Skip to comments.News In Brief: Fructose may be key to weight gain

Mice that could not make or metabolize the sugar gained less than normal mice.
Mice lacking the ability to metabolize fructose dont gain nearly as much weight as normal mice do, researchers report September 10 in Nature Communications.
Fructose, which some people blame for the obesity epidemic and its related health crises (SN: 6/1/13, p. 22), shows up in high-fructose corn syrup and in table sugar, or sucrose. The body also makes home-grown fructose by modifying glucose in a process involving an enzyme called aldose reductase.

Another one of those useless ‘studies’.
breakdown - destruction of the monomer or clip the linkages?
Stay healthy, eat your honey...
Regardless of the biochemical pathways, Fructose is found in plants, as with many other compounds found in nature, we are "designed" to process it...
The end of those reactions produce molecules critical to our function. Like cholesterol, cholesterol is fantastic, without it, well, say good by to bi-lipid membranes for starters...
The issue here is dosage- stop stuffing your gob with anything that resembles an edible and most of the "modern problems" will clear up.
um, unless in San Fran or Thailand... but I digress.
Still a wacky analogy.
But lots of components can’t be boil/steam/filter/sifted out of things.
Here ya go:
“When fructose is consumed in the form of sucrose, it is digested (broken down) and then absorbed as free fructose. As sucrose comes into contact with the membrane of the small intestine, the enzyme sucrase catalyzes the cleavage of sucrose to yield one glucose unit and one fructose unit, which are then each absorbed.”
People drank soda since it was invented but after the switch from real sugar to corn syrup, bad things seemed to happen.
Sugar tasted better too.
Having been into amateur body building a long time ago, I have known about the problems with fructose long before its recent infamy. Sucrose include fructose, so too much of that is a bad thing too.
And this guy is a science writer?
One who knows better than to piss off Big Corn - thus softening the blow with, "Sugar causes it, too." :)
Funny, I prefer the taste of corn syrup (100% glucose) to sugar (sucrose which is metabolized to 50% glucose and 50% fructose). You might be confused and instead mean "high-fructose corn syrup" which is normal corn syrup catalyzed to about 55% fructose and 42% glucose. This ratio, incidentally, is the same as natural honey. The only real difference between natural honey and synthetic high fructose corn syrup is the traces of pollen in the honey.
if you have any interest, pick up a biochemistry text, truly amazing to understand some of the chemistry of our bodies.
here's an interesting biochem tip- if you happen to drink a wee bit much, drink something with a lot of glucose (or sucrose) before going to bed. For the extra credit, why?
a mixture can be separated by mechanical/physical means. So the sugar in 'grape drank' can separated by boiling off the aqueous portion and crystalizing the sugar. The sugar molecule however will remain unchanged.
or in biology, I can spin your blood down and separate the solids and the bits but the oxygen bonded to your prosthetic group of the porphyrin rings will remain chemically bonded.
You’re giving me the tutorial now?
Just sharing my enjoyment of chemistry ...
Oddly, Mexico does not allow HFCS to be used in soft drinks, raw sugar only. Big Lots sells some Mexican soft drinks, including imported Coca-Cola! You can get that old-fashioned taste for about a dollar a bottle (yes they are still in the old green glass Coke bottles!)...............
Too much of anything can be bad for you, health-wise, but HFCS should be very limited intake........
They keep reusing those bottles.
