In HFCS-55, the kind used in soft drinks, it's 55 percent fructose and 42 percent glucose. I used to think all 6 carbon sugars are the same. If you check out the first link, you'll learn that fructose can easily go into de novo lipogenesis. So with HFCS-55, you're getting almost 4 moles of fructose for every 3 moles of glucose.
That is definitely over-fructosed compared to ordinary sugar. Funny that pure fructose can be had in “health food stores” as a supposed calorie cutter for culinary purposes. Seems that most people would be better off using ordinary sugar.
