Organic Chemistry 6
Using Table 24.2 to assist you, draw a Fischer projection for the structure of (a) galac turonic acid, the uronic acid derived from galactose; (b) ribitol, the alditol derived from ribose.

Organic Chemistry 6
Give Fischer projections for the aldaric acids derived from both d-glucose and l- gulose. What is the relationship between these structures?

Organic Chemistry 6
Draw a Fischer projection for the aldaric acid, and a structure of the 1,4-lactone, derived from the oxidation of (a) d-galactose; (b) d-mannose.

Organic Chemistry 6
Give the product formed when each of the following alcohols is oxidized by dilute HNO3. (a) CH2OH HO (b) HOCH2CH2CH2CH2OH

Organic Chemistry 6
Explain why the methyl a-d-pyranosides of all d-aldohexoses give, in addition to formic acid, the same compound when oxidized by periodate.

Organic Chemistry 6
Assuming you knew the properties of the compound obtained in Problem 24.24, including its optical rotation, show how you could use periodate oxidation to distinguish methyl a-d-galactopyranoside from methyl b-d-galactopyranoside.
