L-cysteine Base | 52-90-4
Fa'amatalaga o oloa:
Cysteine o le tioata paʻepaʻe poʻo le paʻu tioata, solu i le vai, sina manogi, e le mafai ona faʻaaogaina i le ethanol, e le mafai ona faʻaogaina i soʻo faʻaola pei ole eter. Liu liusuavai 240 ℃, monoclinic system. O le Cysteine o se tasi o vailaʻau amino o loʻo i ai le sulfur, o se amino acid e le taua.
I totonu o le tino, o le sulfur atom o le methionine ua suia i le hydroxyl oxygen atom o serine, ma faʻapipiʻiina e ala i le cystathionine.
Mai le cysteine, e mafai ona gaosia le glutathione. glycerol. Cysteine e fa'amautu fa'ama'i, ae faigofie ona fa'ama'iina i le cystine i vaifofo fa'aitutū ma alkaline.
Le aoga ole L-cysteine Base:
E iai le felagolagomai i le tino, ma isi.
Fa'atino lelei le puipuia ma le togafitia o manu'a fa'avevela.
E fa'atumauina le gaioiga o le sulfhydrylase taua i le gaosiga o le keratin o polotini o le pa'u, ma fa'aopoopo vaega o le sulfur e fa'amautu ai le metabolism masani o le pa'u ma fa'atonutonu le melanin o lo'o i lalo e gaosia e le pigmenti i le pito i lalo o le epidermis. O se mea e sili ona lelei fa'alenatura pa'epa'e teuteu.
Soo se taimi lava e tupu ai le mumū poʻo le allergy, o le sulfydrylase e pei o le cholphosphatase e faʻaitiitia, ma le L-cysteine faʻaopoopo e mafai ona faʻatumauina le gaioiga o le sulfydrylase ma faʻaleleia aʻafiaga o le paʻu o le mumū ma le allergy.
E i ai le aʻafiaga o le faʻamavaeina o le keratin, o lea e aoga foi mo faʻamaʻi paʻu ma le keratin hypertrophy.
E iai le galuega e puipuia ai le soifua matua.
