D-Fructose 6-phosphate dipotassium is an endogenous metabolite found in saliva that influences cell growth and autophagy. It is produced by the hydrolysis of Fructose-1,6-bisphosphatase (FBPase). Under the action of phosphoglucose isomerase, D-Fructose 6-phosphate dipotassium can be converted into D-glucose 6-phosphate (HY-112537). This compound acts as a sugar intermediate in both the glycolysis and pentose phosphate pathways. D-Fructose 6-phosphate dipotassium is used in research related to Lewy body dementia.
