The model contains one compartment called C. There are four species called S1, S2, S3 and S4 and one parameter called k. The model contains one reaction that has a kinetic law that defines third order mass action kinetics with three reactants (as referenced by SBO:0000061):
Reaction | Rate |
S1 + S2 + S3 → S4 | k · S1 · S2 · S3 · C |
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 | 0.75 | mole |
Initial amount of S4 | 0 | mole |
Value of parameter k | 0.8 | litre2 mole-2 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.
