D-glucose, D-galactose and D-fructose are all. 1. Isomers 2. Epimers 3. Aldohexoses 4.Monosaccharides . View Solution Glucose does not give View Solution D−Fructose with dil.NaOHundergoes a reversible isomerisation and is converted to a mixure ofD−glucose,D−mannose andS−fructose. ...
The kinetics of glucose and galactose uptake have been extensively studied and reveal that below physiological temperatures, the Km and Vmax for efflux can up to 10-fold higher than for influx. In addition, the kinetic parameters for exchange transport (Km and Vmax) are both approximately 10-...
Recognition of both sugar epimers is accomplished principally by hydrogen bonding of Asp14 OD1 with the equatorial OH4 of D-glucose and OD2 with the axial OH4 of D-galactose. These results are reconciled with equilibrium and fast kinetics data, which indicate binding of both anomers of the ...
Interestingly, the glucose epimers psicose, altrose, mannose, and galactose do not induce TXNIP (data not shown), demonstrating that not all hexoses are capable of regulating MondoA function. We originally proposed that MondoA senses Glc-6-P (4) and our experiments here using the PGI-...
Methods have been developed for the enzymatic synthesis of α-glucose 1-thiophosphate, α-galactose 1-thiophosphate, glucose 6-thiophosphate, uridine-5′- O-(2-thiodiphosphoglucose), and uridine-5′- O-(2-thiodiphosphogalactose). The purified compounds were shown to be substrates for sucrose ...
Since D-glucose and D-mannose are C-2 epimers and in consequence their deoxygenation at C-2 would produce the same compound, the 2-DG should also be considered an analogue of D-mannose [1] (Figure 1). A significant number of halogen-substituted carbohydrates have been synthesized. Some of...
