Txawm hais tias lawv ua haujlwm zoo sib xws hauv kev sib txuas biomolecules thiab khaws cov qauv tshuaj lom neeg, lawv muaj cov khoom siv tshuaj sib txawv, kev ua haujlwm, kev lom, thiab kev siv.
Kev Zoo Sib Xws:
Cov Neeg Sawv Cev Crosslinking: Ob qho tib si formaldehyde thiabglutaraldehyde yog cov aldehyde, txhais tau tias lawv muaj ib pawg carbonyl (-CHO) nyob rau thaum kawg ntawm lawv cov qauv molecular. Lawv lub luag haujlwm tseem ceeb yog los tsim cov kev sib txuas ntawm cov pab pawg ua haujlwm ntawm biomolecules, ua rau muaj kev sib txuas. Kev sib txuas yog qhov tseem ceeb rau kev ruaj khov ntawm cov qauv ntawm cov qauv biological, ua rau lawv muaj zog dua thiab tiv taus kev puas tsuaj.
Kev Siv Biomedical: Ob qho tib si formaldehyde thiab glutaraldehyde pom muaj kev siv ntau hauv kev kho mob biomedical. Lawv feem ntau siv rau kev kho thiab khaws cov ntaub so ntswg hauv kev tshawb fawb txog histology thiab pathology. Cov ntaub so ntswg sib txuas ua ke tswj lawv cov qauv thiab tuaj yeem ua tiav ntxiv rau ntau yam kev tshuaj xyuas thiab kev kuaj mob.
Kev Tswj Kab Mob Me Me: Ob yam tshuaj no muaj cov tshuaj tua kab mob, ua rau lawv muaj txiaj ntsig zoo rau kev tua kab mob thiab kev ua kom tsis muaj kab mob. Lawv tuaj yeem tua cov kab mob me me, cov kab mob me me, thiab cov pwm, txo qhov kev pheej hmoo ntawm kev ua qias tuaj hauv chaw kuaj mob thiab cov khoom siv kho mob.
Daim Ntawv Thov Kev Lag Luam: Ob qho tib si formaldehyde thiabglutaraldehydesiv rau hauv ntau yam kev lag luam. Lawv siv rau hauv kev tsim cov nplaum, cov resins, thiab cov polymers, nrog rau hauv kev lag luam tawv thiab textile.
Qhov txawv:
Cov Qauv Tshuaj: Qhov sib txawv tseem ceeb ntawm formaldehyde thiab glutaraldehyde yog nyob rau hauv lawv cov qauv molecular. Formaldehyde (CH2O) yog qhov aldehyde yooj yim tshaj plaws, muaj ib lub carbon atom, ob lub hydrogen atoms, thiab ib lub oxygen atom. Glutaraldehyde (C5H8O2), ntawm qhov tod tes, yog ib qho aliphatic aldehyde nyuaj dua, muaj tsib lub carbon atoms, yim lub hydrogen atoms, thiab ob lub oxygen atoms.
Kev Ua Haujlwm: Glutaraldehyde feem ntau muaj kev ua haujlwm ntau dua li formaldehyde vim nws cov saw hlau ntev dua. Qhov muaj tsib lub carbon atoms hauv glutaraldehyde tso cai rau nws txuas cov kev ncua deb ntev dua ntawm cov pab pawg ua haujlwm ntawm biomolecules, ua rau kev sib txuas sai dua thiab ua haujlwm tau zoo dua.
Kev Ua Haujlwm Zoo ntawm Kev Sib Txuas: Vim nws muaj zog dua, glutaraldehyde feem ntau ua haujlwm tau zoo dua ntawm kev sib txuas cov biomolecules loj dua, xws li cov protein thiab cov enzymes. Formaldehyde, thaum tseem muaj peev xwm sib txuas, tej zaum yuav xav tau ntau lub sijhawm lossis ntau dua kom ua tiav cov txiaj ntsig zoo sib xws nrog cov molecules loj dua.
Kev Lom: Glutaraldehyde paub tias muaj tshuaj lom ntau dua li formaldehyde. Kev raug glutaraldehyde ntev lossis ntau dhau tuaj yeem ua rau tawv nqaij thiab ua pa tsis zoo, thiab nws suav tias yog ib qho ua rau khaus, txhais tau tias nws tuaj yeem ua rau qee tus neeg ua xua. Qhov sib txawv, formaldehyde yog ib qho carcinogen paub zoo thiab ua rau muaj kev pheej hmoo rau kev noj qab haus huv, tshwj xeeb tshaj yog thaum nqus pa lossis kov daim tawv nqaij.
Daim Ntawv Thov: Txawm hais tias ob qho tshuaj no siv rau hauv kev kho cov ntaub so ntswg, lawv feem ntau nyiam rau ntau lub hom phiaj sib txawv. Formaldehyde feem ntau siv rau kev siv histological niaj hnub thiab embalming, thaum glutaraldehyde yog qhov tsim nyog dua rau kev khaws cov qauv cellular thiab cov chaw antigenic hauv electron microscopy thiab immunohistochemical kev tshawb fawb.
Kev Ruaj Ntseg: Formaldehyde yog cov khoom uas yaj sai dua thiab feem ntau yuav yaj sai dua li glutaraldehyde. Cov yam ntxwv no tuaj yeem cuam tshuam rau kev tuav thiab khaws cia ntawm cov neeg sawv cev crosslinking.
Hauv kev xaus, formaldehyde thiab glutaraldehyde muaj cov yam ntxwv zoo sib xws ua cov neeg sawv cev sib txuas, tab sis lawv txawv ntau hauv lawv cov qauv tshuaj lom neeg, kev ua haujlwm, kev lom, thiab kev siv. Kev nkag siab zoo txog cov kev sib txawv no yog qhov tseem ceeb rau kev xaiv tus neeg sawv cev sib txuas tsim nyog rau cov hom phiaj tshwj xeeb thiab xyuas kom muaj kev nyab xeeb thiab siv tau zoo hauv ntau yam kev tshawb fawb, kev kho mob, thiab kev lag luam.
