Qhov Tseem Ceeb Qhov txawv - Acrylamide vs Bisacrylamide

Raws li ob lub npe acrylamide thiab bisacrylamide suab zoo ib yam, lawv cov qauv tshuaj kuj muaj qee qhov zoo sib xws. Ib qho Bisacrylamide molecule muaj ob lub acrylamide molecule koom nrog -CH₂- choj ntawm Nitrogen atom hauv pawg amide. Qhov txuas no yog tsim los ntawm kev tshem tawm ib qho atom hydrogen thiab tom qab ntawd txuas rau cov pa roj carbon atom hauv CH ₂ pawg. Ob qho tib si ntawm cov tebchaw no yog kev lag luam tseem ceeb heev thiab siv rau ntau yam kev siv. Kev sib xyaw ntawm ob lub tebchaw no yog siv rau hauv qee qhov kev siv. Qhov sib txawv tseem ceeb ntawm Acrylamide thiab Bisacrylamide yog cov tshuaj formula ntawm Acrylamide yog C₃H₅NO whereas cov tshuaj formula ntawm Bisacrylamide yog C ₇H₁₀N₂O₂

YAcrylamide yog dab tsi?

IUPAC lub npe ntawm acrylamide yog prop-2-enamide, thiab nws cov tshuaj formula yog C₃H₅NO. Nws tseem hu ua acrylic amide. Acrylamide yog ib qho tsis muaj ntxhiab tsw, dawb crystalline khoom. Nws yog soluble hauv qee cov kuab tshuaj xws li dej, ethanol, ether, thiab chloroform. Nws decomposes thaum acids, bases, oxidizing agents, hlau thiab hlau ntsev nyob rau hauv nruab nrab. Thaum lub decomposition tshwm sim tsis-thermally, nws tsim ammonia (NH ₃), thiab cov thermal decomposition ua carbon monoxide (CO), carbon dioxide (CO _{2) thiab oxides ntawm nitrogen.}

Tshuaj Cov Qauv ntawm Acrylamide

Bisacrylamide yog dab tsi?

Bisacrylamide tseem hu ua N, N'-Methylenebisacrylamide (MBAm lossis MBAA) thiab nws cov mis molecular yog C₇H₁₀N ₂O_{2Nws yog tus neeg sawv cev sib txuas uas siv los tsim cov polymers xws li polyacrylamide. Nws kuj tseem siv rau hauv biochemistry vim nws yog ib qho ntawm cov khoom sib txuas ntawm polyacrylamide gel. Nws tuaj yeem ua polymerize nrog acrylamide, thiab tsim kev sib txuas ntawm cov saw hlau polyacrylamide, tsim ib lub network ntawm polyacrylamide es tsis txuas cov kab sib txuas ntawm polyacrylamide.}

Tshuaj Txheej Txheem ntawm Bisacrylamide

Qhov txawv ntawm Acrylamide thiab Bisacrylamide yog dab tsi?

yam ntxwv ntawm Acrylamide thiab Bisacrylamide

qauv:

Acrylamide: Cov mis molecular ntawm acrylamide yog C_3H5_{NO, thiab nws cov qauv tshuaj yog raws li qhia saum toj no.}

Bisacrylamide: Cov mis molecular ntawm bisacrylamide yog C₇H₁₀N₂O _{2,thiab nws cov qauv yog raws li qhia saum toj no.}

Siv:

Acrylamide: Acrylamide yog cov tshuaj siv nyob rau hauv qee qhov kev lag luam tseem ceeb xws li kev tsim cov ntawv, yas, thiab cov xim dyes. Nws kuj tseem siv rau hauv cov chaw kho dej los kho cov dej haus thiab dej khib nyiab. Ib qho me me ntawm acrylamide yog siv los tsim qee cov khoom siv xws li cov khoom ntim khoom noj, thiab qee cov nplaum.

Bisacrylamide: Bisacrylamide yog siv rau hauv cov ntawv thov microbiological; nws tuaj yeem hloov kho rau hauv cov polymers tshiab thiab cov tebchaw uas muaj cov tshuaj tua kab mob. Tsis tas li ntawd, nws yog siv los tsim polyacrylamide gel hauv electrophoresis gels. Nws tsim kev sib txuas ntawm acrylamide thiab bis-acrylamide. Qhov sib piv ntawm acrylamide thiab polyacrylamide txiav txim siab cov yam ntxwv ntawm polyacrylamide gel. Nws tuaj yeem tuav lub firmness ntawm gel; vim nws muaj peev xwm los tsim ib lub network es tsis yog linear chains.

Abundance:

Acrylamide: Txawm hais tias Acrylamide tau muaj nyob hauv cov zaub mov txij li thaum pib ua noj, nws tau pom thawj zaug hauv cov zaub mov hauv xyoo 2002 (Lub Plaub Hlis).

Acrylamide ib txwm ua hauv cov khoom noj khoom haus starchy ntawm kev ua noj kub kub (ntawm 120 ^{othiab noo noo tsawg); xws li kib, ci thiab ci. Qhov no tshwm sim vim muaj tshuaj lom neeg hu ua "Maillard cov tshuaj tiv thaiv" uas 'xim av' cov zaub mov thiab cuam tshuam rau nws saj.}

Nws tuaj yeem tsim los ntawm cov suab thaj thiab cov amino acids (tsuas yog hauv asparagine) uas muaj nyob hauv ntau cov khoom noj. Tsis tas li ntawd, acrylamide muaj nyob rau hauv qos yaj ywm crisps, Fabkis fries, biscuits, qhob cij, thiab kas fes. Tab sis, nws tsis tshwm sim hauv ntim khoom noj lossis hauv ib puag ncig. Ntxiv mus, nws kuj pom muaj nyob rau hauv cov khoom tsis yog khoom noj xws li haus luam yeeb.

Bisacrylamide: Bisacrylamide yog ib qho kev lag luam muaj crosslinker siv nrog acrylamide uas muaj nyob rau hauv cov hmoov qhuav thiab cov tshuaj tov ua ntej.
