L-cysteine Base | 52-90-4
Product Description:
Cysteine i crystal chena kana crystalline poda, inonyungudika mumvura, inonhuwa zvishoma, isinganyunguriki mu ethanol, isinganyunguriki muorganic solvents senge ether. Melting point 240 ℃, monoclinic system. Cysteine ndechimwe chesarufa-ine amino acids, iyo isiri yakakosha amino acid.
Muchipenyu, atomu yesarufa yemethionine inotsiviwa nehydroxyl okisijeni atomu ye serine, uye inogadzirwa kuburikidza necystathionine.
Kubva kucysteine, glutathione inogona kugadzirwa. glycerol. Cysteine yakagadzikana asidhi, asi inogadziriswa nyore nyore kune cystine mune zvakarerekera uye alkaline mhinduro.
Kubudirira kweL-cysteine Base:
Iine kubatana mumuviri, nezvimwe.
Kudzivirira uye kurapa kukuvara kwemwaranzi.
Inochengetedza basa reyakakosha sulfhydrylase mukugadzirwa kwekeratin yemapuroteni eganda, uye inowedzera sulfuri mapoka kuchengetedza yakajairika metabolism yeganda uye kudzora iri pasi pe melanin inogadzirwa nepigment masero ari pasi peiyo epidermis. Iyo yakanaka chaizvo yakasikwa yekuchena cosmetic.
Pese panoitika kuzvimba kana allergy, iyo sulfydrylase senge cholphosphatase inoderedzwa, uye L-cysteine yekuwedzera inogona kuchengetedza basa re sulfydrylase uye inovandudza zviratidzo zveganda zvekuzvimba uye allergies.
Iyo ine mhedzisiro yekunyungudutsa keratin, saka inoshandawo kune zvirwere zveganda ne keratin hypertrophy.
Iine basa rekudzivirira kukwegura kwehupenyu.
