G6PD converts G6P into 6-phosphoglucono-δ-lactone and is the rate-limiting enzyme of the pentose phosphate pathway. Thus, regulation of G6PD has downstream consequences for the activity of the rest of the pentose phosphate pathway. Glucose-6-phosphate dehydrogenase is stimulated by its substrate G6P.
Glucose-6-phosphate dehydrogenase (G6PD) is an enzyme in the pentose phosphate pathway (see image, also known as the HMP shunt pathway). G6PD converts glucose-6-phosphate into 6-phosphoglucono-δ-lactone and is the rate-limiting enzyme of this metabolic pathway that supplies reducing energy to cells by maintaining the level of the reduced form ...

The NADPH pathway (both 6PGD and G6PD reactions) is the only source of reductant to reduce glutathione in red blood cells. The role of erythrocytes as oxygen carriers puts them at risk of being damaged by oxidizing free radicals. The reduction of glutathione acts as an antioxidant and prevents damage from reactive oxygen species. [citation needed]
G6PD deficieny is much more common than favism, and equating the two is being needlessly alarmist. The Al-Ali article (HTML version) is only used as a specific example, not a authoritative reference. It describes a small study of over 757 Saudi men. Over 42% of them tested positive for G6PD deficiency, but none of them reported symptoms of favism.
