Abstract Background Cell simulation which aims to predict the complex and dynamic behavior of living cells is becoming a valuable tool. In silico models of human red blood cell RBC metabolism have been developed by several laboratories. An RBC model using the E-Cell simulation system has been developed. This prototype model consists of three major metabolic pathways namely the glycolytic pathway the pentose phosphate pathway and the nucleotide metabolic pathway. Like the previous model by Joshi and Palsson it also models physical effects such as osmotic balance. This model was used here to reconstruct the pathology arising from hereditary glucose-6-phosphate dehydrogenase G6PD deficiency which is the most common deficiency in human RBC. Results Since the prototype model could not reproduce the state of G6PD deficiency the model was modified to include a pathway for de novo glutathione synthesis and a glutathione disulfide GSSG export system. The de novo glutathione GSH synthesis pathway
