L-Cysteine 99% | 52-90-4
Ingcaciso yeMveliso:
L-cysteine, i-amino acid edla ngokufumaneka kwizinto eziphilayo. Ngomnye wesulfure-equlethe i-α-amino acids. Ijika ibemfusa (umbala ngenxa ye-SH) kubukho be nitroprusside. Ikhona kwiiprotheni ezininzi kunye ne-glutathione. Inokwenza iikhompawundi ezinganyibilikiyo kunye neeyoni zetsimbi ezifana ne-Ag +, Hg +, kunye neCu +. imercaptide. Oko kukuthi, i-RS-M', i-RSM"-SR (M', M" yintsimbi enye kunye ne-divalent, ngokulandelanayo).
I-molecular formula C3H7NO2S, ubunzima bemolekyuli 121.16. Iikristale ezingenambala. Inyibilika emanzini, i-acetic acid kunye ne-ammonia, ayinyibiliki kwi-ether, i-acetone, i-ethyl acetate, i-benzene, i-carbon disulfide kunye ne-carbon tetrachloride. Inokuthi i-oxidized kwi-cystine ngomoya kwizisombululo ze-alkaline ezingathathi hlangothi kunye nezibuthathaka.
Ukusebenza kwe-L-Cysteine 99%:
1. Isetyenziswa kakhulu kwiyeza, izimonyo, uphando lwe-biochemical, njl.
2. Isetyenziselwa kwisonka ukukhuthaza ukubunjwa kwe-gluten, ukukhuthaza ukuvutshelwa, ukukhululwa kwesikhunta, kunye nokukhusela ukuguga.
3. Isetyenziswe kwiijusi zendalo ukukhusela i-oxidation ye-vitamin C kunye nokukhusela ijusi ekukhanyeni. Le mveliso ineempembelelo ze-detoxification kwaye ingasetyenziselwa ubuthi be-acrylonitrile kunye netyhefu ye-asidi enevumba elimnandi.
4. Le mveliso nayo inefuthe lokuthintela umonakalo wemitha emzimbeni womntu, kwaye ikwalichiza lokunyanga i-bronchitis, ngakumbi njengechiza lokukhulula i-phlegm (isetyenziswa kakhulu ngendlela ye-acetyl L-cysteine methyl ester. Izithambiso zisetyenziselwa ubuhle Amanzi, i-perm lotion, i-sunscreen cream, njl.
