Thank you for the quick run through.RRM wrote: Dextrose = glucose.
Sucrose = glucose + fructose
So, in sucrose (= sugar) there is glucose and fructose,
and as they go different pathways, they kind of complement each other (as fatty acids and glucose do).
When you need much energy at once, ingesting a lot of glucose is better than ingesting a lot of fructose,
because the uptake capacity of fructose from the intestines is limited (per time).
All sugars are hydrophylic, so that sugars (likely fructose) remaining in the intestines, will retain water in the bowels
(or distract water from the blood when there is insufficient water in the intestines).
I had learned that dextrose was used in oral rehydration therapy while sucrose should not be used... but it seems to be wrong, and both work equally..
