2. Kupu Whakataki:
Ko te paura konutai-L-Cysteine he taonga matū me te paura matū ma, he karaihe karaihe ma me te kakara reka me te reka waikawa. Ko te hygroscopic, ngawari te whakarewa i roto i te wai, i te etanol ranei, ka hemo i te eter me te chloroform. He waikawa i roto i te otinga wai (ph2-2.75 i te 10G / L H2O), MP101-107 ℃.
He mea hangai o Cysteine, kei roto i te roopu whanariki i roto i te ngota, ka taea te pakaru i te mekameka mucin ki roto i nga mekameka pepptide iti me te whakaiti i te mucin.
3. Mahi:
N-Acetyl-L-Cysteine (NAC), e kaha ana te Mucolytic kaha na te wawahi i nga waahanga mucin, me te whakarereke i nga waahanga punu o te sputum me te mumura me te mumura me te mumura me te mumura me te mumura me te mumura me te mumura me te mumura me te mumura me te mumura me te mumura me te mumura me te mumura me te mumura me te mumura me te mumura me te mumura me te mumura me te mumura me te mumura i te hakihaki. I tua atu, ka kaha te mahi antioxider i roto i te roopu whanariki koreutu (Nucleophilic -sh) e taunekeneke ana me te roopu miihini hiko.
Bioreagent, API, the sulfhydryl group (-SH) contained within the molecule breaks the disulfide chain (-SS) linking the peptide chain of mucin in mucus sputum. Ko te mucin ka riro i nga ngota iti o nga mekameka peppete me te whakaiti i te huringa o te sputum; Ka pakaru ano hoki nga muka DNA i te punu punu, na reira ka taea te rewa kia kaua e rewa noa iho te sputum mucous ma engari ko te papa pu.
Ko te hanganga hau o tenei hua ka ngawari ki te whakawhiti i te membrane pūtau. I roto i te pūtau, ko nga hua o te hua hei hanga l-Cysteine, he waikawa amino nui mo te whakahiato o te glutatione (GSH).
4. Tono:
Whakamahia i roto i nga rangahau koiora me te tarukino mucolytic. Kei te whakamahia te reira mo te aukati i te manawa o te manawa. I whakamahia ano hoki mo te aukati i te paitini o te actamifeophen.
