The model contains one compartment called C. There are two species called S1 and S2 and two parameters called k1 and k2. The model contains one reaction defined as:
Reaction | Rate |
S1 → S2 | C · k1 · S1 |
The model contains one initialAssignment:
Variable | Formula |
k1 | division(k2, 100) |
The initialAssignment uses a functionDefinition defined as:
Id | Arguments | Formula |
division | x, y | xy |
Note: SBML's InitialAssignment construct override any declared initial values. In this model, the initial value for the parameter k1 has not been explicitly declared and must be calculated using the InitialAssignment.
The initial conditions are as follows:
Value | Units | |
Initial amount of S1 | 1 | mole |
Initial amount of S2 | 1.5 | mole |
Value of parameter k1 | undeclared | second-1 |
Value of parameter k2 | 50 | 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) they must be treated as concentrations where they appear in expressions.
