L-cysteine Base | 52-90-4
Mafotokozedwe Akatundu:
Cysteine ndi kristalo woyera kapena ufa wonyezimira, wosungunuka m'madzi, wonunkhira pang'ono, wosasungunuka mu ethanol, wosasungunuka mu zosungunulira za organic monga ether. Malo osungunuka 240 ℃, monoclinic system. Cysteine ndi imodzi mwa ma amino acid omwe ali ndi sulfure, omwe ndi amino acid osafunikira.
Mu chamoyo, atomu sulfure wa methionine m'malo ndi hydroxyl mpweya atomu ya serine, ndipo apanga kudzera cystathionine.
Kuchokera ku cysteine, glutathione imatha kupangidwa. glycerol. Cysteine ndi yokhazikika ya asidi, koma imasungunuka mosavuta ku cystine mu njira zopanda ndale komanso zamchere.
Mphamvu ya L-cysteine Base:
Lili ndi mgwirizano mu thupi, etc.
Kuteteza ndi kuchiza kuvulala kwa radiation.
Imasunga ntchito ya sulfhydrylase yofunika kwambiri pakupanga mapuloteni a khungu la keratin, ndikuwonjezera magulu a sulfure kuti khungu likhalebe ndi kagayidwe kachakudya komanso kuwongolera melanin yomwe imapangidwa ndi ma cell a pigment omwe ali m'munsi kwambiri wa epidermis. Ndi bwino kwambiri zachilengedwe whitening zodzikongoletsera.
Nthawi zonse kutupa kapena ziwengo zikachitika, sulfydrylase monga cholphosphatase imachepetsedwa, ndipo L-cysteine supplementation imatha kupitiriza ntchito ya sulfydrylase ndikuwongolera zizindikiro za khungu za kutupa ndi ziwengo.
Zili ndi zotsatira za kusungunuka kwa keratin, kotero ndizothandizanso pa matenda a khungu ndi keratin hypertrophy.
Lili ndi ntchito yoletsa kukalamba kwachilengedwe.
