The model contains one compartment called C. There are four species called S1, S2, S3 and S4 and one parameter called k1. Species S4 is labeled as constant and therefore cannot be changed by rules or reactions. The model contains one reaction defined as:
Reaction | Rate |
S1 → S2 | k1 · S1 · C |
The model contains one rule:
Type | Variable | Formula |
Rate | S3 | 0.15 |
The initial conditions are as follows:
Value | Units | |
Initial amount of S1 | 1.5 | mole |
Initial amount of S2 | 0 | mole |
Initial amount of S3 | 0 | mole |
Initial amount of S4 | 1.0 | mole |
Value of parameter k1 | 1.5 | 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.
