Fructose (/ ˈ f r ʌ k t oʊ s,-oʊ z /), or fruit sugar, is a ketonic simple sugar found in many plants, where it is often bonded to glucose to form the disaccharide sucrose.It is one of the three dietary monosaccharides, along with glucose and galactose, that are absorbed by the gut directly into the blood of the portal vein during digestion.

The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
The DHAP formed during fructolysis can also be converted to glycerol and then glycerol 3-phosphate for TG synthesis. Thus, fructose can provide trioses for both the glycerol 3-phosphate backbone, as well as the free fatty acids in TG synthesis. Indeed, fructose may provide the bulk of the carbohydrate directed toward de novo TG synthesis in ...
This polymer is made up of fructose, a monosaccharide sugar, connected by 2,6 beta glycosidic linkages. Levan can have both branched and linear structures of relatively low molecular weight. [ 2 ] Branched levan forms a very small, sphere-like structure [ 3 ] with basal chains 9 units long.

A fructan is a polymer of fructose molecules. Fructans with a short chain length are known as fructooligosaccharides . Fructans can be found in over 12% of the angiosperms including both monocots and dicots [ 1 ] such as agave , artichokes , asparagus , leeks , garlic , onions (including spring onions ), yacón , jícama , barley and wheat .
Kestoses are typical fructooligosaccharides, and in its structure, one fructose molecule is combined with sucrose to form a trisaccharide. In the 1-kestose type, the fructose molecule will be connected to sucrose by a (1→2β) glycosidic bond. Different types of kestoses have different lengths of subunits in the chain, for example, 6-kestose ...
