pyruvate ---> glucose ok so my professor gave us the task of synthesizing glucose from pyruvate and i'm stuck somewhere near the middle . showing all my work so far would clutter this thread quite a bit so i'll simplify. pyruvate -> oxaloacetate -> phosphoenolpyruvate -> 2-phosphoglycerate -> 3-phosphoglycerate -> 3-phosphoglyceroylphosphate -> STUCK HERE! i see i need to reduce 3-phosphoglyceroylphosphate then do keto-enol tautomerization in order for an aldol reaction to form fructose, but i cant figure out what to reduce it with! anyone know? my book doesn't seem to cover this step . thanks!
