Amylopectin purification

Carbamate derivatives (Table 1) of cellulose, chitin, amylose, amylopectin, and dextran were prepared using the isocyanates described in Part A of the Experimental Section. Amylose, amylopectin, dextran, and cellulose were obtained from Polysciences, Inc. and used without further purification. Chitin, obtained from Eastman Kodak, was decalcified and deproteinated by the method reported by Haye r prior to use. 

The separation and purification of starch granules from plant extracts (see O Sect. 2 in O Chap. 6.2) and the fractionation of amylose and amylopectin is given in O Sect. 5 in O Chap. 6.2. The separation of cellulose and hemicelluloses from plant materials and from each other is given inO Sect. 3.2 inO Chap. 6.3.
