Every now and again, I read something on this board that tells me it's time to re-post this information.
Here goes!
The sugar in your blood is a simple sugar called Glucose. Most of the time it's in a ring shaped form. The sugar in your coffee is called Sucrose, It's made up of a glucose molecule chemically linked to another simple sugar called fructose.[These simple one ring sugars are called monosaccharides]. 2 monosaccharides chemically linked makes a "Double" sugar called a disaccharide. digestive enzymes unlink these molecules. So if you ingest a molecule of sucrose, a single molecule of glucose enters your blood. Fructose is processed differently and ends up in your liver.
Starches are made up of very long straight or branched chains of linked glucose molcules. If your digestive enzymes completely unlink a starch molecule, you end up with hundreds of glucose moleculees in your blood.
There are quite a few different mono saccharides and hence lots of disaccharides and some trisaccharides and loads of polysaccharides [many monosaccharides linked] Some of these molecules don't exist in nature, but can be synthesized easily in a lab.
It is definitely confusing to many people to have the word "Sugar" used to describe different things.
