Sucrose, a disaccharide formed from condensation of a molecule of glucose and a molecule of fructose. A disaccharide (also called a double sugar or biose) [1] is the sugar formed when two monosaccharides are joined by glycosidic linkage. [2]
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.
Oligosaccharides of glucose combined with other sugars serve as important energy stores. These include lactose, the predominant sugar in milk, which is a glucose-galactose disaccharide, and sucrose, another disaccharide which is composed of glucose and fructose. Glucose is also added onto certain proteins and lipids in a process called ...
“Glucose and fructose are made up of the exact same atoms,” he continued. “The only difference between them is the way in which the atoms are arranged. Given the avidity that cancer cells ...
Likewise, gastric acidity converts sucrose to glucose and fructose during digestion, the bond between them being an acetal bond which can be broken by an acid. Given (higher) heats of combustion of 1349.6 kcal/mol for sucrose, 673.0 for glucose, and 675.6 for fructose, [ 13 ] hydrolysis releases about 1.0 kcal (4.2 kJ) per mole of sucrose, or ...
Dense inverted sugar syrup (Trimoline) Inverted sugar syrup, also called invert syrup, invert sugar, [1] simple syrup, sugar syrup, sugar water, bar syrup, syrup USP, or sucrose inversion, is a syrup mixture of the monosaccharides glucose and fructose, that is made by hydrolytic saccharification of the disaccharide sucrose.

Its monosaccharides: glucose and fructose; Their ring types: glucose is a pyranose and fructose is a furanose; How they are linked together: the oxygen on carbon number 1 (C1) of α-D-glucose is linked to the C2 of D-fructose. The -oside suffix indicates that the anomeric carbon of both monosaccharides participates in the glycosidic bond.
