Glucose-6-Phosphate Dehydrogenase Activity and Glutathione Stability in Fetal and Adult Bovine Erythrocytes

Previously, we found a substantially higher glucoses-phosphate dehydrogenase (G6PD) activity and a slightly higher 6-phosphogluconate dehydrogenase (6PGD) activity in bovine fetal erythrocytes than in bovine adult erythrocytes (Steensgaard 1968). Now, we have investigated whether these differences in dehydrogenase activities were followed by characteristic differences in glutathione (GSH) stability and glutathione concentration. The results are shown in Table 1, which also gives the results of the same investigations on normal and G6PD deficient human erythrocytes.
