Saccharides hydrolized

The enzymatic hydrolysis is the method of choice when undesired reactions are to be avoided. /Tglucosidases (or /J-glucuronidases) from Helix pomatia digestive juice are now commercially available. They usually show a good hydrolytic performance, even if sometimes need long time reactions (days). Other enzymes are reported to have been used to specifically hydrolize saccharidic bonds like hesperidinase, /J-xylosidase, j3-galactosidase, and mixed crude enzymes like cellulase. 

Reported from acid hydrol. of lipopoly-saccharides from Coxiella burnetii phase I cells. Involved in serological activity of C. burnetii LPS. [a]o +8.1 (H2O). 

In the field of the amino sugars the classical method for the elucidation of oligo- and poly-saccharide structure by permethylation, hydrol s and identification of the cleavage products, has been applicable to a limited extent only. More recently Jeanloz, Stolfyn et synthesized most of... 

Products of similar structure and composition are available by hydrolizing inulin (- fructans)-con-taining plant materials by action of the endo-inu-lase enzyme. The refined concentrated products with 85% solids consist of fructo-oligomers with 7 mono-saccharide groups.
