The Haworth projection formula for the β − anomer of the given Fischer projection formula of a monosaccharide has to be drawn. Concept introduction: The Haworth projection formula can be drawn by using the following rules. Ø For α and β configurations, if hydroxyl group is drawn at the right position in Fischer projection formula then in the cyclic form of Haworth projection, the same OH group should be drawn below the ring. Ø If hydroxyl group is drawn at the left position in Fischer projection formula then in the cyclic form of Haworth projection, the same OH group should be drawn above the ring. Ø For β configuration, the position of OH group at the first carbon with respect to CH 2 OH group always remains in the same direction. Ø For α configuration, the position of OH group at the first carbon with respect to CH 2 OH group always remains in the opposite direction. Ø The hydroxyl group that is obtained from the carbonyl group can be placed above or below the ring which is dependent upon the ring closure of the cyclic form. Ø For D configuration, CH 2 OH group always placed above the cyclic ring. Ø For L configuration, CH 2 OH group always placed below the cyclic ring.
