The model contains one compartment called "compartment". There are three species named S1, S2 and S3. The model contains two reactions defined as:
Reaction | Rate |
S1 → S2 | k · S1 · compartment, |
S2 → S3 | k · S2 · compartment, |
Reaction S1 → S2 defines one local parameter k. Reaction S2 → S3 also defines one (different) local parameter k. Both of these parameters have a scope local to the defining reaction.
The initial conditions are as follows:
Value | Units | |
Initial amount of S1 | 3.0 × 10−4 | mole |
Initial amount of S2 | 0 | mole |
Initial amount of S3 | 0 | mole |
Value of local parameter k | 1 | second-1 |
Value of local parameter k | 2 | 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.
