Product Description
Tyrosinase muaj -daim ntawv ntawm ob nws N-terminus thiab C-terminus, thiab ob peb -helices ntawm N-terminus thiab C-terminus. Cov qauv no txhawb kev tsim ntawm qhov chaw nquag ntawm tyrosinase. Tyrosinase tau dav dav hauv cov kab mob, tsiaj txhu, nroj tsuag, thiab tib neeg. Hauv cov nroj tsuag, tyrosinase feem ntau hu ua polyphenol oxidase; Hauv kab, nws feem ntau hu ua phenol oxidase; thiab nyob rau hauv cov kab mob thiab tib neeg, nws yog hu ua tyrosinase. Tyrosinase yog ib qho tseem ceeb enzyme nyob rau hauv synthesis ntawm melanin nyob rau hauv cov kab mob thiab nyob rau hauv lub browning ntawm txiv hmab txiv ntoo thiab zaub. Nws ua lub luag haujlwm tseem ceeb hauv cov txheej txheem tanning thaum kab molting thiab kho qhov txhab. Cov kab mob melanin tuaj yeem tiv thaiv kab mob hlwb thiab spores los ntawm ultraviolet hluav taws xob puas. Tyrosinase muaj dual catalytic ua haujlwm li monophenolase thiab diphenolase. Raws li kev ua ntawm monophenolase, tyrosine yog hydroxylated rau L-DOPA. Raws li qhov kev txiav txim ntawm diphenolase, LDOPA yog oxidized rau dopaquinone, thiab dopaquinone tom qab ntawd dhau los ua cov tshuaj tiv thaiv melanin. Kev ua tyrosinase txawv txav tuaj yeem ua rau melanoma thiab ntxov- pib mob Alzheimer. Pigmentation tshwm sim los ntawm qhov txawv txav melanin ntau lawm yog ib qho tseem ceeb qhia txog kev laus ntawm cov tsiaj thiab browning nyob rau hauv txiv hmab txiv ntoo thiab zaub. Tyrosinase inhibitors muaj ntau yam kev siv, suav nrog kev zoo nkauj thiab kev saib xyuas kev noj qab haus huv, kev kho cov kab mob pigmentary, kev tswj kab mob thiab kab mob, thiab kev txuag zaub mov.
Cov txiaj ntsig yog dab tsi?
Tyrosinase yog ib qho tseem ceeb ntawm cov enzymes uas ua haujlwm ntau yam thiab ua haujlwm hauv tib neeg lub cev, feem ntau suav nrog cov hauv qab no:
1. Txhawb melanin synthesis
Tyrosinase yog ib qho tseem ceeb enzyme hauv melanin synthesis. Nws catalyzes hloov dua siab tshiab ntawm tyrosine rau dopa, uas yog ntxiv oxidized rau dopaquinone, thaum kawg tsim melanin. Cov txheej txheem no txiav txim siab pigmentation ntawm daim tawv nqaij, plaub hau, thiab ob lub qhov muag, cuam tshuam rau ib tus neeg cov tawv nqaij xim, plaub hau xim, thiab iris xim.
2. Tiv thaiv daim tawv nqaij los ntawm UV puas
Melanin muaj peev xwm nqus tau thiab tawg ntawm ultraviolet (UV) hluav taws xob. Tyrosinase txhawb kev tsim melanin, pab cov tawv nqaij tsim ib qho kev thaiv ntuj, txo UV kev puas tsuaj rau cov tawv nqaij, thiab txo qis kev pheej hmoo ntawm tshav ntuj, kev yees duab, thiab mob qog noj ntshav.
3. Kev koom tes hauv neurotransmitter synthesis
Nyob rau hauv lub paj hlwb, tyrosinase koom nyob rau hauv lub synthesis ntawm neurotransmitters xws li dopamine, muaj ib co kev cuam tshuam rau paj hlwb teeb liab, mus ob peb vas kev cai, thiab kev txawj ntse muaj nuj nqi, txawm hais tias lub luag hauj lwm no kuj yog me me.
4. Cov teebmeem Antioxidant
Qee qhov kev tshawb fawb qhia tias tyrosinase tuaj yeem muaj qee qhov muaj peev xwm antioxidant, pab txhawm rau tshem tawm cov dawb radicals thiab txo cov cellular oxidative puas tsuaj, tab sis qhov tseem ceeb ntawm cov nyhuv no hauv tib neeg lub cev xav tau kev tshawb fawb ntxiv.
Cov lus qhia siv
Tyrosinase, ib qho tseem ceeb oxidase, muaj kev siv dav hauv ntau qhov chaw. Cov hauv qab no yog nws cov chaw siv tseem ceeb:
1. Tshuaj pleev ib ce thiab tshuaj txhua hnub
- Kev Txhim Kho Cov Khoom Siv Dawb: Los ntawm inhibiting tyrosinase kev ua haujlwm, melanin ntau lawm yog txo, ua rau cov tshuaj pleev xim dawb, cov ntshav, thiab lwm yam khoom. Cov khoom xyaw xws li arbutin thiab kojic acid feem ntau yog siv los ua tyrosinase inhibitors.
- Bio-Dyeing plaub hau: Siv tyrosinase los ua kom muaj kev hloov pauv ntawm tyrosine mus rau hauv melanin, ua tiav cov txheej txheem ntawm cov plaub hau dyeing thiab ib puag ncig zoo. Piv txwv li, tyrosinase-raws li bio-cov plaub hau dyeing tshuab tuaj yeem npaj ib nrab- cov plaub hau dyes mus tas li.
2. Pharmaceuticals thiab Biomedicine
- Kev Kho Mob Dermatology: Hauv kev kho cov kab mob xws li vitiligo thiab hyperpigmentation, cov tswv yim kho mob yog tsim los ntawm kev tswj hwm kev ua tyrosinase lossis siv nws cov khoom catalytic. Piv txwv li, tyrosinase tuaj yeem siv los ua kom muaj zog hauv -situ tiam ntawm cov tshuaj kho.
- Tshuaj Synthesis: Siv los tsim cov tshuaj xws li levodopa (L-DOPA) thiab tsim cov tshuaj tiv thaiv kab mob los ntawm cov tshuaj tiv thaiv bioorthogonal, kov yeej cov teeb meem tshuaj tiv thaiv.
3. Kev lag luam zaub mov
- Txhim kho xim xim: koom nrog oxidation ntawm phenolic tshuaj thaum lub sij hawm ua zaub mov, txhim kho xim thiab tsw ntawm cov khoom xws li tshuaj yej, kas fes, thiab chocolate.
- Khoom noj khoom haus Additives: Siv nws cov ntoo khaub lig- txuas cov khoom raws li cov khoom noj ntxiv los txhim kho cov zaub mov zoo nkauj thiab ruaj khov.
