange with their environment was investigated.Methods Border cells were removed from Zea mays L. root tips, and immersed in C-14-labelled D-glucose. In one experiment, the hexose transport inhibitor, phlorizin, was used to investigate active glucose uptake from a range of glucose concentrations. In another experiment, glucose efflux from border cells was monitored over time.Key Results Glucose uptake by the border cells increased with increasing glucose concentration from 0.2 to 20 mM. At 0.2 mM glucose, uptake was mainly active, as evidenced by the approx. 60% inhibition with phlorizin. At 2 and 20 mm ...
