Tib neeg kuj nug, dab tsi yog cov khoom ntawm sucrose zoo li?
Ntshiab sucrose feem ntau yog npaj raws li ib qho zoo, tsis muaj xim, tsis muaj ntxhiab tsw crystalline hmoov nrog lub siab nyiam, qab zib saj. Sucrose melts thiab decomposes ntawm 186 ° C los tsim caramel, thiab thaum combusted tsim carbon, carbon dioxide, thiab dej.
Tsis tas li ntawd, piv txwv ntawm cov khoom siv tshuaj lom neeg yog dab tsi? Piv txwv ntawm cov khoom siv tshuaj muaj xws li flammability, toxicity, acidity, reactivity (ntau hom), thiab kub ntawm combustion. Hlau, piv txwv li, ua ke nrog oxygen nyob rau hauv lub xub ntiag ntawm dej los ua xeb; chromium tsis oxidize (Daim duab 2).
Hais txog qhov no, dab tsi yog qhov muaj pes tsawg leeg ntawm sucrose?
Sucrose yog qhov ntau qab zib . Nws yog ib tug disaccharide, ib tug molecule muaj li ntawm ob monosaccharides: qabzib thiab fructose. Sucrose yog tsim nyob rau hauv cov nroj tsuag, los ntawm lub rooj twg qab zib yog refined. Nws muaj cov qauv molecular C12H22O11.
Dab tsi ua haujlwm pab pawg muaj nyob hauv sucrose?
Sucrose muaj cov tshuaj formula C12H22O11. Nws muaj 8 pawg hydroxyl thiab peb acetals.

Nws yog qee zaum hu ua huab cua sab hnub poob ntug dej hiav txwv lossis dej hiav txwv huab cua
Cov yam ntxwv ntawm cov ntaub ntawv twg yog qhov ntsuas ntawm tus nqi uas cov ntaub ntawv muaj nuj nqis heev?
Variation: Ib qho kev ntsuas ntawm tus nqi uas cov ntaub ntawv muaj nuj nqis sib txawv. ? Kev faib tawm: Cov xwm txheej lossis cov duab ntawm kev sib kis ntawm cov ntaub ntawv hla ntau qhov tseem ceeb (xws li tswb-puab). ? Outliers: Cov qauv piv txwv uas nyob deb heev ntawm feem ntau ntawm lwm cov qauv nqi
Qhov twg ntawm cov no yog tus yam ntxwv ntawm txhua yam muaj sia?
Cov yam ntxwv no yog lub koom haum ntawm tes, kev yug me nyuam, metabolism, homeostasis, heredity, teb rau stimuli, kev loj hlob thiab kev loj hlob, thiab adaptation los ntawm evolution. Qee yam, xws li tus kab mob, pom tsuas yog qee yam ntawm cov yam ntxwv no thiab yog li ntawd, tsis muaj sia nyob
Dab tsi ntawm lub cev nta yog cov yam ntxwv ntawm cov ntug dej hiav txwv ntawm Texas?
Texas 'Gulf Coastal Plains yog sab hnub poob txuas ntxiv ntawm ntug hiav txwv tiaj tiaj txuas los ntawm Dej Hiav Txwv Atlantic mus dhau Rio Grande. Nws cov yam ntxwv dov mus rau toj roob hauv pes npog nrog kev loj hlob hnyav ntawm ntoo thuv thiab tawv ntoo txuas mus rau East Texas
