Hi All-
Dextrose is glucose sugar refined from corn starch. It is produced by the enzyme conversion of corn starch and then refined by ion-exchange demineralization. Tastes yummy, but digests EXTREMELY quickly. High GI.
Maltodextrins are obtained by partial hydrolysis of (corn) starch whereby the basic polymeric structure is retained. The are water soluble, and tend not to be sweet. Not-as-high GI.
Remember ALL carbohydrates are eventually broken down into glucose (sugars) in the body. Dextrose will be absorbed and converted into glucose much more rapidly than maltodextrin. GI value is a measure of how quickly carbohydrates are converted into glucose.
Insulin, not glucose, is the "protein shuttle" as Kitara called it. A rapid rise in blood glucose levels is what tends to cause the release of insulin. The release of insulin will cause the human body to 1) store fat, or 2) build muscle depending on the situation.
As it relates to
muscle building, high GI post workout drinks which contain sugars AND protein, will help to supply the basic
building blocks for muscular growth (glucose/glycogen and protein) at a time when the muscle is craving (literally) glucose and protein (post-workout).
If you didn't work out and drank the same high GI drink, you'd probably just store it as fat, as there would be no need to rebuild muscle fibers that are not damaged and in need of repair, and no need to replenish glycogen stores, as they would typically not be depleted without a wourkout of some sort.
