SFORB.solution. mkin 0.9.44.9000

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. -
