Absorption of monosaccharides, in vitro, from the gut of the echiuroid, Urechus caupo

The purpose of these studies was to obtain evidence for the active transport of monosaccharides by the gut of the U. Caupo by determining if D-glucose, D-galactose, 3-0- methyl-D-glucose and/or D-mannitol wore absorbed against a concentration difference, and if this ability was specific for one or more of these monosaccharides.
