Is There a Similar Ceiling for Glucose Transporters?

For glucose transporters that ceiling is around 60 grams an hour. Do we know if there's a similar ceiling for the fructose transporters and roughly where that would be? That doesn't seem to be, or at least I can't, if I go back to the, to the literature, I can't really see what that ceiling is. What the limiting factor there is just GI problems. We know that if you just give fructose without the glucose, that's a great recipe to get some diarrhea and all sorts of GI problems. As soon as you add glucose though, that really helps the fructose absorption and also the other way around. If you give the same amount of glucose versus
