In a sugar, the D or L designation refers to the configuration of the chiral carbon farthest from the aldehyde or keto group. This is C-5 in glucose. In a Fischer projection, the highest numbered chiral carbon has the OH group pointing to the right. D- and L-sugars are mirror images of one another.

    beta-D-Fructofuranose | C6H12O6 - PubChem

    Fructose, or levulose, is a levorotatory monosaccharide and an isomer of glucose (C6H12O6). The chemical composition of fructose is (C6H12O6). Pure fructose has a sweet taste similar to cane sugar, but with a "fruity" aroma. Although fructose is a hexose (6-carbon sugar), it generally exists as a 5-member hemiketal ring (a furanose). This structure is responsible for the long metabolic pathway .

    the identity of the sugar. The previous cyclic structure for D-allose shows that the hydroxyl groups on C-2, C-3, and C-4 are all oriented toward the bottom face of the ring, while the CH 2 OH group on C-5 is oriented toward the top face of the ring. Placing these groups on the structure gives the following Haworth structure for D-allose.
