After a series of Kiliani-Fischer syntheses on D-glyceraldehyde, an unknown sugar was isolated from the reaction mixture. The following experimental data was obtained. What is the structure of this unknown sugar? Data: - Molecular formula: C6H12O6 - Reacts with phenylhydrazine to give an osazone, mp 178°C. - Reacts with HNO3 to give an optically active aldaric acid. - Wohl degradation followed by HNO3 oxidation gives an optically inactive Aldaric acid. - Two Wohl degradations followed by HNO3 oxidation give a meso-tartaric acid.
