Please expound on this unique metabolic mechanism and how it differs from any other carbohydrate like, say, sugar (sucrose).

American Journal of Clinical Nutrition, November 2002 Vol. 76, No. 5, 911-92

"Glucose is metabolized in every cell in the body but all fructose must be metabolized in the liver.6 The livers of test animals fed large amounts of fructose develop fatty deposits and cirrhosis, similar to problems that develop in the livers of alcoholics."

Fructose is No Answer For a Sweetener

"Pure fructose contains no enzymes, vitamins or minerals and robs the body of its micronutrient treasures in order to assimilate itself for physiological use. While naturally occurring sugars, as well as sucrose, contain fructose bound to other sugars, high fructose corn syrup contains a good deal of "free" or unbound fructose. Research indicates that this free fructose interferes with the heart’s use of key minerals like magnesium, copper and chromium. Among other consequences, HFCS has been implicated in elevated blood cholesterol levels and the creation of blood clots. It has been found to inhibit the action of white blood cells so that they are unable to defend the body against harmful foreign invaders."

Yes, fructose is converted by the liver into glucose. We've known this for a long, long time.

The livers of test animals fed large amounts of fructose develop fatty deposits and cirrhosis, similar to problems that develop in the livers of alcoholics."

Cramming lab rats full of chemicals that has absolutely no relationship to real world consumption by humans will cause all sorts of maladies to occur within the animal. Humans, on average, derive less than 8% of their total calories from fructose. No human consumes straight fructose. So how is it relevant that a lab rat is fed 25%, or more, of its total calories from straight fructose?

Pure fructose contains no enzymes

Why would this matter? Your body produces all the enzymes it needs.

vitamins or minerals and robs the body of its micronutrient treasures in order to assimilate itself for physiological use

Micronutrient treasures robbed? LOL! That's loopy. Why should HFCS, or sugar for that matter, supply vitamins and minerals?

While naturally occurring sugars, as well as sucrose, contain fructose bound to other sugars, high fructose corn syrup contains a good deal of "free" or unbound fructose.

A "good deal" of "free or unbound fructose?" All of the fructose in HFCS is free/unbound.

Research indicates that this free fructose interferes with the heart’s use of key minerals like magnesium, copper and chromium.

This is more nonsense. Sugar (sucrose) is hydrolyzed in the gut into free fructose and glucose. If HFCS causes this to happen (it doesn't) then so does sugar (sucrose). Both sucrose and HFCS are made up of the same two chemicals (fructose and glucose) so how can one interfere with your heart while the other does not?

Among other consequences, HFCS has been implicated in elevated blood cholesterol levels and the creation of blood clots. It has been found to inhibit the action of white blood cells so that they are unable to defend the body against harmful foreign invaders."

This is nutty but if it were true you'd have to say the same thing about regular old table sugar.

I found this from the link you provided:

Most corn syrup is 97% glucose yet this wacky website wants you to believe that corn syrup is made from fructose. If they can't even get this simple fact right how much of what they write is also suspect? I'd say most of it. There is a lot of misinformation on the internet and you've found some of it.

As for HFCS having a "unique metabolic mechanism that differes from other carbohydrates....."

Sugars and satiety: does the type of sweetener make a difference?

HFCS and sugar have similar metabolic mechanisms (April 7, 2006)

At this time, there is no scientific evidence to suggest that humans utilize either HFCS-42 or HFCS-55 any differently than sucrose, invert sugar, or honey. All disaccharides are completely hydrolyzed in the gastrointestinal tract into their simple sugar (monosaccharide) components prior to absorption. In order to hydrolyze sucrose into fructose and glucose, the small intestine secretes an enzyme known as sucrase, which is abundant and not rate -limiting. Consequently, the rate of absorption for the monosaccharide components of sucrose and HFCS is likely to be equal in both speed and completeness.

Fructose and glucose are absorbed and metabolized differently by the human body.10,11 However, fructose is fructose and glucose is glucose regardless of the source-HFCS, sucrose, invert sugar, or honey. In other words, after hydrolysis in the gut, the monosaccharides derived from these sweeteners are physiologically indistinguishable to the human body.

It's a subscription site so I am unable to link you to it.
