α-D-Glucose-1-phosphate
Glucose 1-phosphate (also called cori ester) is a glucose molecule with a phosphate group on the 1-carbon. It can exist in either the α- or β-anomeric form. Glucose 1-phosphate belongs to the class of organic compounds known as monosaccharide phosphates. These are monosaccharides comprising a phosphated group linked to the carbohydrate unit. Glucose 1-phosphate is the direct product of the reaction in which glycogen phosphorylase cleaves off a molecule of glucose from a greater glycogen structure. It cannot travel down many metabolic pathways and must be interconverted by the enzyme phosphoglucomutase in order to become glucose 6-phosphate. Free glucose 1-phosphate can also react with UTP to form UDP-glucose. It can then return to the greater glycogen structure via glycogen synthase. *Found widely in both plants and animals. A precursor of starch in plants and of glycogen in animals. [CCD] Acquisition and generation of the data is financially supported in part by CREST/JST.
