L-cysteine Base |52-90-4
Whakaahuatanga Hua:
Ko te Cysteine he karaihe ma, he paura tioata ranei, he wairewa ki te wai, he paku kakara, he kore e rewa i roto i te waihano, he koretake i roto i nga whakarewa pararopi penei i te etera.Ira whakarewa 240 ℃, pūnaha monoclinic.Ko te Cysteine tetahi o nga waikawa amino whanariki kei roto, he waikawa amino-kore.
I roto i te rauropi, ka whakakapihia te ngota whanariki o te methionine ki te ngota hāora hydroxyl o serine, ka whakahiatotia ma te cystathionine.
Mai i te cysteine, ka taea te hanga glutathione.glycerol.He waikawa pūmau te Cysteine, engari he ngawari te waikura ki te cystine i roto i nga otinga koretake me te kawakore.
Te kaha o te L-cysteine Base:
He hononga kei roto i te tinana, aha atu.
He pai te aukati me te rongoa i te whara iraruke.
Ka mau tonu te mahi o te sulfhydrylase nui i roto i te hanga keratin o nga pūmua kiri, me te taapiri i nga roopu whanariki ki te pupuri i te kawa noa o te kiri me te whakahaere i te melanin o raro i hangaia e nga pūtau poaka i te paparanga o raro o te epidermis.Ko te tino pai te Paku māori māori.
I nga wa katoa ka puta te mumura me te mate mate, ka whakahekehia te sulfydrylase penei i te cholphosphatase, ka taea e te taapiri L-cysteine te pupuri i te mahi o te sulfydrylase me te whakapai ake i nga tohu kiri o te mumura me te mate mate.
He painga o te whakakore i te keratin, no reira he pai mo nga mate kiri me te hypertrophy keratin.
He mahi hei aukati i te koroheketanga koiora.
