Qhov sib txawv tseem ceeb ntawm zwitterion thiab dipole yog zwitterion yog qhov nruab nrab molecule uas muaj cov hluav taws xob sab hauv, hos dipole yog qhov muaj qhov zoo thiab qhov tsis zoo them xaus lossis sab qaum teb thiab sab qab teb sib nqus ncej.
Cov ntsiab lus zwitterion thiab dipole muaj feem cuam tshuam rau ib leeg raws li muaj ob qhov xwm txheej sib txawv hauv tib lub cev. Piv txwv li, zwitterions muaj cov nqi zoo thiab tsis zoo nyob rau hauv tib lub molecule, thaum hluav taws xob dipole muaj qhov zoo thiab qhov tsis zoo them tag rau tib qhov hluav taws xob.
Zwitterion yog dab tsi?
Zwitterion, los yog cov ntsev sab hauv, yog ib qho molecule uas muaj qhov sib npaug ntawm cov pab pawg ua haujlwm zoo thiab tsis zoo. Hauv lwm lo lus, zwitterion muaj ob pawg cationic thiab anionic nyob rau hauv tib lub molecule nyob rau hauv sib npaug. Lub sij hawm zwitterion tsuas yog los nrog cov amino acids, tab sis nws kuj yog siv nrog sulfamic acid molecules, anthranilic acid, thiab EDTA protonation.
Piv txwv li, cov amino acids hauv cov tshuaj aqueous tsim cov tshuaj sib npaug ntawm niam txiv amino acid molecule thiab zwitterion. Cov tshuaj sib npaug no tsim los ntawm ob kauj ruam. Nyob rau hauv thawj kauj ruam, ib tug proton yog hloov los ntawm cov carboxyl pawg ntawm cov amino acid molecule mus rau ib tug dej molecule, tsim hydronium ion thiab cov tshuaj tsis zoo nqi ntawm cov amino acid. Tom qab ntawd, nyob rau hauv lub thib ob kauj ruam, ib tug proton yog pauv los ntawm hydronium ion mus rau amine pawg ntawm tib amino acid molecule, tam sim no muaj ib tug tsis zoo nqi. Qhov no tsim ib qho txiaj ntsig zoo ntawm pawg amine thaum muaj qhov tsis zoo ntawm pawg carboxyl. Yog li ntawd, cov tshuaj tiv thaiv isomerization tshwm sim, tsim ib zwitterion.
Daim duab 01: Kev tsim ntawm Zwitterion hauv cov tshuaj muaj Amino Acid Molecules
Feem ntau, nws tsis tuaj yeem kawm qhov sib npaug ntawm qhov sib xyaw thiab nws cov zwitterion sim. Txawm li cas los xij, peb tuaj yeem tau txais qee qhov kev nkag siab siv keeb kwm yav dhau los.
Dipole yog dab tsi?
Lo lus dipole yog hais txog hluav taws xob lossis sib nqus dipole uas siv hauv electromagnetism. Cov hluav taws xob dipoles cuam tshuam nrog kev sib cais ntawm cov nqi sib txawv (cov nqi zoo thiab tsis zoo) hauv txhua lub tshuab hluav taws xob. E.g. ib khub ntawm cov nqi hluav taws xob uas muaj qhov sib npaug ntawm qhov sib npaug thiab cov cim qhia tus nqi sib txawv thiab sib cais los ntawm qhov deb me me. Nyob rau hauv lub magnetic dipole, peb tuaj yeem soj ntsuam qhov kev kaw ntawm qhov hluav taws xob tam sim no.
Daim duab 02: Dipole
Txawm tias nws yog hluav taws xob dipole lossis magnetic dipole, peb tuaj yeem ua tus yam ntxwv ntawm lub sijhawm dipole. Dipole lub sij hawm yog vector kom muaj nuj nqis. Nyob rau hauv ib qho yooj yim hluav taws xob dipole, lub sij hawm dipole coj los ntawm tus nqi tsis zoo rau tus nqi zoo. Qhov loj ntawm lub sijhawm dipole no yog sib npaug ntawm lub zog ntawm txhua tus nqi no, lub sijhawm sib cais ntawm cov nqi no. Ib yam li ntawd, muaj lub sijhawm sib nqus dipole rau magnetic dipoles uas taw qhia los ntawm lub voj voog tam sim no. Nws muaj qhov loj me uas sib npaug rau qhov tam sim no hauv lub voj voog lub sijhawm ntawm thaj tsam ntawm lub voj.
Ntxiv mus, tuaj yeem muaj qee qhov kev faib tawm rau dipoles; Piv txwv li, muaj ib lub cev dipole uas muaj ob qhov sib npaug thiab qhov sib npaug; point dipole yog qhov txwv uas peb tuaj yeem tau txais los ntawm kev cia qhov kev sib cais ua xoom thaum khaws lub sijhawm tam sim dipole, thiab lwm yam.
Qhov txawv ntawm Zwitterion thiab Dipole yog dab tsi?
Cov ntsiab lus zwitterion thiab dipole muaj feem cuam tshuam rau ib leeg raws li muaj ob qhov xwm txheej sib txawv hauv tib lub cev. Txawm li cas los xij, qhov sib txawv tseem ceeb ntawm zwitterion thiab dipole yog zwitterion yog ib qho nruab nrab molecule uas muaj hluav taws xob sab hauv, hos dipole yog qhov muaj qhov zoo thiab tsis zoo them xaus lossis sab qaum teb thiab sab qab teb sib nqus ncej.
Cov lus hauv qab no nthuav tawm qhov sib txawv ntawm zwitterion thiab dipole kom meej.
Summary – Zwitterion vs Dipole
Cov ntsiab lus zwitterion thiab dipole muaj feem cuam tshuam rau ib leeg raws li muaj ob qhov xwm txheej sib txawv hauv tib lub cev. Qhov sib txawv tseem ceeb ntawm zwitterion thiab dipole yog tias zwitterion yog ib qho nruab nrab molecule uas muaj cov hluav taws xob sab hauv qhov twg dipole yog qhov muaj qhov zoo thiab tsis zoo them xaus lossis sab qaum teb thiab sab qab teb sib nqus ncej.
