Glucose-6-phosphate dehydrogenase (G6PD) is an enzyme that plays a crucial role in the pentose phosphate pathway (PPP), a metabolic pathway that generates NADPH and pentoses from glucose-6-phosphate. G6PD is the first enzyme in the PPP and is responsible for catalyzing the conversion of glucose-6-phosphate to 6-phosphogluconate, producing NADPH in the process.
**** patients who receive intravenous ascorbate must be prescreened for glucose 6 phosphate dehydrogenase deficiency.
G6PD expression is often elevated in various cancers and is generally linked to poorer prognosis.
