Fructose-1,6-bisphosphate (FBP) disodium salt, with CAS number 84364-89-6, is a phosphorylated sugar derivative and a key intermediate in the glycolytic and gluconeogenic metabolic pathways. It is a high-energy compound that plays a central role in cellular energy production and regulation. Its primary application is in life science research as a biochemical reagent. It is used to study metabolic pathways, enzyme kinetics (e.g., aldolase activity), and cellular energetics. In the pharmaceutical field, it has been investigated for its potential cytoprotective effects, particularly in ischemia-reperfusion injury models for organs like the heart and liver, due to its role in supporting anaerobic glycolysis and stabilizing cell membranes. Beyond research, fructose-1,6-bisphosphate salts can function as buffering agents and energy sources in certain specialized cell culture media or diagnostic reagent formulations. It is typically handled as a stable, hygroscopic solid and should be stored under appropriate conditions to maintain its biochemical activity.
