Cov lus piav qhia ntawm N-Acetyl-L-cysteine
N-Acetyl-L-cysteine yog N-acetyl derivative ntawm cov amino acid Lcysteine, thiab yog ib tug precursor nyob rau hauv tsim cov antioxidant glutathione nyob rau hauv lub cev. thiol (sulfhydryl) pab pawg muaj cov teebmeem antioxidant thiab tuaj yeem txo cov dawb radicals. Cov tshuaj no yog muag raws li kev noj haus ntxiv uas feem ntau thov cov tshuaj antioxidant thiab lub siab tiv thaiv cov teebmeem. Nws yog siv los ua tshuaj hnoos vim tias nws rhuav tshem cov disulfide bonds hauv cov hnoos qeev thiab liquefies nws, ua rau nws yooj yim rau hnoos. Nws tseem yog qhov kev txiav txim ntawm kev rhuav tshem cov ntawv cog lus disulfide uas ua rau nws muaj txiaj ntsig hauv kev ua kom nyias nyias nyias nyias nyias hauv cov neeg mob cystic thiab pulmonary fibrosis.
N-Acetyl cysteine yog ib qho amino acid, tuaj yeem hloov pauv ntawm lub cev ntawm methionine, cystine tuaj yeem hloov nrog ib leeg. N-Acetyl-l-cysteine tuaj yeem siv los ua cov tshuaj mucilagenic. Nws yog qhov tsim nyog rau kev ua pa ua pa los ntawm qhov ntau ntawm phlegm obstruction. Tsis tas li ntawd, nws tseem tuaj yeem siv rau kev tshem tawm cov tshuaj acetaminophen lom.
Cov txiaj ntsig ntawm N-acetyl-l-cysteine
N-acetyl-l-cysteine yog cov tawv nqaij txias. Nws kuj tseem siv tau los ua cov khoom siv los tiv thaiv kev laus uas tau muab lub peev xwm los tswj cov tawv nqaij atrophy thiab txo cov tsos ntawm cov kab zoo thiab wrinkles.
N-acetyl-l-cysteine (NAC) yog derivative ntawm kev noj haus amino acid l-cysteine. NAC muaj kev sib raug zoo rau lub ntsws cov ntaub so ntswg, uas nws txhawb los ntawm mucolytic thiab antioxidant kev ua. NAC tseem txhim kho glutathione ntau lawm thiab ua lub luag haujlwm hauv cov hlau hnyav detoxification.
