(18) Since intestinal sodium absorption was so enhanced by an actively transported sugar, fructose and galactose perfusion fluids were prepared, and it was found that fructose was less well absorbed than glucose or galactose: in general, the results with these sugars were consistent with the sodium-dependent active transport of galactose and the passive transport of fructose, unrelated to sodium transport.

Glucose
Definition:
(n.) A variety of sugar occurring in nature very abundantly, as in ripe grapes, and in honey, and produced in great quantities from starch, etc., by the action of heat and acids. It is only about half as sweet as cane sugar. Called also dextrose, grape sugar, diabetic sugar, and starch sugar. See Dextrose.
(n.) Any one of a large class of sugars, isometric with glucose proper, and including levulose, galactose, etc.
(n.) The trade name of a sirup, obtained as an uncrystallizable reside in the manufacture of glucose proper, and containing, in addition to some dextrose or glucose, also maltose, dextrin, etc. It is used as a cheap adulterant of sirups, beers, etc.
