"Cane and beet sugar
Cane sugar and beet sugar are both relatively pure sucrose. While the
glucose and fructose which are the two components of HFCS are
monosaccharides, sucrose is a disaccharide composed of glucose and
fructose linked together with a relatively weak glycosidic bond. A
molecule of sucrose (with a chemical formula of C12H22O11) can be broken
down into a molecule of glucose (C6H12O6) plus a molecule of fructose
(also C6H12O6 — an isomer of glucose) in a weakly acidic environment.
Sucrose is broken down during digestion into fructose and glucose
through hydrolysis by the enzyme sucrase, by which the body regulates
the rate of sucrose breakdown. Without this regulation mechanism, the
body has less control over the rate of sugar absorption into the
bloodstream.
The fact that sucrose is composed of glucose and fructose units
chemically bonded complicates the comparison between cane sugar and
HFCS. Sucrose, glucose and fructose are unique, distinct molecules.
Sucrose is broken down into its constituent monosaccharides – namely,
fructose and glucose – in weakly acidic environments by a process called
inversion.[13] This same process occurs in the stomach and in the small
intestine during the digestion of sucrose into fructose and glucose.
People with sucrase deficiency cannot digest (break down) sucrose and
thus exhibit sucrose intolerance.[14]"

> While I am not fan of fructose or any other sugar, I question whether HFCS can be guilty of everything with which it is charged. Sucrose is, I believe, half fructose and half glucose. HFCS is 55% fructose, 45% glucose. Do I have those figures wrong, or does that extra 5% really make that much difference?
