A powdered microcrystalline form of this polymer is the most common binding excipient used in drug manufacturing. Carbon disulfide (0[1])solubilizes this polymer and regenerates it into rayon. (20[1])This polymer is purified (20[1]0[1])by a pressure cooker full of white liquor in the kraft process. (20[1]0[1])Acetate (20[1])films (20[1])are made from this polymer’s (0[1])acetate ester, and its nitrate ester (0[1])dissolves proteins in Western blotting membranes. This polymer, its branched (*) “hemi-” derivative, (0[1])and lignin are used to make ethanol (10[1])biofuels. (10[1])The beta-1,4-glycosidic (10[3])bonds in this linear polymer (10[1])give its fibers (10[1])rigidity (10[1]0[1])but make it (10[1])difficult (10[1])to hydrolyze, (10[1])except by ruminants. (10[1])For 10 points, paper pulp is made from what (10[1])natural (10[2]0[1])polymer (10[1]0[1])of glucose (10[1])found in plant cell walls? (10[1])■END■ (10[11]0[3])
