Polysaccharides inulin pectins starch

Cellulose, hemicelluloses and inulin are insoluble non-starch polysaccharides, whereas pectin and the plant gums and mucilages are soluble. The other major constituent of dietary fibre, lignin, is not a carbohydrate at all but a complex polymer of a variety of aromatic alcohols. 

A series of polysaccharide sorption power is similar for Pb and Cd and is as follows cellulose > pectin > starch > inulin [265]. It was shown in [262-265] that there is a correlation between the weight of the solid residue of the product made of vegetable raw and its ability to sorb lead and cadmium from the solutions of their salts. The larger the solid residue weight, the higher the sorption power of the product. In addition, a decrease in BAS particle sizes yields an increase in the sorption power. Interesting results were obtained in [262-265] when... 

Plants are the most important producers of polysaccharides. Their main products are cellulose, hemicellulose, starch, inulin and pectin. Cellulose is hy far the most abundant renewable polymer available worldwide, its occurrence was estimated at some lO -lO tons per annum. ...
