Isisekelo se-L-cysteine | 52-90-4
Incazelo Yomkhiqizo:
I-Cysteine i-crystal emhlophe noma i-crystalline powder, inyibilika emanzini, inephunga kancane, ayincibiliki ku-ethanol, ayincibiliki kuzinyibilikisi zemvelo njenge-ether. Iphoyinti lokuncibilika 240 ℃, uhlelo lwe-monoclinic. I-Cysteine ingenye yama-amino acid anesulfure, okuyi-amino acid engabalulekile.
Emzimbeni, i-athomu yesibabule ye-methionine ithathelwa indawo i-athomu ye-hydroxyl oxygen ye-serine, futhi ihlanganiswa nge-cystathionine.
Kusuka ku-cysteine, i-glutathione ingakhiqizwa. i-glycerol. I-cysteine i-asidi ezinzile, kodwa i-oxidized kalula ku-cystine kuzixazululo ezingathathi hlangothi ne-alkaline.
Ukusebenza kwe-L-cysteine Base:
Inobumbano emzimbeni, njll.
Vimbela futhi welaphe ngempumelelo ukulimala kwemisebe.
Igcina umsebenzi we-sulfhydrylase ebalulekile ekukhiqizweni kwe-keratin yamaprotheni esikhumba, futhi yengeza amaqembu esibabule ukuze kugcinwe umzimba ojwayelekile wesikhumba futhi ilawule i-melanin engaphansi ekhiqizwa amangqamuzana e-pigment ongqimbeni oluphansi kakhulu lwe-epidermis. Kuyizimonyo zemvelo ezimhlophe ezimhlophe.
Noma nini lapho ukuvuvukala noma ukungezwani komzimba kwenzeka, i-sulfidrylase efana ne-cholphosphatase iyancipha, futhi i-L-cysteine supplementation ingagcina umsebenzi we-sulfidrylase futhi ithuthukise izimpawu zesikhumba zokuvuvukala nokungezwani komzimba.
Inomphumela wokuqedwa kwe-keratin, ngakho-ke iyasebenza nasezifweni zesikhumba nge-keratin hypertrophy.
Inomsebenzi wokuvimbela ukuguga kwezinto eziphilayo.
