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