The model contains one compartment called C. There are four species named S1, S2, S3 and S4 and four parameters named k1, k2, k3 and p1. The model contains three reactions defined as:
Reaction | Rate |
S1 → S2 | k1 · S1 · C · time |
(2 * p1)S2 → S3 | k2 · S2 · C · time |
S3 → S4 | k3 · S3 · C · time |
where the symbol 'time' denotes the current simulation time.
The initial conditions are as follows:
Value | Units | |
Initial amount of S1 | 1.0 × 10−1 | mole |
Initial amount of S2 | 0 | mole |
Initial amount of S3 | 0 | mole |
Initial amount of S4 | 0 | mole |
Value of parameter k1 | 0.7 | second-2 |
Value of parameter k2 | 0.5 | second-2 |
Value of parameter k3 | 1 | second-2 |
Value of parameter p1 | 1 | dimensionless |
Volume of compartment C | 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.
