[In vitro intestinal absorption of sugars in the rat. Changes in concentrations of adenine nucleotides and inorganic phosphate in mucosa].
The absorption of three sugars by the rat gut: glucose, fructose and galactose, was studied in vitro' with a jejunal everted loop technique. The concentrations of the sugars in the serosal medium and in the mucosa cells were measured at given times, as well as the concentrations of ATP, ADP, AMP and inorganic P (Pi) in the mucosa cells. The time course of these concentrations was analyzed with the aid of polynomial regression, using the least squares method.
