Amylase detection of amylose

amylose is a polysaccharide chain connected by a - (1,4) glycosidic bonds between D-glucose groups. There are about 200 glucose groups in the molecule, with a molecular weight of 1-2105 and a degree of polymerization of 990. The spatial conformation is coiled into a spiral shape, with each rotation forming 6 glucose groups. In addition to the sugar chains with a - (1,4) glycosidic bonds, there are also branches connected by a - (1,6) glycosidic bonds in branched starch molecules, which contain 300-400 glucose groups and have a molecular weight of> 2107, with a polymerization degree of 7200, and each branch also curls into a spiral shape. Starch reacts with iodine in color, with linear starch in blue and branched starch in reddish brown
