Fructose

By: Aruba Tariq

What is fructose?• Fructose is a monosaccharide

• Monosaccharide: sugar that cannot be broken down into simpler sugars

• Takes two form: 5 member ring (more common) and linear form

• Boiling Point: N/A• Melting Point:• Density: • It doesn’t hydrolyze

(decompose by reacting with water) in acidic environments

103oC

1.69g / cm3

Fructose and Glucose• Fructose and glucose share

the molecular formula C6H12O6

• Structural isomer: same molecular formulas but different structural formulas

Glucose: aldohexose (carbon is attached to a hydrogen atom by a single bon and an oxygen ato by a double bond).

Frcutose: ketohexose (carbon is attached only to an oxygen atom by a single bond).

Types Of Fructose• Natural Fructose: found in

fruits and vegetable About 1-7% in fruits and 3% in vegetables

• The concentration of fructose increases in fruits as they ripen and sucrose in the fruits gets broken down into fructose and glucose (gives the fruit a sweeter taste)

• Also found in honey: about 40%

• Crystalline fructose: obtained from processing corn and suger

• 100% pure fructose in crystalline form

Uses of Fructose• Fructose can be converted

into hydroxymethylfurfural (HMF) and turned into: diesel-fuel additives, plastics, and diesel fuel itself

• Used as a sweetener (low-calorie sweetener): used by people with diabetes because of its low Glycemic Index

•Used to increase the shelf life of foods like soft moist cookies and nutrition bars

•Can be consumed as high fructose corn syrup (part of glucose is turned into fructose to give it a more sweeter taste)

Also a possible cause of obesity
