SFORB.solution: Single First-Order Reversible Binding kinetics
Description
Function describing the solution of the differential equations describing
the kinetic model with first-order terms for a two-way transfer from a free
to a bound fraction, and a first-order degradation term for the free
fraction. The initial condition is a defined amount in the free fraction
and no substance in the bound fraction.
Starting value for the response variable at time zero.
k_12
Kinetic constant describing transfer from free to bound.
k_21
Kinetic constant describing transfer from bound to free.
k_1output
Kinetic constant describing degradation of the free
fraction.
Value
The value of the response variable, which is the sum of free and
bound fractions at time t.
