Ntchito & Kugwiritsa ntchito N-Acetyl-L-Cysteine (Ac-Cys-OH; NAC) (CAS: 616-91-1) ufa
1. N-Acetyl-L-Cysteine, yomwe imadziwikanso kuti N-Acetylcysteine kapena Acetylcysteine (NAC), ndi mankhwala osokoneza bongo komanso zakudya zowonjezera zomwe zimagwiritsidwa ntchito makamaka ngati mucolytic agent komanso poyang'anira paracetamol (acetaminophen) overdose.Ntchito zina zimaphatikizapo kubwezeretsanso sulphate muzochitika, monga autism, kumene cysteine ndi ma amino acid okhudzana ndi sulfure akhoza kutha.
2. N-Acetyl-L-Cysteine ndi yochokera ku cysteine pomwe gulu la acetyl limamangiriridwa ku atomu ya nayitrogeni.Chigawochi chimagulitsidwa ngati chowonjezera chazakudya chomwe chimati ndi antioxidant komanso chitetezo cha chiwindi.Amagwiritsidwa ntchito ngati mankhwala a chifuwa chifukwa amathyola zomangira za disulfide mu ntchofu ndikuzisungunula, zomwe zimapangitsa kukhala kosavuta kutsokomola.Ndikuchitanso uku kuswa maubwenzi a disulfide komwe kumapangitsa kukhala kothandiza pakupatulira ntchofu wokhuthala mwa odwala cystic ndi pulmonary fibrosis.
3. Acetylcysteine ndi mucolytic wothandizira ndi mphamvu mucolytic kwenikweni.Gulu la sulfhydryl lomwe lili mu molekyulu limatha kuswa mgwirizano wa disulfide mu unyolo wa glycoprotein polypeptide mu sputum, potero kuchepetsa kukhuthala kwa sputum, ndikupanga sputum kukhala madzi komanso kutsokomola kosavuta.Mankhwalawa amathanso kuthyola ulusi wa DNA mu purulent sputum, kotero kuti sangathe kusungunula sputum woyera, komanso sputum ya purulent.Kwa odwala omwe expectorants ambiri sagwira ntchito, mankhwalawa amatha kukhala othandiza.
4. Amagwiritsidwa ntchito ngati mankhwala osungunula phlegm.Amagwiritsidwa ntchito pofufuza zamankhwala ndi zamankhwala ngati mankhwala a phlegm ndi acetaminophen poisoning.Zamoyo zamchere reagent, mankhwala, mankhwalawa ntchito monga expectorant, anati phlegm n'zosavuta kuyeretsa.
5. Zomwe zimachitika kawirikawiri ndi nseru ndi kusanza pamene watengedwa pakamwa. Khungu nthawi zina limakhala lofiira ndi kuyabwa ndi mawonekedwe aliwonse.Mtundu wopanda chitetezo cha mthupi wa anaphylaxis ukhozanso kuchitika.Zikuwoneka kuti ndizotetezeka pa mimba.Pakuchuluka kwa paracetamol, imagwira ntchito powonjezera kuchuluka kwa glutathione, antioxidant yomwe imatha kusokoneza zinthu zowononga za paracetamol.Akakowetsedwa, amakhala ngati mucolytic pochepetsa makulidwe a ntchofu.
6. Acetylcysteine inayamba kugwiritsidwa ntchito mu 1960 ndipo inayamba kugwiritsidwa ntchito pachipatala mu 1968. Ili pa List of Essential Medicines la World Health Organization, yomwe imatchula mankhwala otetezeka komanso ogwira mtima kwambiri omwe amafunikira pachipatala.Amapezeka ngati mankhwala anthawi zonse ndipo ndi otsika mtengo.
7. N-Acetyl-L-Cysteine ndi mtundu wa acetylated wa L-cysteine omwe amatengedwa bwino ndikugwiritsidwa ntchito.Ndi antioxidant yomwe imathandiza polimbana ndi ma virus.N-Acetyl-l-Cysteine yakhala ikugwiritsidwa ntchito ngati chitetezo cha chiwindi ndikuthyola ntchofu za m'mapapo ndi bronchial.
8. N-Acetyl-L-Cysteine ikhoza kulimbikitsa milingo ya glutathione m'maselo.
9. N-Acetyl-L-Cysteine ndi amino acid wofunikira, imodzi mwa ma amino acid atatu okhala ndi sulfure, enawo ndi taurine (omwe amatha kupangidwa kuchokera ku L-cysteine) ndi L-methionine momwe L-cysteine ingangathekere. kupangidwa m'thupi ndi njira zambiri.
10. N-Acetyl-L-Cysteine ikhoza kukhala ngati antioxidant, ingateteze matenda a chiwindi, ndipo ingathandize kulimbitsa ma diameter a tsitsi omwe alipo ngati atengedwa nthawi zonse.
11. Kugwiritsa ntchito m'madera azachipatala Monga wothandizira kupuma, angagwiritsidwe ntchito ngati mankhwala osungunula ng'oma za phlegm.imatha kuchiza matenda a bronchitis.Komanso, N-Acetyl-L-Cysteine ingagwiritsidwe ntchito ngati mankhwala pamene acetaminophen poizoni.
12. Kugwiritsa ntchito m'minda yodzikongoletsera N-Acetyl-L-Cysteine kumakhala ndi zotsatira zabwino pakuchotsa ma radicals opanda okosijeni ndi ma oxides ena ndikuchepetsa ukalamba, kumathanso kusokoneza kupanga kwa melanin, komanso kumathandiza kuthetsa mawanga pakhungu.
13. Kugwiritsa ntchito chakudya cha ziweto N-Acetyl-L-Cysteine itha kugwiritsidwa ntchito ngati chowonjezera cha chakudya.
14. Zodzoladzola makamaka ntchito kukongola madzi, perm madzimadzi, dzuwa proof khungu chisamaliro kirimu.Lili ndi ntchito yoletsa kukalamba kwachilengedwe.N-Acetyl-l-Cysteine imatha kuteteza ndikuchiza kuvulala kwa radiation.N-acetyl Cysteine imatha kuchotsa khungu la melanin palokha, kusintha chikhalidwe cha khungu lokha, khungu limakhala loyera lachilengedwe.Ndi mtundu wa zodzoladzola zoyera zoyera.
15. Zakudya zowonjezera.Ntchito mkate, kulimbikitsa mapangidwe gilateni ndi kulimbikitsa nayonso mphamvu, nkhungu, kupewa ukalamba.Amagwiritsidwa ntchito mu timadziti tachilengedwe kuti ateteze vitamini C kuti asakhudzidwe ndi okosijeni komanso kuteteza timadziti kuti zisanduke bulauni.
