Revision as of 20:50, 30 September 2005
What do you mean that some people react badly to fructose??
Full blown misguided views on health effects
I added a NPOV warning for the following reasons :
Full blown misguided studies/articles about health effects : Why would fructose cause obesity if it's slower to digest than sacharose and also more sweeter for less calories, and also les likely to drive any addiction, the study about obesity is absolutly ridiculous and should ne withdrawn from that page! And the other healt effect can be submited to the same considerations!
More considerations about health effect of fructose may be described as detrimental by the sugar industry because it makes huge profit on the addictive properties of glucose and sucrose that are often detrimental to the health because of poor mineral content, trigering insuline rush through hypo/hyper glycemia vicious cycles! In reallity fructose is much healtier than glucose and sucrose because :
- it's slower to digest therefore the pancreatic function is not overloaded, as a side effect it's very much tolerated by diabetic people! - because it's often absorbed with fruits it's associated with many highly valuable nutriments! - because fructose (the sugar of fruits in most cases) has been arround humans and ancestors for million of years (we know something about roots sugar just from industrial time) the human body is very much acclimated to fructose consumption, and fructose can be considered for historical reasons to be the main physiological sugar for oral consumption. - nowdays we eat about 100 times more sugar than our ancestors 200 years ago!
We recall here that huge profit are made from addictive substances, sucrose/glucose can easily become addictive with many consequences : diabetis, tooth decay, probably hyper-activity and some burst of violence actually the main recommendation for glucose absorbtion is before an intense burst of physical activity! Not everyday for most people.
- Just because you don't agree with the article, it doesn't mean that it is biased. The linked study does not appear unscientific to me. If indeed a diet high in fructose leads to obesity in laboratory animals, and the same effect is considered likely in humans, then this is certainly worth mentioning in Wikipedia. --221.249.13.34 05:20, 22 September 2005 (UTC)
- Agree with previous poster, just because you don't agree doesn't mean it's not true!

Structures of L Forms
I have removed these structures from the article because they seem incorrect to me. They are not mirror images of the α-D and β-D forms. The two "front-most" hydroxyls need to be "flipped". I think that the strucures shown are not fructose at all, but some other ketohexose.

I'm sorry about that, and taking a long time to fix it. I've updated the images, can they be included now? [[User:Sverdrup|User:Sverdrup]] 08:16, 8 Sep 2004 (UTC)
They look right to me now. Josh Cherry 01:18, 9 Sep 2004 (UTC)
These graphics are still incorrect. In each graphic, where ever CH3 or H3C is found, it should be CH2 or H2C respectively. Thank you for placing these graphics online.... but they need to be accurate before they are borrowed and end up on websites and student papers all over the world. User: Don DeWitt 1 Nov 2004
The same problem exists for the D-isomers. I have created revised images in Photoshop but I do not know how to upload them. The original author may wish to make these corrections and obviously knows how to do it. User: Don DeWitt 1 Nov 2004
One last thought. It would be very helpful if the carbons were numbered in all the graphics. User: Don DeWitt 1 Nov 2004
YAY FOR FRUCTOSE!!! THE BEST MONOSACCHRIDE EVER!!!!! YOU KNO IT!! ;)
