L-cysteine, o se amino acid e masani ona maua i mea ola.O se tasi o sulfur-o loʻo i ai le α-amino acids.E liu lanu viole (lanu ona o le SH) i luma o le nitroprusside.E iai i le tele o polotini ma le glutathione.E mafai ona fausia ni mea e le mafai ona fa'afefeteina ma ion uamea e pei ole Ag+, Hg+, ma le Cu+.mercaptide.O lona uiga, RS-M', RSM"-SR (M', M" o metala monovalent ma divalent, faasologa).
Fua mole mole C3H7NO2S, mamafa mole 121.16.tioata lanu.Solu i le vai, acetic acid ma ammonia, e le mafai ona solu i le eter, acetone, ethyl acetate, benzene, carbon disulfide ma carbon tetrachloride.E mafai ona oxidized i cystine i le ea i vaifofo alkaline le faaituau ma vaivai.
Ole aoga ole L-Cysteine 99%:
1. Faʻaaogaina faʻapitoa i vailaʻau, mea teuteu, suʻesuʻega biochemical, ma isi.
2. E faʻaaogaina i le falaoa e faʻaleleia ai le faʻavaeina o le kulūlū, faʻaleleia le faʻafefeteina, faʻasaʻolotoina, ma puipuia le matua.
3. Fa'aaogaina i sua masani e puipuia ai le fa'ama'iina o le vaitamini C ma puipuia ai le sua mai le enaena.O lenei oloa o lo'o i ai aafiaga fa'amama ma e mafai ona fa'aoga mo le fa'a'ona o le acrylonitrile ma le fa'a'ona o mea manogi.
4. O lenei oloa e iai foʻi le aʻafiaga o le puipuia o le faʻaleagaina o le tino o le tagata, ma o se vailaʻau foi mo togafitiga o le bronchitis, aemaise lava o se vailaʻau faʻamaʻi faʻamaʻi (tele faʻaaogaina i le tulaga o le acetyl L-cysteine methyl ester. Cosmetics. e masani ona faʻaaogaina mo le matagofie Suavai, perm lotion, sunscreen cream, etc.
