Fructose 1,6-phosphate is fructose sugar phosphorylated on carbons 1 and 6 (ie. is a fructosephosphate). 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-phosphate at some point.

Fructose 1,6-phosphate in glycolysis

Fructose 1,6-phosphate 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 glycerone phosphate. It is allosteric activator of pyruvate kinase.
