NameFructose 1,6-bisphosphate
SpeciesSaccharomyces cerevisiae
StrainBaker's yeast
DescriptionFructose 1,6-bisphosphate (also known as Harden-young ester) is a fructose sugar phosphorylated on carbons 1 and 6. The β-D-form of this compound is very common in cells. The vast majority of glucose and fructose entering a cell will become converted to fructose 1,6-biphosphate at some point. Fructose 1,6-bisphosphate lies within the glycolysis metabolic pathway and is produced by phosphorylation of fructose 6-phosphate. It is, in turn, broken down into two compounds: glyceraldehyde 3-phosphate and dihydroxyacetone phosphate. It is an allosteric activator of pyruvate kinase. [Wikipedia]
