The remarkable performance of P-6 in the separation of oligosaccharides, particularly of glucans and fructans, is well known (31,32) and is illustrated... 

Cyclodextrins (CDs) were first observed by Villiers (i) nearly a century ago. First thought to be a mysterious crystalline form of starch, the structure and chemistry of these unique cyclic glucan oligosaccharides have been elucidated through the contributions of Schardinger, Freudenburg, Cramer and French (2). 

In this paper, it has been shown that glucansucrases with different synthetic specificities can synthesize glucans with different structures and can synthesize oligosaccharides with different structures by acceptor reactions. The mechanisms by which these enzymes carry out the polymerization and by which the acceptor reactions occur has been discussed. The products resulting from the... 

Functioning in a somewhat different way in E. coli are 6- to 12-residue periplasmic membrane-derived oligosaccharides. These are p-1,2- and P 1,6-linked glucans covalently linked to sn-l-phospho-glycerol, phosphoethanolamine, or succinate (see Fig. 8-28).b e/f They accumulate in the periplasm when cells are placed in a medium of low osmolarity.
