¹Values are mean transit times [(7), or the mean of the distribution of times that retinol entering compartment I spends there before leaving reversibly or irreversibly]; residence times [(I,5), or the mean of the distribution of times that retinol spends in compartment I after reaching plasma compartment 5]; plasma recycling number, or the average number of times retinol recycles to plasma before leaving plasma irreversibly, and recycling time, or the time required for an average retinol molecule leaving plasma to cycle back to plasma.
