Crystalline fructose adopts a cyclic six-membered structure, called β-d-fructopyranose, owing to the stability of its hemiketal and internal hydrogen-bonding. In solution, fructose exists as an equilibrium mixture of the tautomers β- d -fructo pyranose , β- d -fructo furanose , α- d -fructofuranose, α- d -fructopyranose and keto - d ...
It is also present in the form of refined sugars including granulated sugars (white crystalline table sugar, brown sugar, confectioner's sugar, and turbinado sugar), refined crystalline fructose, as high fructose corn syrups as well as in honey. About 10% of the calories contained in the Western diet are supplied by fructose (approximately 55 g ...
Osazones are highly coloured and crystalline compounds. Osazones are readily distinguished. [5]Maltosazone (from maltose) forms petal-shaped crystals.; Lactosazone (from lactose) forms powder puff-shaped crystals.
Structural formulae (Fischer projections) of fructose (left) and glucose (right) High-fructose corn syrup (HFCS), also known as glucose–fructose, isoglucose and glucose–fructose syrup, [1] [2] is a sweetener made from corn starch. As in the production of conventional corn syrup, the starch is broken down into glucose by enzymes.

Fructose exists as a mixture of five tautomers but sucrose has only the β-D-fructofuranose form. Unlike most disaccharides, the glycosidic bond in sucrose is formed between the reducing ends of both glucose and fructose, and not between the reducing end of one and the non-reducing end of the other. This linkage inhibits further bonding to ...
High fructose syrup, made by treating dextrose solutions with the enzyme glucose isomerase, until a substantial fraction of the glucose has been converted to fructose. In the U.S. high-fructose corn syrup is significantly cheaper than sugar, and is the principal sweetener used in processed foods and beverages. [ 52 ]
They are usually colorless, water-soluble, and crystalline organic solids. Contrary to their name (sugars), only some monosaccharides have a sweet taste. Most monosaccharides have the formula (CH 2 O) x (though not all molecules with this formula are monosaccharides). Examples of monosaccharides include glucose (dextrose), fructose (levulose ...
