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] Like monosaccharides, disaccharides are simple sugars soluble in water.
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".
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 ...
Sucrose is a disaccharide made up of 50% glucose and 50% fructose and has a glycemic index of 65. [50] Sucrose is digested rapidly, [ 51 ] [ 52 ] but has a relatively low glycemic index due to its content of fructose, which has a minimal effect on blood glucose.
Trehalose is a disaccharide formed by a 1,1-glycosidic bond between two α-glucose units. It is found in nature as a disaccharide and also as a monomer in some polymers. [7] Two other stereoisomers exist: α,β-trehalose, also called neotrehalose, and β,β-trehalose, also called isotrehalose. Neither of these alternate isomers has been ...
Lactose, or milk sugar, is a disaccharide composed of galactose and glucose and has the molecular formula C 12 H 22 O 11.Lactose makes up around 2–8% of milk (by mass). The name comes from lact (gen. lactis), the Latin word for milk, plus the suffix -ose used to name sugars.

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 ...
