D-myo-Inositol 1,4-bisphosphate
D-myo-Inositol 1,4-bisphosphate belongs to the class of organic compounds known as inositol phosphates. Inositol phosphates are compounds containing a phosphate group attached to an inositol (or cyclohexanehexol) moiety. D-myo-Inositol 1,4-bisphosphate is an extremely weak basic (essentially neutral) compound (based on its pKa). D-myo-Inositol 1,4-bisphosphate is a substrate for several proteins including inositol polyphosphate 1-phosphatase, phosphatidylinositol 4,5-bisphosphate 5-phosphatase A, skeletal muscle and kidney enriched inositol phosphatase, and type I inositol-1,4,5-trisphosphate 5-phosphatase. 1D-Myo-inositol 1,4-bisphosphate is a substrate for Inositol polyphosphate 1-phosphatase, Phosphatidylinositol 4,5-bisphosphate 5-phosphatase A, Skeletal muscle and kidney enriched inositol phosphatase and Type I inositol-1,4,5-trisphosphate 5-phosphatase.

alpha-D-Glucose 1,6-bisphosphate
Glucose 1,6-diphosphate (G-1,6-P2) is considered to be a major regulator of carbohydrate metabolism. It has been demonstrated that G-1,6-P2 is a potent activator (deinhibitor) of skeletal muscle phosphofructokinase (PFK) and phosphoglucomutase, while being an inhibitor of hexokinase (see Ref. 2). In addition, G-1,6-P2 has been shown to inhibit 6-phosphogluconate dehydrogenase in various rat tissues and fructose 1,6-bisphosphatase in bovine liver. Various factors and conditions affect the tissue content of G-1,6-P2. Specifically, anoxia induces a rapid fall in the content of G-l,6-P2 in the brain. Glucose 1,6-diphosphate has been recognized as a regulatory signal implicated in the control of metabolism, oxygen affinity of red cells, and other cellular functions. The levels of G 1,6-P2 are reduced in the liver and in the muscle of rats with experimentally induced diabetes. In muscle of genetically dystrophic mice, a decrease in the levels of G 1,6-P2 has been found, probably resulting from enhancement of glucose 1,6-P2 phosphatase activity. G 1,6-P2 is an inhibitor of hexokinase and its level is increased significantly after 5 min of exercise (~25\\%) and then decreased continuously. G 1,6-P2 is a potent allosteric activator of phosphofructokinase, and is markedly decreased in muscles of patients with glycogenosis type VII (muscle phosphofructokinase deficiency) and type V (muscle phosphorylase deficiency). Chronic alcohol intake produces an increase in the concentration of G 1,6-P2 in human muscle before the first sign of myopathy appears. When myopathy is present the level decreases to be similar to healthy humans. These changes could contribute to the decline in skeletal muscle performance (PMID:1449560, 2018547, 2003594, 3407759).

D-Fructose 2,6-bisphosphate
D-Fructose 2,6-bisphosphate (CAS: 77164-51-3), also known as phosphofructokinase activator, belongs to the class of organic compounds known as pentose phosphates. These are carbohydrate derivatives containing a pentose substituted by one or more phosphate groups. D-Fructose 2,6-bisphosphate is a regulatory molecule controlling the activity of the enzyme phosphofructokinase-1 or PFK1 (in mammals). PFK1, in turn, is the key regulatory enzyme in the central metabolic pathway glycolysis. D-Fructose 2,6-bisphosphate has the effect of increasing the activity of PFK1, thus increasing the rate at which the principle food molecule glucose is broken down. At the same time, this regulatory molecule also inhibits the opposing enzyme (FBPase1) in the reverse pathway (gluconeogenesis) so that the synthesis of glucose is not taking place in the same cell where glucose is being broken down (which would be wasteful).

Fructose 1,6-bisphosphate
Fructose 1,6-bisphosphate is fructose sugar or fructosephosphate that has been phosphorylated on carbons 1 and 6. The beta-D-form of this compound is very common in cells. The vast majority of glucose and fructose entering a cell is converted to fructose 1,6-bisphosphate at some point. Fructose 1,6-bisphosphate is a key component in the glycolysis metabolic pathway and is produced by phosphorylation of fructose 6-phosphate The enzyme phosphofructokinase uses ATP to transfer a phosphate group to fructose 6-phosphate to form fructose 1, 6-bisphosphate fructose. The enzyme aldolase splits fructose 1,6-bisphosphate into two sugars that are isomers of each other. These two sugars are dihydroxyacetone phosphate and glyceraldehyde phosphate. Fructose 1,6-bisphosphate is an allosteric activator of pyruvate kinase. The hydrolysis of fructose 1,6-bisphosphate is catalized by Fructose-1,6-bisphosphatase (fru-1,6-P2ase, EC 3.1.3.11) to fructose 6-phosphate and inorganic phosphate and provides a mechanism to permit the reversal of the glycolysis reaction (catalyzed by 6-phosphofructo-1-kinase).(OMIM) [HMDB]. D-Fructose 1,6-bisphosphate is found in many foods, some of which are garden cress, cascade huckleberry, wild celery, and devilfish.
