Fructose 6-phosphate (F6P) belongs to the class of organic compounds known as hexose phosphates. These are carbohydrate derivatives containing a hexose substituted by one or more phosphate groups. F6P is a derivative of fructose, which has been phosphorylated at the 6-hydroxy group. Fructose 6-phosphate is a fundamental metabolite and exists in all living species, ranging from bacteria to plants to humans. The great majority of glucose is converted to fructose 6-phosphate as part of the glycolytic metabolic pathway (glycolysis). Specifically, F6P is produce is produced by the isomerisation of glucose 6-phosphate via the enzyme phosphoglucose isomerase. F6P is in turn further phosphorylated to fructose-1,6-bisphosphate by the enzyme phosphofructokinase-1. Glycolysis is the metabolic pathway that converts glucose into pyruvic acid. The free energy released in this process is used to form ATP and reduced nicotinamide adenine dinucleotide (NADH). In addition to its key involvement in glycolysis, fructose 6-phosphate can also be biosynthesized from glucosamine 6-phosphate via the enzyme glucosamine-6-phosphate isomerase 1. In addition, fructose 6-phosphate and L-glutamine can be converted into glucosamine 6-phosphate and L-glutamic acid through the action of the enzyme glutamine--fructose-6-phosphate aminotransferase. An important intermediate in the Carbohydrates pathway. The interconversion of glucose-6-phosphate and fructose-6-phosphate, the second step of the Embden-Meyerhof glycolytic pathway, is catalyzed by the enzyme phosphoglucose isomerase (PGI). In gluconeogenesis, fructose-6-phosphate is the immediate precursor of glucose-6-phosphate (wikipedia) [HMDB] Acquisition and generation of the data is financially supported in part by CREST/JST.

Mannose 6-phosphate

C6H13O9P (260.0297178)


Mannose 6-phosphate, also known as alpha-D-mannose-6-p or man-6-p, belongs to the class of organic compounds known as hexose phosphates. These are carbohydrate derivatives containing a hexose substituted by one or more phosphate groups. Mannose 6-phosphate exists in all eukaryotes, ranging from yeast to humans. Within humans, mannose 6-phosphate participates in a number of enzymatic reactions. In particular, mannose 6-phosphate can be converted into fructose 6-phosphate through its interaction with the enzyme mannose-6-phosphate isomerase. In addition, mannose 6-phosphate can be biosynthesized from D-mannose through the action of the enzyme hexokinase-1. Mannose 6-phosphate is a potent competitive inhibitor of pinocytosis of human platelet beta-glucuronidase and it is a necessary component of the recognition marker on the enzyme for pinocytosis by human fibroblasts as well (PMID 908752). In humans, mannose 6-phosphate is involved in fructose intolerance, hereditary.
