Glyceraldehyde-3-phosphate

 

Reaction 5: Oxidation/Phosphate Ester Synthesis

This reaction is first an oxidation involving the coenzyme NAD+. The aldehyde is oxidized to an acid as an intermediate through the conversion of NAD+ to NADH + H+. Then an inorganic phosphate is added in a phosphate esteer synthesis.

This and all remaining reactions occur twice for each glucose-6-phosphate (six carbons), since there are now two molecules of 3-carbons each.

This reaction is catalyzed by glyceraldehyde-3-phosphate.
