What it does, reaction by reaction

1 reactions

Pentose Phosphate Pathway (Oxidative and Non-oxidative phases) Carbohydrate Metabolism · Cytosol

step 3 Irreversible

6-Phosphogluconate + NADP+ → ribulose-5-phosphate + CO2 + NADPH + H+

Converts 6-Phosphogluconate NADP+ into Ribulose-5-phosphate CO2 NADPH H+

› Notes

6-Phosphogluconate dehydrogenase requires NADP+ and a divalent cation such as Mg2+ or Mn2+. Oxidative decarboxylation yields the second NADPH; this is the second irreversible reaction of the oxidative phase.
