Sugars can be transformed into some other derivatives using different types of reagents inducing oxidizing and reducing agents.

a) How you form sugar alcohols and sugar acids? Write 2 model reactions with any sugar and reagent that you pick.

b) In the monosaccharide derivatives known as sugar alcohols, the carbonyl oxygen is reduced to a hydroxyl group. For example, D-glyceraldehyde can be reduced to glycerol. However, this sugar alcohol is no longer designated D or L. Why?
