The model contains one compartment called C. There are four species called S1, S2, S3 and S4 and two parameters called kf and kr. The model contains one reaction defined as:
Reaction | Rate |
S1 ↔ S2 + S3 | (kf · S1 − kr · S2 · S3) · C |
The model contains one rule which assigns value to species S4:
Type | Variable | Formula |
Assignment | S4 | 0.5 · S1 |
In this case the initial value declared for species S4 is inconsistent with the value calculated using the assignmentRule. The calculated value should be used.
The initial conditions are as follows:
Value | Units | |
Initial amount of S1 | 1.0 | mole |
Initial amount of S2 | 0.5 | mole |
Initial amount of S3 | 0 | mole |
Initial amount of S4 | 5 | mole |
Value of parameter kf | 2.5 | second-1 |
Value of parameter kr | 0.2 | litre mole-1 second-1 |
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.
