Isiseko se-L-cysteine | 52-90-4
Ingcaciso yeMveliso:
I-Cysteine yikristale emhlophe okanye i-crystalline powder, inyibilika emanzini, inevumba elincinane, ayinyibiliki kwi-ethanol, enganyibilikiyo kwizinyibilikisi ze-organic ezifana ne-ether. Indawo yokunyibilika 240 ℃, inkqubo ye-monoclinic. I-Cysteine yenye yee-amino acids ezinesulfure, engabalulekanga njenge-amino acid.
Kwi-organism, i-athomu yesulfure ye-methionine ithathelwa indawo ye-athomu ye-oksijini ye-hydroxyl ye-serine, kwaye ihlanganiswe nge-cystathionine.
Ukusuka kwi-cysteine, i-glutathione inokuveliswa. iglycerol. I-cysteine i-asidi ezinzileyo, kodwa i-oxidized ngokulula kwi-cystine kwizisombululo ezingathathi hlangothi kunye ne-alkaline.
Ukusebenza kwe-L-cysteine Base:
Inobumbano emzimbeni, njl.
Ukuthintela ngokufanelekileyo kwaye unyange ukwenzakala ngemitha.
Igcina umsebenzi we-sulfhydrylase ebalulekileyo kwimveliso ye-keratin yeeprotheni zesikhumba, kwaye yongeza amaqela e-sulfure ukugcina i-metabolism eqhelekileyo yolusu kunye nokulawula i-melanin ephantsi eveliswa ziiseli ze-pigment kweyona ndawo iphantsi ye-epidermis. Yeyona nto ifanelekileyo yokwenza mhlophe ngokwendalo.
Nanini na xa ukuvuvukala okanye i-allergies kwenzeka, i-sulfidrylase efana ne-cholphosphatase iyancitshiswa, kwaye i-L-cysteine supplementation inokugcina umsebenzi we-sulfidrylase kunye nokuphucula iimpawu zesikhumba zokuvuvukala kunye nokwaliwa.
Inomphumela wokuchithwa kwekeratin, ngoko ke iyasebenza nakwizifo zesikhumba kunye ne-keratin hypertrophy.
Inomsebenzi wokuthintela ukuguga kwezinto eziphilayo.
