Disaccharides Disaccharides are carbohydrates composed of two monosaccharide units that are joined by a carbon-oxygen-carbon linkage known as a glycosidic linkage. Circle the disaccharide linkage in each of these disaccharides below. OH glucose OH HO HO OH HO HO HO но OH HO- HO OH OHO- HO OH HO glucose OH OH glucose OH OH OH glucose galactose -OH OH fructose maltose lactose sucrose There are different types of glycosidic linkages. They are characterized by the numbering of the alcohols that are linked in the ether. And the anomer of the sugar. For the maltose shown here, the sugars are [a/ẞ] anomers.
