 glucose 6-phosphate (also known as robison ester) is glucose sugar phosphorylated on carbon 6. this compound is very common in cells as the vast majority of glucose entering a cell will become phosphorylated in this way. because of its prominent position in cellular chemistry, glucose 6-phosphate has many possible fates within the cell. it lies at the start of two major metabolic pathways, glycolysis and pentose phosphate pathway. in addition to these metabolic pathways, glucose 6-phosphate may also be converted to glycogen or starch for storage. this storage is in the liver and muscles in the form of glycogen for most multicellular animals, and in intracellular starch or glycogen granules for most other organisms. ==production of glucose 6-phosphate== ===from glucose=== within a cell, glucose 6-phosphate is produced by phosphorylation of glucose on the sixth carbon. this is catalyzed by the enzyme hexokinase in most cells, and, in higher animals, glucokinase in certain cells, most notably liver cells. one molecule of atp is consumed in this reaction.     {{kegg reaction|r01786
