Separation and Purification of Carbohydrates 1.2) requiring a wide variety of analytical and separation methods. This chapter is divided into three sections based on the following physical properties of the carbohydrates: unprotected/neutral; unprotected/charged; and protected (Fig. 1). This chapter will focus on preparative methods that are

General Occurrence of Carbohydratesconstituents in plants, animals, and microorganisms. They are formed . in the process of photosynthesis. The process uses the energy of sunlight to combine carbon dioxide with water to form carbohydrate and molecular oxygen as abbreviated in the following reaction: 6 CO.+6 H.O→C.H.O.+6O.. Carbohydra

Reactions at Oxygen Atomsis means that the hydroxy-protection is the major problem in this chapter. As carbohydrates contain many hydroxy groups with similar chemical character, and since the respective hydroxy groups play different biological roles depending on their positions, selective protection of particular hydroxy gr

Deoxygenationsugars. Deoxy sugars of this type are found in many naturally occurring oligosaccharides, more commonly as deoxyaldoses than as deoxyketoses. Three of them are particularly important: (i) L-rhamnose (6-deoxy-L-mannose) found in plant and also in bacterial polysaccharides;

Anhydrosugarssynthesis. These derivatives might be divided into four main classes depending on the size of the heterocyclic ring i.e., oxiranes (e.g., 1), oxetanes (e.g., 2), THF derivatives (e.g., 3), and THP derivatives (e.g., 4; Fig. 1.). The latter are very rare and only limited examples can be found in lite
