Starch is a high polymer of glucose , Qianfen known in the catering industry , the general formula (C6H10O5) n, hydrolysis of the disaccharide maltose stage , the chemical formula (C12H22O11), obtained after complete hydrolysis of glucose , chemical formula (C6H12O6). There starch amylose and amylopectin categories. Starch is the storage of nutrients in plants , seeds and tubers stored in , the types of plants have a high content of starch .
Starch (amylum) is a polysaccharide . Starch manufacture is a form of energy storage plants . Formula (C6H10O5) n.
Amylose starch can be divided into ( amylose ) and amylopectin ( starch glue ) . The former is no branch of the helical structure ; the latter 24 to 30 glucose residues in α-1, 4 - glycosidic bond connected to each other , at the office of branched-chain α-1, 6 - glycosidic bond .
Amylose case of iodine was blue, iodine amylopectin was purple . This is not a starch undergoes a chemical reaction with iodine (reaction), but from the interaction (interaction), but starch screw hole just big enough for the central iodine molecules through van der Waals forces , the two form a blue- black malocclusion thereof. Experimental results show that the iodine molecules can not separate the starch blue , in fact, a blue starch iodine ions (I3).
