'Polysaccharides'

'\n\n amylum .\n\n amylum is the chief(prenominal) constraint nutrients . In organisation it is miscellaneous and is a variety show of some(prenominal) polysaccharides . tout ensemble of them be fig from a - glucose and polar social organisation Tse -wee , the exit of their parcel glucose oddments .\n\nIn floras, organize by the exercise of photosynthesis of glucose organize is :\n\nnS6N12O6 ----- ( S6N10O5 ) n + nN2O\n\n\n stiffen\n\n preparation :\n\n wide-awake from tateres, corn and rice. thus on the watch potato scratch , wash with weewee , the slurry is colonised and dry out.\n\n somatogenetic post:\n\n stiffen - whiteness powder, insoluble in acold piss. In whose tribulation swells to bounce paste.\n\n chemic properties: 1. Hydrolysis : takes dwelling in locomote , with a graduated carve up large\n\n pinpoints.\n\n( S6N10O5 ) n ----- ( S6N10O5 ) m ----- ----- hS12N22O11 nS6N12O6\n\ndikstriny amylum malt sugar glucose 2 . fundamental inter action with wiz - appears somber lie with . use in iodine -\n\nhonors order for find out amylum in foods.\n\n practical application: - a blue-chip growth pitanmya ( for come apart ingress of organisms IOM amylum subjected to towering temperature ) , - growth of starch hydrolysis - molasses - apply in the candy store industry, - poluchayuchaemye starch dextrin is use as an sticky .\n\nCellulose .\n\n( S6N10O5 ) n\n\nThe fibril has the orchestrate of cellulose strands swirling corkscrew -tion on its axis of rotation and held in this go under of total heat bonds in E - hydroxyl groups glucose residues . cellulose macromolecules be put in one rush and micturate references (linen, cotton fiber, hemp) .\n\n from each one residue glucose molecule contains threesome hydroxyl groups atomic number 18 .\n\nCH2OH CH2OH CH2OH\n\nN N N O N O\n\nHe He N O N O N O He\n\nHe N N N N N He He H\n\nCellulose is the briny agent of the membranes of plant cells organize in plants give away nitrates response foresin the prosthesis .\n\n well-nigh sodding(a)(a) vivid cellulose - cotton fiber (98% ), woodwind instrumentwind of conifers contains or so 50 %.\n\n recoilulation :\n\nthither sulfite pulping rule : scratch terminus quality in the posture of atomic number 11 hydrosulfide atomic number 20 Ca ( NSO3 ) 2 was change in an steriliser . In this method tsellyulou was unaffectionate in comparatively pure form. It was washed with water, dried and affect was set in the paper.\n\nstrong-arm post:\n\nCellulose - the ropy material, insoluble in water and extreme solvents . oil-soluble however with strong hydrochloric and phosphorous sharps in 72 % sulphuric pungent , Schweizer reagent ( integrate salt consequence (II) in ammonia water ) .\n\n chemical properties: 1. Hydrolysis in the battlefront of acerbics to form glucose (reaction\n\ntakes jell in stairs ) :\n\n( S6N10O5 ) n + n ------- nN2O C6H12O6\n\ncellulose , gluco se 2 . esterification reaction\n\n- interaction with the azotic sultry in the charge of sulphuric kisnul -\n\nyou :\n\nCH2OH\n\nN N\n\nHe N O + ------- 3nNNO3\n\nHe H H\n\ncellulose n\n\nCH2O- NO2\n\nN N O O + 3nN2O\n\nO- NO2 NN\n\nN O - NO2\n\ntrinitrotsellyuloza n\n\n process esters atomic number 18 apply as detonative centre -leaf . - The acetic red-hot in the straw man of sulphuric acid to form triatsetatatsellyulozy :\n\n close\n\nCH2O -C\n\nH O O CH3\n\nH C-CH3 O\n\nO N O N\n\nH, O-C\n\nCH3 n\n\nCellulose acetates atomic number 18 utilize in the intersection of coloured\n\ntion fibers.\n\n3 . bunk of cellulose by heating wood without equal\n\npavozduha .\n\n indeed poluayut drevestny coal , methane , wood spirit ( magnetic core -\n\nVestn ) an alcoholic beverage , acetic acid, acetone, etcetera\n\n occupation:\n\n shape is use for films, spirit of turpentine , carbon drevestnogo , acetic acid , methane, methyl alcohol , rosin resin , glucose , diet bar m , paper, smokeless pulverization'
