I-White Crystalline N-acetyl-l-cysteine Impushana

1 . Imininingwane eyisisekelo :

Product Name	N-Acetyl-L-cysteine
Specification	98%
Appearance	White crystalline powder
CAS NO.	616-91-1
Molecular formula	C5H9NO3S
Molecular weight	163.19
EINECS no.	210-498-3
Melting point	106-108 ° C (lit.)
Specific rotation	35.1ºC(c=2,H2O)
Boiling point	407.7 + / - 40.0 ° C (Predicted)
Solubility	Soluble in water, ethanol, methanol, dimethyl sulfoxide, hot isopropyl alcohol, methyl acetate and ethyl acetate. Insoluble in chloroform and ether.

2. Isingeniso:

I-N-acetyl-L-Cysteine powder iyinto e-organic ngefomula yamakhemikhali C5h9NO3s, i-crystalline powder emhlophe enephunga elinjengegalikhi kanye nokunambitheka kwe-acidic. Kuyi-hygroscopic, ukuncibilika kalula emanzini noma i-ethanol, infoluble ku-ether ne-chloroform. Kuyi-acidic kwisixazululo samanzi (Ph2-2.75 ku-10G / L H2O), MP101-107 ℃.

Kungu-N-actedEated derivative of Cysteine, okuqukethe iqembu leSulfydryl ku-molecule, elingase libhidlize isibopho se-mucin peptide, ngaleyo ndlela siguqule iketanga elincane le-molecule clectide.

3. Umsebenzi:

I-N-acetyl-L-Cysteine (NAC), enamandla aqinile mucolytic umphumela ngokuphula izakhiwo ze-mucin, ama-acid ama-nucleic, kanye nokushintsha izakhi ze-purnent ze-sputum nezinye iziqu ze-mucus kanye nama-mucus freions kusuka ku-viscous to mncane. Ngaphezu kwalokho, inethuba eliqondile le-antioxidant eliqondile nge-Sulfhydryl Group yamahhala (Nucleophilic -SH) exhumana ngqo neqembu le-electrophile oxidation.

I-Bioreagent, i-API, i-SulfyHydryl Group (-SH) equkethwe ngaphakathi kwe-molecule yephula i-dispefide chain (-Ss) exhumanisa i-peptide chain ye-mucin e-mucus sputum. I-mucin iba ama-molekyuli amancane amaketanga we-peptide futhi anciphise ukunamathela kwe-sputum; Iphinde yephule imicu ye-DNA ngesipuni esihlanzayo, ngakho-ke ingancibilikisa hhayi kuphela i-sputum emhlophe kuphela kodwa futhi nesipuni esihlanzayo.

Ukwakheka kwamangqamuzana kwalo mkhiqizo kwenza kube lula ukudlula ngolwelwesi lwamaseli. Esitokisini, umkhiqizo we-duectytates ukuze wakhe i-l-cysteine, i-amino acid ebalulekile yokuhlanganiswa kwe-glutathione (GSH).

4. Isicelo:

Isetshenziswe ezifundweni ze-biochemical kanye nomuthi mucolytic. Isetshenziselwa ukuphefumula okubangelwa amanani amakhulu okuvinjezelwa kwe-mucous sputum. Ibuye isetshenziselwe ukufakwa kobuthi be-acetaminophen.
