Packet 8: Tossup 3

Fibrils and crystals of this substance are nanospray-dried into powders used to reinforce polymer composites. Nanocrystalline forms of this substance are generated via acidic hydrolysis, and aggregate into hydrogels used to grow 3D cell cultures. A carboxy-methyl substituted form of this substance (10[1])is used as a thickener or a drug dissolution agent when mixed with sodium salts. Copper (10[1])hydroxide mixed with liquid ammonia forms a bright blue reagent that dissolves (-5[1])this substance (10[1]-5[1])named for Matthias Schweizer. PVDF or a nitro derivative (10[1])of this (10[1])material (10[2])is used in the membrane of a (10[1])western blot, and is spun into fibers (10[1])to make rayon. (10[1])Before (10[1])PET, acetate esters (10[1]-5[1])of this material were used to create photographic film. For 10 points, beta-1,4 glycosidic (-5[1])bonds between glucose monomers generates what biopolymer (10[1])found in plant (10[1])cell walls? (10[3])■END■ (10[3])
