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 ...
For example, a glucose polymer is named glucan, a mannose polymer is named mannan, and a galactose polymer is named galactan. When the glycosidic linkages and configurations of the monosaccharides are known, they may be included as a prefix to the name, with the notation for glycosidic linkages preceding the symbols designating the ...
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 table sugar used in everyday vernacular is itself a disaccharide sucrose comprising one molecule of each of the two monosaccharides D-glucose and D-fructose. [2] Each carbon atom that supports a hydroxyl group is chiral, except those at the end of the chain. This gives rise to a number of isomeric forms, all
High fructose corn syrup (HFCS) [1] – made from corn starch, containing from 55% fructose [3] to 90% fructose. High maltose corn syrup – mainly maltose, not as sweet as high fructose corn syrup; Honey [1] – consists of fructose and glucose; Inositol [2] – naturally occurring sugar alcohol. Commercial products are purified from corn.

These prefixes are attached to the systematic name of the molecular graph. So for example, D-glucose is D-gluco-hexose, D-ribose is D-ribo-pentose, and D-psicose is D-ribo-hexulose. Note that, in this nomenclature, mirror-image isomers differ only in the ' D '/' L ' prefix, even though all their hydroxyls are reversed.
One glucose and one fructose: α(1→3) Maltulose: One glucose and one fructose: α(1→4) Leucrose: One glucose and one fructose: α(1→5) Isomaltulose: One glucose and one fructose: α(1→6) Gentiobiulose: One glucose and one fructose: β(1→6) Mannobiose: Two mannoses: Either α(1→2), α(1→3), α(1→4), or α(1→6) Melibiose: One ...
