The structure of dextran.

Of recent years, following the elucidation of the constitution and structure of the more common mono and d1~aooharides, the attention of oarbohydrate ohemistshas been focussed more and more strongly on the higher polysaccharides. For example, among the plant polysaccharides, it has been definitelyestablished that cellulose and starch are long linear chains of anhydroglucose units. In the case of inulin and levan, the chain 1s made up ofanhydro-fructose units, while xylan and other pentosans are linear anhydro-pentose polymers. [...
