Most early publications on bacterial polysaccharides were concerned with impure products and poorly-described organisms. Many more recent papers are of limited value also, due to low yields, lack of characterization of products and arbitrary interpretations of data. Low yields of methylated polysaccharides may be due to degradation of the bacterial polysaccharide during methylation, or to degradation of the hydrolytic products of the methylated polysaccharide (to form methyl levulinate, etc.46). The great importance of (a) complete methylation of polysaccharide products prior to structural determination by hydrolysis and (6) quantitative identification of the hydrolytic products, has been emphasized previously. Other difficulties in end group analysis have been discussed recently.7... 

Reducing end-group analysis (Smith and Montgomery, 1956) is implicitly the most direct way to determine molecular weights of linear polysaccharides, because a chemical reaction establishes one-to-one correspondence between... 

The polyarabinose preparation ([a]Jj + 27.1°) of Mora and coworkers174 was subjected to methylation analysis by Dutton and Unrau.1 0 In common with other synthetic polysaccharides prepared by this method, the poly-arabinose had a highly ramified structure 16% of the nonreducing end-groups of the polysaccharide were furanoid, as indicated by the isolation of...
