2. Utangulizi:
N-acetyl-l-cysteine poda ni dutu ya kikaboni na formula ya kemikali C5H9NO3S, poda nyeupe ya fuwele na harufu kama ya vitunguu na ladha ya asidi. Ni mseto, mumunyifu kwa urahisi katika maji au ethanol, isiyoingiliana katika ether na chloroform. Ni tindikali katika suluhisho la maji (PH2-2.75 katika 10g/L H2O), MP101-107 ℃.
Ni N-acetylated derivative ya cysteine, ambayo ina kikundi cha sulfhydryl katika molekuli, ambayo inaweza kuvunja dhamana ya disulfide (-SS-) ya dhamana ya peptide ya mucin, na hivyo kugeuza mnyororo wa mucin kuwa mnyororo mdogo wa peptide ya molekuli na kupunguza mnato wa mucin.
3. Kazi:
N-acetyl-l-cysteine (NAC), ambayo ina athari ya nguvu ya mucolytic kwa kuvunja muundo wa mucin, asidi ya kiini, na kubadilisha sehemu za purutum na kamasi zingine za kamasi kutoka kwa viscous hadi nyembamba. Kwa kuongezea, ina athari ya moja kwa moja ya antioxidant kupitia kikundi cha bure cha sulfhydryl (nucleophilic -SH) ambacho huingiliana moja kwa moja na kikundi cha oxidation cha electrophile.
Bioreagent, API, kikundi cha sulfhydryl (-SH) kilichomo ndani ya molekuli huvunja mnyororo wa disulfide (-SS) unaounganisha mnyororo wa peptide wa mucin katika mucus sputum. Mucin inakuwa molekuli ndogo za minyororo ya peptide na hupunguza ungo wa sputum; Pia huvunja nyuzi za DNA kwenye sputum ya purulent, kwa hivyo inaweza kufuta sio tu nyeupe mucous sputum lakini pia sputum ya purulent.
Muundo wa Masi ya bidhaa hii hufanya iwe rahisi kupita kwenye membrane ya seli. Katika kiini, bidhaa hutengeneza kuunda L-cysteine, asidi muhimu ya amino kwa muundo wa glutathione (GSH).
4. Maombi:
Inatumika katika masomo ya biochemical na kama dawa ya mucolytic. Inatumika kwa usumbufu wa kupumua unaosababishwa na idadi kubwa ya usumbufu wa sputum ya mucous. Inatumika pia kwa detoxization ya sumu ya acetaminophen.
