L-Cysteine 99% | 52-90-4
Whakaahuatanga Hua:
L-cysteine, he waikawa amino e kitea ana i roto i nga rauropi ora. Koia tetahi o nga waikawa α-amino kei roto he whanariki. Ka huri te papura (he tae na te SH) i te aroaro o te nitroprusside. Kei roto i te maha o nga pūmua me te glutathione. Ka taea te hanga i nga pūhui korekore me nga katote whakarewa penei i te Ag+, Hg+, me te Cu+. hokohoko. Arā, RS-M', RSM"-SR (M', M" he monovalent me te divalent konganuku, ia).
tātai rāpoi C3H7NO2S, taumaha rāpoi 121.16. Kiriata kore tae. Ka whakarewahia ki te wai, te waikawa ahetiki me te haukini, kare e rewa i te etera, te acetone, te ethyl acetate, te benzene, te waro disulfide me te waro tetrachloride. Ka taea te waikura ki te cystine ma te hau i roto i nga otinga kawakore me te ngoikore.
Ko te kaha o te L-Cysteine 99%:
1. Te nuinga whakamahia i roto i te rongoa, poke, rangahau biochemical, etc.
2. Ka whakamahia i roto i te taro hei whakatairanga i te hanganga o te gluten, te whakatairanga i te fermentation, te tuku i te pokepokea ai, me te aukati i te koroheketanga.
3. Ka whakamahia i roto i nga wai maori hei aukati i te waiora o te huaora C me te aukati i te wai kia parauri. Ko tenei hua he awenga whakaheke ka taea te whakamahi mo te paihana acrylonitrile me te paihana waikawa kakara.
4. Ka whai hua ano tenei hua ki te aukati i te kino o te rauropi ki te tinana o te tangata, he rongoa ano hoki mo te maimoatanga o te bronchitis, ina koa he rongoa whakaheke i te phlegm (te nuinga ka whakamahia i te ahua o te acetyl L-cysteine methyl ester. Cosmetics Ka whakamahia te nuinga mo te wai ataahua, te hinu perm, te kirīmi parepare, etc.
