HFCS is usually 55% fructose and 42% glucose with table sugar being roughly 50/50 fructose and glucose.
The only practical difference between sucrose and HFCS is in the bonding. The glucose and and fructose in HFCS is free and unbounded, while glucose and fructose are bonded in sucrose. However, this makes no actual difference in regards to being metabolized in the body. The bonds are broken quickly once the sucrose hits the acidic environment of the stomach.
As far as your body is concerned, other than the ratio of fructose to glucose, the two are identical.
This translates into why HFCS is no worse or better than sugar.
