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).
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.
Method of glucose uptake differs throughout tissues depending on two factors; the metabolic needs of the tissue and availability of glucose.The two ways in which glucose uptake can take place are facilitated diffusion (a passive process) and secondary active transport (an active process which on the ion-gradient which is established through the hydrolysis of ATP, known as primary active ...

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 ...

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 enzyme 2-deoxyglucose-6-phosphatase (EC 3.1.3.68) catalyzes the reaction 2-deoxy- D -glucose 6-phosphate + H 2 O ⇌ {\displaystyle \rightleftharpoons } 2-deoxy- D -glucose + phosphate This enzyme belongs to the family of hydrolases , specifically those acting on phosphoric monoester bonds.
