How a glycosidic linkage is formed
WebThe linkage between the two monosaccharides is formed by a β-1,4-glycosidic bond, which refers to the specific type of covalent bond that joins the two sugar molecules together. This type of linkage is important in the structure and function of carbohydrates, as it determines the shape, stability, and chemical properties of the molecule. WebA very restrictive definition is as follows: Carbohydrates consist of carbon, hydrogen, and …
