The number of anomeric carbon atoms that are present in the given cyclic form of D − galactose has to be stated. Concept introduction: The simplest hydrolyzed form that is obtained from the carbohydrates is known as monosaccharide. A compound that possesses a carbon atom which is attached with a hydroxyl group as well as with an alkoxy group is known as hemiacetal compound. This carbon atom that is attached with both hydroxyl group and alkoxy group is known as hemiacetal carbon. Carbon atom which behaves as a stereocenter in the cyclic form of the hemiacetal compound is known as anomeric carbon.

Question

Draw the structure of each of the following compounds: a. a polysaccharide formed by joining D-glucosamine in 1-→6-a-glycosidic linkages b. a disaccharide formed by joining D-mannose and D-glucose in a 1-4-B-glycosidic linkage using mannose's anomeric carbon c. an a-N-glycoside formed from D-arabinose and CgH;CHNH2 d. a ribonucleoside formed from D-ribose and thymine
