2-DEOXY-D-GLUCOSE-6-PHOSPHATE SODIUM SA+

General description

2-Deoxy-d-glucose (2DG) 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). In most cells, glucose hexokinase phosphorylates 2-deoxyglucose, trapping the product 2-deoxyglucose-6-phosphate (2DG6P) intracellularly. 2DG & 2DG6P serve as good markers for tissue glucose uptake and hexokinase activity. For example, many cancers have elevated glucose uptake and hexokinase levels. 2DG6P undergoes only the first enzymatic reaction in the pentose phosphate pathway to generate 2-DG-6-phosphogluconolactone, which cannot be further metabolized.
