| deficiency, glucose-6-phosphate dehydrogenase | Deficiency of G6PD is the commonest disease-causing enzyme defect in humans affecting an estimated 400 million people. The G6PD gene is on the X chromosome. Males with the enzyme deficiency develop anaemia due to breakup of their red blood cells when they are exposed to oxidant drugs such as the antimalarial primaquine, the sulfonamide antibiotics or sulfones, naphthalene moth balls, or fava beans.

| dihydroxyacetone phosphate | This is an intermediate molecule involved in the fourth step of glycolysis. Dihydroxyacetonephosphate is created from fructose 1,6-bisphosphate. In step 5, it is converted into its positional isomer, glyceraldehyde3-phosphate, with the aid of triose-phosphate isomerase. (09 Oct 1997) |
