Fructose 6-phosphate (also known as the Neuberg ester) is fructose sugar phosphorylated on carbon 6 (i.e., 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 this at some point. The name Neuberg ester comes from the German biochemist Carl Neuberg.

History[edit]

In 1918, Carl Neuberg found that the compound (only later identified as fructose 6-phosphate) could be produced by mild acid hydrolysis of "Harden-Young ester" (fructose 2,6-bisphosphate).[1]

Fructose 6-phosphate in glycolysis[edit]

Fructose 6-phosphate lies within the glycolysis metabolic pathway and is produced by isomerisation of glucose 6-phosphate. It is in turn further phosphorylated to fructose-1,6-bisphosphate.
