Basic knowledge is that fructose can do little except replenish liver glycogen. It is not used preferentially its just has limited use. If your liver glycogen stores are already filled it will be more readily turn into TG's and stored as adipose since it is of relatively no use for peripheral tissues. I got my metabolism of sugars down fairly well.ss01 said:Maybe you can do a search on pubmed if you want some research, I don't know if there's any, it is fairly basic knowledge that fructose replenishes liver glycogen before anything else.
Fructose isn't metabolised as sugar by most tissue. Only the liver can turn the fructose into glucose. That is how it replenishes its glycogen stores first. Dextrose, OTOH, goes to your bloodstream, which is OK, but too much of it will trigger insulin, and it is absorbed by ALL tissue, which makes dosing for keeping the glycemia up much more difficult than using fructose. You might use some of both...
The reason why it doesn't raise blood sugar as quick as the other ones is that the liver watches glycemia and will only release new glucose from fructose IF glycemia is low enough. It is a comparatively slow process, but that's good. In other words, I'd much rather have my liver gradually release glucose into my bloodstream when I'm close to hypo than have to ingest slow/medium/fast carbs all the time and risk triggering insulin while also being on hypoglycemia inducing supplements.........
Oh, and the work involved for the liver is EXTREMELY trivial. Don't worry about THOSE enzymes... Worry about the ones trying to metabolize your methylated steroids...
