In a laboratory experiment, a student was given an unknown compound. After performing the test for carbohydrate analysis, the student reported the unknown as a reducing aldopentose. Which all tests must have led the student to arrive at this conclusion?While performing the carbohydrate analysis, one observes that sucrose gives positive result for the seliwanoff's test. Suggest a possible reason for this observation.
Assume that for your Biochemistry practical, you were asked to synthesise D-Galactose. You went to chemical storage room to take some D-lyxose to use as the starting material. But there you found that labels had fallen off from the bottles containing D-lyxose and D-xylose. How could you determine which bottle contains D- lyxose?
Best describes the relationship between the straight chain forms of D-glucose and D-galactose, given that they are non-cyclic molecules that differ only in stereochemical configuration at the fourth carbon?

This can be done either by selective oxidation or reduction. As a specific example, nitric acid oxidation of d-erythrose gives meso-tartaric acid . Similar oxidation of d-threose gives (2S,3S)-tartaric acid.
