=== Regulation of the PPP ===
The pentose phosphate pathway is regulated by negative feedback. NADPH allosterically inhibits ''glucose 6-phosphate dehydrogenase''. If the level of NADPH is high, ''glucose 6-phosphate dehydrogenase'' will be allosterically activated. If the level is low, the enzyme will be un-inhibited.
