The disaccharide maltose is shown below. It contains an a-1,4'-glycosidic linkage between two sugars. Number the carbons on each using the correct numbering scheme for sugars (the sugar on the right should be numbered 1', 2', 3', etc.). Circle the glycosidic bond. Name the two monosaccharides that make up maltose. OH Sugar 1 (left): Sugar 2 (right): Type of glycosidic bond: но- HO Sugar: Type of glycosidic bond: HO- Sugar 1 (left): Sugar 2 (right): Name the two monosaccharides that comprise lactose (shown below). Number the carbons. Name the type of glycosidic bond. HOOH OH НО HO HO- OH OH HO- Name the monosaccharide and the type of glycosidic bond in the polysaccharide galactan shown below. OH НОО OH HO- OH OH OH OH
