Fructose
Brief History of Fructose
• Fructose was first discovered in 1847 by French chemist Augustin-Pierre Dubrunfaut.
• Fructose was first used in high fructose corn syrup in 1977.It came at a time when the price of importing sugar was rising greatly.
• That cheap yet sweet alternative was high fructose corn syrup, or fructose. Fructose soon moved to replace imported sugar in almost every food, snack, and drink.

Properties
chemical properties
Fructose is a 6-carbon polyhydroxyketone. It is an isomer of glucose; i.e., both have the same molecular formula

Easy Handling

Directly obsorded by intestine
Digestion: unsorbed fructose may be caiiredinto large intestine, providing nutrients for gut flora
Metabolism: insulin resistance, obesity, elevated LDL cholesterol and triglycerides
As a redusing sugar: skin and bone damage in rats, negative effect on aging problem
Liver fuction: increase appetite and lead to weight gain
may contribute to: non-alcoholic fatty liver disease

SWEETER!!!
The large amount of consumption of fructose is strongly suspected to lead to various types of diseases. However, the healthy intake way of fructose is still beneficial to human.
