Single First-Order Reversible Binding kinetics

Usage

SFORB.solution(t, parent.0, k_12, k_21, k_1output)

Arguments

t
Time.
parent.0
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.

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.

Value

The value of the response variable, which is the sum of free and bound fractions at time t.
