For example, milk sugar (lactose) is a disaccharide made by condensation of one molecule of each of the monosaccharides glucose and galactose, whereas the disaccharide sucrose in sugar cane and sugar beet, is a condensation product of glucose and fructose. Maltose, another common disaccharide, is condensed from two glucose molecules. [7]
The repeating disaccharide unit (GlcUA(1β→3)GalNAc(1β→4)) n of chondroitin sulfate. For polysaccharide nomenclature see here. R 1, R 2, R 3 may have different values. Glycosaminoglycans [1] (GAGs) or mucopolysaccharides [2] are long, linear polysaccharides consisting of repeating disaccharide units (i.e. two-sugar units).
Lactose is a disaccharide found in animal milk. It consists of a molecule of D-galactose and a molecule of D-glucose bonded by beta-1-4 glycosidic linkage.. A carbohydrate (/ ˌ k ɑːr b oʊ ˈ h aɪ d r eɪ t /) is a biomolecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogen–oxygen atom ratio of 2:1 (as in water) and thus with the empirical formula C m ...

Lactose is a disaccharide composed of galactose and glucose, which form a β-1→4 glycosidic linkage. Its systematic name is β- D -galactopyranosyl-(1→4)- D -glucose. The glucose can be in either the α- pyranose form or the β-pyranose form, whereas the galactose can have only the β-pyranose form: hence α-lactose and β-lactose refer to ...
Maltose, with two sugar units, is a disaccharide, which falls under oligosaccharides. Glucose is a hexose : a monosaccharide containing six carbon atoms. The two glucose units are in the pyranose form and are joined by an O-glycosidic bond , with the first carbon (C 1 ) of the first glucose linked to the fourth carbon (C 4 ) of the second ...
Disaccharidases are glycoside hydrolases, enzymes that break down certain types of sugars called disaccharides into simpler sugars called monosaccharides. In the human body , disaccharidases are made mostly in an area of the small intestine 's wall called the brush border , making them members of the group of "brush border enzymes".
