Kodi kufanana ndi kusiyana kotani pakati pa formaldehyde ndi glutaraldehyde monga zinthu zolumikizirana?

Formaldehyde ndi glutaraldehydeZonsezi ndi mankhwala omwe amagwiritsidwa ntchito ngati othandizira kulumikizana m'njira zosiyanasiyana, makamaka m'magawo a zamoyo, chemistry, ndi sayansi ya zinthu. Ngakhale kuti amagwira ntchito zofanana pogwirizanitsa ma biomolecule ndikusunga zitsanzo za zamoyo, ali ndi makhalidwe osiyana a mankhwala, reactivity, poizoni, ndi ntchito.

Kufanana:

Zinthu Zogwirizanitsa: formaldehyde ndiglutaraldehyde ndi aldehydes, kutanthauza kuti ali ndi gulu la carbonyl (-CHO) kumapeto kwa kapangidwe kawo ka mamolekyu. Ntchito yawo yayikulu ndikupanga ma covalent bonds pakati pa magulu ogwira ntchito a ma biomolecule, zomwe zimapangitsa kuti alumikizane. Crosslinking ndi yofunika kwambiri pokhazikitsa kapangidwe ka zitsanzo zamoyo, zomwe zimapangitsa kuti zikhale zolimba komanso zosagwirizana ndi kuwonongeka.

Kugwiritsa Ntchito Mankhwala Okhudza Zamankhwala: Formaldehyde ndi glutaraldehyde zimagwiritsidwa ntchito kwambiri m'munda wa zamankhwala. Amagwiritsidwa ntchito kwambiri pokonza ndi kusunga minofu mu maphunziro a histology ndi pathology. Minofu yolumikizidwa imasunga kapangidwe kake ndipo imatha kukonzedwanso kuti igwiritsidwe ntchito pazinthu zosiyanasiyana zowunikira komanso zowunikira.

Kuletsa Tizilombo Toyambitsa Matenda: Mankhwala onsewa ali ndi mphamvu zopha tizilombo toyambitsa matenda, zomwe zimapangitsa kuti akhale othandiza kwambiri pochiza matenda ophera tizilombo toyambitsa matenda komanso pochiza matenda ophera tizilombo toyambitsa matenda. Amatha kuletsa mabakiteriya, mavairasi, ndi bowa, zomwe zimachepetsa chiopsezo cha kuipitsidwa m'malo ochitira kafukufuku komanso m'zida zachipatala.

Ntchito Zamakampani: Zonse ziwiri formaldehyde ndiglutaraldehydeAmagwiritsidwa ntchito m'mafakitale osiyanasiyana. Amagwiritsidwa ntchito popanga zomatira, ma resin, ndi ma polima, komanso m'mafakitale a zikopa ndi nsalu.

Kusiyana:

Kapangidwe ka Mankhwala: Kusiyana kwakukulu pakati pa formaldehyde ndi glutaraldehyde kuli m'mapangidwe awo a mamolekyu. Formaldehyde (CH2O) ndi aldehyde yosavuta, yopangidwa ndi atomu imodzi ya kaboni, ma atomu awiri a haidrojeni, ndi atomu imodzi ya okosijeni. Koma Glutaraldehyde (C5H8O2), ndi aliphatic aldehyde yovuta kwambiri, yokhala ndi ma atomu asanu a kaboni, ma atomu asanu ndi atatu a haidrojeni, ndi ma atomu awiri a okosijeni.

Kuchitapo Kanthu: Glutaraldehyde nthawi zambiri imakhala yogwira ntchito kwambiri kuposa formaldehyde chifukwa cha unyolo wake wautali wa kaboni. Kupezeka kwa maatomu asanu a kaboni mu glutaraldehyde kumailola kuti igwirizane mtunda wautali pakati pa magulu ogwira ntchito pa mamolekyulu amoyo, zomwe zimapangitsa kuti ilumikizane mwachangu komanso moyenera.

Kugwira Ntchito Mogwirizana: Chifukwa cha mphamvu yake yowonjezereka, glutaraldehyde nthawi zambiri imakhala yothandiza kwambiri polumikizana ndi ma biomolecule akuluakulu, monga mapuloteni ndi ma enzyme. Formaldehyde, ngakhale kuti imatha kulumikizana, ingafunike nthawi yochulukirapo kapena kuchuluka kwakukulu kuti ikwaniritse zotsatira zofanana ndi mamolekyu akuluakulu.

Kuopsa kwa Glutaraldehyde: Glutaraldehyde imadziwika kuti ndi poizoni kwambiri kuposa formaldehyde. Kukhudzana ndi glutaraldehyde kwa nthawi yayitali kapena kwambiri kungayambitse kuyabwa pakhungu ndi kupuma, ndipo imaonedwa kuti ndi yothandiza kwambiri, zomwe zikutanthauza kuti ingayambitse ziwengo mwa anthu ena. Mosiyana ndi zimenezi, formaldehyde ndi khansa yodziwika bwino ndipo imabweretsa mavuto pa thanzi, makamaka ikapumidwa kapena ikakhudzana ndi khungu.

Kugwiritsa Ntchito: Ngakhale kuti mankhwala onsewa amagwiritsidwa ntchito pomanga minofu, nthawi zambiri amagwiritsidwa ntchito pazifukwa zosiyanasiyana. Formaldehyde imagwiritsidwa ntchito nthawi zambiri pa ntchito za histological ndi embalming, pomwe glutaraldehyde ndi yoyenera kwambiri kusunga kapangidwe ka maselo ndi malo a antigenic mu maphunziro a electron microscopy ndi immunohistochemical.

Kukhazikika: Formaldehyde ndi yosinthasintha ndipo imakonda kusungunuka mofulumira kuposa glutaraldehyde. Kapangidwe kameneka kangakhudze momwe zinthu zolumikizirana zimagwirira ntchito komanso momwe zimasungidwira.

Mwachidule, formaldehyde ndi glutaraldehyde zimafanana ndi zinthu zomwe zimagwirizanitsa zinthu, koma zimasiyana kwambiri mu kapangidwe ka mankhwala, momwe zimagwirira ntchito, poizoni, ndi momwe zimagwiritsidwira ntchito. Kumvetsetsa bwino kusiyana kumeneku ndikofunikira posankha chinthu choyenera chogwirizanitsa zinthu pazifukwa zinazake ndikuwonetsetsa kuti chikugwiritsidwa ntchito bwino m'malo osiyanasiyana asayansi, azachipatala, komanso mafakitale.
