Fructose
Fructose, or fruit succar, is a semple monosaccharide foond in mony plants, whaur it is eften linkit tae glucose furmin sucrose. It is ane o the three dietary monosaccharides, alang wi glucose an galactose, that are absorbed directly intae the bluidstream durin digestion. Fructose wis discovered bi French chemist Augustin-Pierre Dubrunfaut in 1847.[3] Pure, dry fructose is a very sweet, white, odorless, crystalline solit an is the maist watter-soluble o aw the succars.[4]Frae plant soorces, fructose is foond in honey, tree an vine fruits, flouers, berries, an maist ruit vegetables. In plants, fructose mey be present as the monosaccharide or as a molecular component o sucrose, which is a disaccharide.

Commercially, fructose frequently is derived frae succar cane, succar beets, an corn an thare are three commercially important furms. Crystalline fructose is the monosaccharide, dried, grund, an o heich purity. The seicont furm, heich-fructose corn syrup (HFCS) is a mixtur o glucose an fructose as monosaccharides. The third furm, sucrose, is a compound wi ane molecule o glucose covalently linkit tae ane molecule o fructose. Aw furms o fructose, includin fruits an juices, are commonly added tae fuids an drinks for palatability an taste enhancement, an for brounin o some fuids, sic as baked guids.
Aboot 240,000 tonnes o crystalline fructose are produced annually.[5]
