L-Cysteine 99% | 52-90-4
Ibisobanuro ku bicuruzwa:
L-cysteine, aside amine ikunze kuboneka mubinyabuzima. Nimwe muri sulfure irimo α-amino acide. Ihinduka ibara ry'umuyugubwe (ibara bitewe na SH) imbere ya nitroprusside. Iraboneka muri poroteyine nyinshi na glutathione. Irashobora gukora ibice bidashobora gushonga hamwe nicyuma nka Ag +, Hg +, na Cu +. mercaptide. Ni ukuvuga, RS-M ', RSM "-SR (M', M" ni ibyuma byikurikiranya kandi bihwanye).
Inzira ya molekuline C3H7NO2S, uburemere bwa molekile 121.16. Kirisiti itagira ibara. Gushonga mumazi, acide acike na ammonia, kudashonga muri ether, acetone, Ethyl acetate, benzene, carbone disulfide na tetrachloride. Irashobora kuba okiside kuri cystine n'umwuka mubisubizo bitagira aho bibogamiye.
Ingaruka za L-Cysteine 99%:
1. Ahanini ikoreshwa mubuvuzi, kwisiga, ubushakashatsi bwibinyabuzima, nibindi.
2. Ikoreshwa mumigati kugirango iteze imbere gluten, itume fermentation, irekurwa, kandi irinde gusaza.
3. Ikoreshwa mumitobe karemano kugirango wirinde okiside ya vitamine C no kwirinda umutobe wijimye. Iki gicuruzwa gifite ingaruka zo kwangiza kandi kirashobora gukoreshwa muburozi bwa acrylonitrile hamwe nuburozi bwa acide aromatic.
4. Iki gicuruzwa kandi gifite ingaruka zo gukumira imirasire yangiza umubiri wumuntu, kandi ni n'umuti wo kuvura bronhite, cyane cyane nk'umuti worohereza flegm (ahanini ukoreshwa muburyo bwa acetyl L-cysteine methyl ester. Cosmetics zikoreshwa cyane mubwiza Amazi, amavuta yo kwisiga, amavuta yizuba, nibindi.
