The model contains one compartment called "compartment". There are three species named S1, S2 and S3 and two parameters named k1 and k2. The model contains two reactions defined as:
Reaction | Rate |
S1 + S2 → S3 | k1 · S1 · S2 · compartment |
S3 → S1 + S2 | k2 · S3 · compartment |
The model contains one rule which assigns value to compartment "compartment":
Type | Variable | Formula |
Assignment | compartment | 1 |
In this case there is no initial value declared for compartment "compartment". Thus the value must be calculated by the assignmentRule.
The initial conditions are as follows:
Value | Units | |
Initial amount of S1 | 1 × 10−5 | mole |
Initial amount of S2 | 1.5 × 10−5 | mole |
Initial amount of S3 | 1 × 10−5 | mole |
Value of parameter k1 | 1.5 × 105 | litre mole-1 second-1 |
Value of parameter k2 | 50 | second-1 |
Volume of compartment "compartment" | undeclared | 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.
