The model contains one compartment called "compartment". There are two species named S1 and S2 and two parameters named k1 and k2. Both species S1 and S2 are labeled as an SBML boundary species. The model contains two reactions defined as:
Reaction | Rate |
S1 → S2 | k1 · S1 · compartment |
S2 → S1 | k2 · S2 · compartment |
The initial conditions are as follows:
Value | Units | |
Initial amount of S1 | 1.5 × 10−4 | mole |
Initial amount of S2 | 1.5 × 10−4 | mole |
Value of parameter k1 | 0.5 | second-1 |
Value of parameter k2 | 0.25 | second-1 |
Volume of compartment "compartment" | 1 | litre |
The species values are given as amounts of substance to make it easier to use the model in a discrete stochastic simulator, but (as per usual SBML principles) their symbols represent their values in concentration units where they appear in expressions.
Note: The test data for this model was generated from an analytical solution of the system of equations.
