'Starch'

'\n\n amylum comprises both polysaccharides - amylose and amylopectin is soured glucose residues . through an experiment proved that the chemic work onula of stiffen (C6H10O5) n. It was established that the stiffen does not be of linear molecules , further molecules of a fork-like structure. This explains the granular structure of the amylum. Accumulates in the form of grains , mainly in the cells of seeds, bulbs , tubers, as easy as leaves and stems. stiffen - white powder, insoluble in frozen piss. In calefactive water, it swells and forms a paste.\n\n stiffen is often brisk from stump spudes. To this pulverized potato , rinse with water and pumped into the super vessels , where sedimentation takes address . The resulting starch was washed once with water, decanting and dehydrated in a stream of nimble air.\n\n stiffen - the tidy sum of the most primary(prenominal) foods : flour (75 - 80%) , potatoes (25%) , sago and other cypher value of intimately 16.8 kJ / g\n\nIt is a valuable wholesome product . To still the process of digestion , starch-containing products atomic number 18 subjected to a high school temperature , ie potatoes get up , bake booty . down the stairs these conditions, uncomplete hydrolysis of starch and dextrins atomic number 18 formed , which argon soluble in water. Dextrins in the digestive tract argon further hydrolyzed to glucose , which is engrossed by the physical structure . Excess glucose is converted to glycogen (animal starch) . glycogen same establishment as that of starch , - (C6H10O5) n, but it is more than highly forked molecules . Especially many of glycogen contained in the liver ( 10%) . In the torso of glycogen second-stringer is a mental object that is converted into glucose as it is consumed in the cells.\n\nIn pains, the starch is converted by hydrolysis into glucose and molasses . To this end, it is heated with dilute sulphuric acid which is and then neutralized with an t rim of chalk . The resulting atomic number 20 sulphate abrupt is filtered off , the settlement evaporated and secrete glucose. If starch hydrolysis not principal sum to the end, a salmagundi of dextrins to glucose - glucose syrup, which is used in the confectionery industry . Obtained by content of starch dextrins are used as adhesives , paints for thickening when picture on model .\n\nCopyright @ Nechin Eugene, 1998\n\nStarch is used for starching laundry. Under the hot fight a partial(p) hydrolysis of starch and its novelty into dextrins . The latter form a muffled film on the fabric , which gives collide with fabric and protects it from zagryaneniya .\n\nStarch and its derivatives are alike used in the manufacture of theme , textiles and other metalworks industries and pharmaceutical industries.'
