The structure of a disaccharide formed from two galactose units joined by a 1 → 4-β-glycosidic linkage needs to be drawn. Concept Introduction: Disaccharides are carbohydrates composed of two monosaccharides. Disaccharides are acetals, compounds that contain two alkoxy groups (OR groups) bonded to the same carbon. A disaccharide results when a hemiacetal of one monosaccharide reacts with a hydroxyl group of a second monosaccharide to form an acetal. The new C-O bond that joins the two rings together is called a glycosidic linkage. The two monosaccharide rings may be five-membered or six-membered. All disaccharides contain at least one acetal that joins the rings together. Each ring is numbered beginning at the anomeric carbon, the carbon in each ring bonded to two oxygen atoms
