Re: High Fructose Corn Syrup

[Guest guest]

The carbonyl group is basically -(C=O)-. It is present in acids,

aldehydes, and ketones. Sugars like fructose are called " ketoses "

because they have a carbonyl group in the second carbon of the carbon

backbone.

Carbonated water consists of H20 and C02 which becomes carbonic acid

H2C03 and can produce bicarbonate and carbonate ions. Reactive

carbonyl groups are more likely to come from the carbonated water than

from the sugars. I don't think that it is possible to conclude that

the reactive carbonyl groups in a carbonated beverage come from the

HFCS and not from the carbonated water unless the experiments are

carried out with labeled carbon atoms. Reactive carbonyl groups may

also be formed when plain sugar (sucrose) is dissolved in carbonated

water, or they may be present in plain carbonated water like seltzer

or club soda.

The chemistry in the press report is so vague, that you can only

conclude that soft drinks may be bad for your health, but nothing else.
