The quantities a and have units of concentration, so if all concentrations (nutrients, organisms, and Michaelis-Menten constants) are measured in units of then S may be scaled out of system (2.1). Similarly, the units of m , and D are reciprocal time, so with an appropriate change of time scale D may also be scaled out of the system. Moreover, the conversion factors 7 and 7 can be incorporated into m, and f,. This is essentially the scaling that has been used in all of the previous models. With these changes of scale, the new system takes the form... 

Humans can absorb up to 50% of dietary copper in the gastrointestinal tract, depending on the presence of other interfering nutrients. Organic complexes facilitate the transport of Cu through the cell walls. Ab-...
