question 29

Essay

A pentose of the D-family gave an optically active glycaric acid (a dicarboxylic acid)on oxidation with nitric acid.The pentose was converted by the Kiliani-Fischer Synthesis into a pair of diastereoisomeric hexoses,one of which gave an optically active glycaric acid when oxidized with nitric acid and the other of which gave an optically inactive glycaric acid.What are the names and structures of the pentose and the two hexoses?
