The model contains one compartment called C. There are three species called S1, S2 and S3 and three parameters called k1, k2 and p1. Compartment C is 1-dimensional. The model contains two reactions defined as:
Reaction | Rate |
S1 + S2 → S3 | k1 · S1 · S2 · C |
S3 → S1 + S2 | k2 · S3 · C |
The model contains one initialAssignment:
Variable | Formula |
C | p1 · 2 |
Note: SBML's InitialAssignment construct override any declared initial values. In this case the initial value declared for compartment C is consistent with the value returned by the InitialAssignment.
The initial conditions are as follows:
Value | Units | |
Initial amount of S1 | 1.0 | mole |
Initial amount of S2 | 2.0 | mole |
Initial amount of S3 | 1.0 | mole |
Value of parameter k1 | 3.5 | metre mole-1 second-1 |
Value of parameter k2 | 1.5 | second-1 |
Value of parameter p1 | 0.5 | metre |
Length of compartment C | 1 | metre |
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.
