Starch is composed of α-amylose and amylopectin. The structure of α-amylose consists of long polymer chains of glucose units connected by an α (1-4) linkage. Amylopectin consists mainly of α (1-4) linked glucose residues but is a branched molecule with α (1-6) branch points every 24 to 30 glucose residues on average. As a result of the bond angles in the α (1-4) linkage‚ amylose actually forms a spiral much like a coiled spring. Amylose is responsible for the formation of a deep blue color in the presence
