Fructose and HFCS: Once again the "skeptics"* are wrong.

104. Not really - needs to undergo hydrolysis, a chemical reaction.

Sucrose can actually stay in solution for a long time without separating into fructose and glucose if needed enzymes are not present. https://en.wikipedia.org/wiki/Sucrose

Hydrolysis breaks the glycosidic bond converting sucrose into glucose and fructose. Hydrolysis is, however, so slow that solutions of sucrose can sit for years with negligible change. If the enzyme sucrase is added, however, the reaction will proceed rapidly.[11] Hydrolysis can also be accelerated with acids, such as cream of tartar or lemon juice, both weak acids. Likewise, gastric acidity converts sucrose to glucose and fructose during digestion the bond between them being an acetal bond which can be broken by an acid.


What I meant to say is that more study is needed to assess he differences of metabolism between sucrose and HFCS in terms of possible health effects. http://advances.nutrition.org/content/4/2/236.full

Taken together, these findings suggest that we must be very cautious when attributing adverse health consequences to the consumption of fructose, HFCS, or sucrose, particularly at normal population consumption levels. More randomized, controlled trials at normal levels of consumption using commonly consumed sugars are necessary to resolve these issues. In the meantime, it is important to recognize that scientific debates of this nature do not take place in a vacuum. These discussions have enormous potential to confuse and alarm the public, making the need to frame results with appropriate caution and minimize speculation imperative.
