2-Deoxy-d-glucose is a glucose molecule which has the 2-hydroxyl group replaced by hydrogen, so that it cannot undergo further glycolysis. As such; it acts to competitively inhibit the production of glucose-6-phosphate from glucose at the phosphoglucoisomerase level (step 2 of glycolysis).
Upon reaching the plasmalemma, the vesicles fuse with the membrane, increasing the number of GLUT4 transporters expressed at the cell surface, and hence increasing glucose uptake. GLUT4 has a Km value for glucose of about 5 mM, which as stated above is the normal blood glucose level in healthy individuals.
2-deoxy-D-glucose, or 2DG. 2-Deoxyglucose was the first agent pursued as a possible CRM. [2] [4] [27] This compound inhibits glycolysis, and can mimic some of the physiological effects of CR, in particular increased insulin sensitivity, reduced glucose levels, reduced body temperature, and other biochemical changes.
Eating food for example leads to elevated blood sugar levels. In healthy people, these levels quickly return to normal via increased cellular glucose uptake which is primarily mediated by increase in blood insulin levels. [citation needed] Glucose tests can reveal temporary/long-term hyperglycemia or hypoglycemia. These conditions may not have ...
The uptake of [18 F]FDG by tissues is a marker for the tissue uptake of glucose, which in turn is closely correlated with certain types of tissue metabolism. After [ 18 F]FDG is injected into a patient, a PET scanner can form two-dimensional or three-dimensional images of the distribution of [ 18 F]FDG within the body.
d -Glucose + 2 [NAD] + + 2 [ADP] + 2 [P] i 2 × Pyruvate 2 × + 2 [NADH] + 2 H + + 2 [ATP] + 2 H 2 O Glycolysis pathway overview The use of symbols in this equation makes it appear unbalanced with respect to oxygen atoms, hydrogen atoms, and charges. Atom balance is maintained by the two phosphate (P i) groups: Each exists in the form of a hydrogen phosphate anion, dissociating to contribute ...

Coupled assay for hexokinase using glucose-6-phosphate dehydrogenase. Even when the enzyme reaction does not result in a change in the absorbance of light, it can still be possible to use a spectrophotometric assay for the enzyme by using a coupled assay. Here, the product of one reaction is used as the substrate of another, easily detectable ...
