Autoignition =Glucose 1-phosphate (also called cori ester) is a
glucose molecule with aphosphate group on the 1'-carbon.Reactions
Catabolic
In
glycogenolysis , it is the direct product of the reaction in whichglycogen phosphorylase cleaves off amolecule ofglucose from a greaterglycogen structure.To be utilized in cellular catabolism it must first be converted to
glucose 6-phosphate by theenzyme phosphoglucomutase . One reason that cells form glucose-1-phosphate instead of glucose during glycogen breakdown is that the very polar phosphorylated glucose cannot leave the cell membrane and so is marked for intracellular catabolism.Anabolic
In
glycogenesis , free glucose 1-phosphate can also react withUTP to formUDP-glucose , by using the enzymeUDP-glucose pyrophosphorylase . It can then return to the greater glycogen structure viaglycogen synthase .ee also
