Return to overview

Upon being transported out of the cell, the eicosanoids accumulate in the interstitial fluid, which for simplicity is referred to as the extracellular compartment in the model. A decay constant was included for each extracellular metabolite to represent degradation. To describe the breaking down of metabolites an irreversible mass action rate law was used for reactions 43-64. The half life of each eicosanoid was initially assumed as 24 hours, but will be made metabolite specific when all of the values have been collected.
