WebAug 20, 2024 · - The first step of the pentose phosphate pathway is the conversion of glucose-6-phosphate to 6-phosphogluconolactone and generation of NADPH from NADP+. This oxidation-reduction coupled reaction is catalyzed by the enzyme glucose-6-phosphate dehydrogenase (G6PD). G6PD is a rate-limiting enzyme of the pentose phosphate pathway. WebGlucose-6-phosphate dehydrogenase (G6PD) is a cytoplasmic enzyme that is essential for an erythrocyte’s capacity to withstand oxidant stress. G6PD activity is significantly decreased in the genetically inherited disorder, G6PD deficiency. It is typically measured in RBCs during workup for an unknown cause of hemolytic anemia or neonatal jaundice.
