NOW Foods, Fructose Fruit...
Also known as "fruit sugar", fructose is roughly 50% sweeter than ordinary... More |
...Crystalline fructose and high-fructose corn syrup are often confused as the same product. Crystalline fructose, which is often produced from a fructose-enriched corn syrup, is indeed the monosaccharide. High-fructose corn syrup, however, is usually considered to be a mixture of nearly equal amounts of fructose and glucose. Read full entry

What is the difference between I've read that fructose and
lactose are more complicated
sugars.
Is this the only difference?
Are fructose and lactose
broken down into glucose by
our bodies anyway?

Glucose and Fructose are monosaccarides and are Isomers of the same chemical formula: C6,H12,O6 the difference between the molecules is the two is the placement of two bonds. Fructose must be converted into glucose before it can be used by the body. Glucose does not need to be digested before it can be used. Lactose is a disaccharide (made up of 2 monosaccarides) Lactose is formed when Glucose and Galactose join together in a reaction called dehydration synthesis. Basically yes, fructose and lactose are converted to glucose to be absorbed into the bloodstream. |

Can your digestive system I've heard Dr Andrew Weil say
that people can survive on
intervenous feeding of glucose
alone for quite some time but
very little time on fructose.
I believe he was implying that
fructose is an inferior sugar.
But isn't the body's digestive
system able to convert
fructose into glucose in any
event? Any savy nutritionists
or doctors out there who can
give me insight?

In biochemistry is was said that fructose is converted into glucose in the liver. Now keep in mind, when someone says digestive system they are usually talking about the stomach and intestines. Lets go over a few things: 1. Fructose is just an isomer of glucose. Isomers are easily converted between each other, if you have the right enzymes. 2. Fructose is not directly used in creating energy for the body, it must first be turned into "glucose like" molecules /----> GA -----\GAK FK F1P ald / \ fru -------> fru-1-P ---------- -------> 2 GA-3-P - - - - > \ / \---> DHAP ----/izo 3. No energy is used in this system (thats not to say energy isn't used in the creation of the enzymes). Once you have 2 Glyceraldehyde 3-Phosphate molecules, you are ready to begin the Krebs cycle, and its from this you get most of your ATP (the bodies energy) Anyway, in the human body Its almost safe to say their are no closed systems. As long as molecules can be converted into something of use, you can live. |

How does cornstarch turn into If I heat cornstarch and water
(or milk) in a small saucepan
and stir, will the sugar
content go up? Does this turn
it into high fructose corn
syrup?

a viscous, sweet syrup produced by breaking down (hydrolyzing) cornstarch, either by heating it with a dilute acid or by combining it with enzymes. (Cornstarch is a product of corn [maize].) Light corn syrup has been clarified and decolorized |
