fructose and dextrose are identical chemically (the same number of hydogens, carbons and oxygens atoms,) both are sugars.

dextrose is called dextrose because it causes polorized light to bend to the right, (polorized light passed through fructose bends left)

(dextrose was first isolated by processing corn starch (with sulfuric acid, as i recall) to create corn syrup (15 to 23% dextrose) since the first attempts, processing has improved, and now HDCS-- high dextrose corn syrup- can be as much as 90% dextrose.

like fructose, dextrose seems sweeter than common sugar (sucrose).

The sugars that cause gas are: raffinose, lactose, fructose, and sorbitol.

is sorbitol a sugar? i thought it was a sweet alcohol (see the ol ending, not the ose ending) I know that not all sugars end in "ose', but most do. (glucose, sucrose, dextrose, and the previously mentioned raffinose, lactose and fructose

"sugar free' candies are sometimes made with sorbitol, (and there are warning on them, that they can increase blood sugar levels, as well as cause 'intestional disstress' if eaten in quanities.)

And sugar-free candies are also sometimes made with corn syrup--and that fact makes my blood boil! As if!
