And so here is now the basic science BEHIND the sugar molecule.

This is needed for the release of energy.

Glucose is now created and water and Carbon dioxide is released with the addition of Oxygen, the very reason we Breathe!
now, this is why Sugar is IMPORTANT to life forms that have aerobic respiration. The oxygen intake combines with glucose, which has been digested previously.
So now you have no sugar to store because you have burned it up. If you do NOT burn it up, the body utilizes a storage system which includes folding the glucose molecule in a spiral form and store it in the blood stream as cholesterol. Readily available for bursts of energy by merely accessing them through chemical efficiency and oxidation (breathing heavily during a run)

This has been for the evolution of the animal form of mammals, like us, a vital component for locomotion.

Now here come "Corn Wallets" and claims that through the complicated and at times, dangerous chemical reactions, he can take bleached corn starch and turn it into sugar, more efficiently than bees on nectar, and more available than sugar cane or beets.
 This is the HFCS molecule, which has no separators and cannot be processed in the digestive tract. It usually comes with more garbage attached to it since it is called a simple sugar. Thus now attached to it are peptides and other stomach acids that must be transmuted in the liver.

I'm researching that now, but check this article in the meantime. Trying to find images and molecular information isn't so easy.

poor rats.... but hey, there wasn't one that didn't gain weight when fed HFCS.
