L-cysteine Base | 52-90-4
Ibisobanuro ku bicuruzwa:
Cysteine ni ifu ya kirisiti yera cyangwa ifu ya kristaline, ikabura mumazi, impumuro nkeya, idashobora gushonga muri Ethanol, idashonga mumashanyarazi nka ether. Gushonga ingingo 240 ℃, sisitemu ya monoclinic. Cysteine ni imwe muri sulfure irimo aside amine, ni aside amine idakenewe.
Mu binyabuzima, atome ya sulfure ya methionine isimburwa na hydroxyl ogisijeni atom ya serine, kandi igahuzwa binyuze muri cystathionine.
Kuva kuri sisitemu, glutathione irashobora kubyara. glycerol. Cysteine ihagaze neza, ariko irashobora guhumeka byoroshye kuri cystine mubisubizo bidafite aho bibogamiye na alkaline.
Ingaruka za Base ya L-cysteine:
Ifite ubumwe mu mubiri, nibindi.
Kurinda neza no kuvura ibikomere byimirasire.
Ikomeza ibikorwa bya sulfhydrylase yingenzi muri keratine ikora proteine zuruhu, ikanongerera amatsinda ya sulfure kugirango igumane metabolisme isanzwe yuruhu kandi igenzure melanine yimbere ikorwa ningirabuzimafatizo yibice byo hasi ya epidermis. Nibintu byiza cyane byo kwisiga byera.
Igihe cyose habaye umuriro cyangwa allergie, sulfydrylase nka cholphosphatase iragabanuka, kandi inyongera ya L-cysteine irashobora gukomeza ibikorwa bya sulfydrylase no kunoza ibimenyetso byuruhu rwumuriro na allergie.
Ifite ingaruka zo gushonga keratine, bityo ikagira akamaro no kurwara uruhu hamwe na keratin hypertrophy.
Ifite umurimo wo gukumira gusaza kw'ibinyabuzima.
