●N'chifukwa Chiyani Thupi la Munthu Limatulutsa Melanin?
Dzuwa ndilomwe limayambitsa kupanga melanin. Kuwala kwa dzuwa kumawononga deoxyribonucleic acid, kapena DNA, m'maselo. Kuwonongeka kwa DNA kungayambitse kuwonongeka ndi kutayika kwa chidziwitso cha majini, komanso kuchititsa kusintha koopsa kwa majini, kapena kutayika kwa majini opondereza chotupa, zomwe zimapangitsa kuti pakhale zotupa.
Komabe, kuwala kwa dzuwa sikuli "koopsa", ndipo zonsezi ndi "ngongole" ya melanin. Ndipotu, panthawi yovuta kwambiri, melanin idzatulutsidwa, ikugwira bwino mphamvu ya kuwala kwa ultraviolet, kuteteza DNA kuti isawonongeke, motero kuchepetsa kuwonongeka kwa kuwala kwa ultraviolet ku thupi la munthu. Ngakhale melanin imateteza thupi la munthu kuti isawonongeke ndi ultraviolet, imathanso kupangitsa khungu lathu kukhala lakuda ndikukulitsa mawanga. Chifukwa chake, kutsekereza kupanga melanin ndi njira yofunika kwambiri yoyeretsera khungu m'makampani okongola.
●KodiArbutin?
Arbutin, yemwenso amadziwika kuti arbutin, ali ndi mankhwala a C12H16O7. Ndi chinthu chochokera ku masamba a Ericaceae chomera bearberry. Ikhoza kulepheretsa ntchito ya tyrosinase m'thupi ndikuletsa kupanga melanin, potero kuchepetsa khungu la pigmentation, kuchotsa mawanga ndi mawanga. Imakhalanso ndi bactericidal ndi anti-inflammatory effect ndipo imagwiritsidwa ntchito makamaka mu zodzoladzola.
Arbutinakhoza kugawidwa mu α-mtundu ndi β-mtundu malinga ndi mapangidwe osiyanasiyana. Kusiyana kwakukulu pakati pa ziwirizo muzinthu zakuthupi ndi kuzungulira kwa kuwala: α-arbutin ndi pafupifupi madigiri 180, pamene β-arbutin ndi pafupifupi -60. Onsewa amakhala ndi zotsatira zoletsa tyrosinase kuti akwaniritse kuyera. Chogwiritsidwa ntchito kwambiri ndi mtundu wa β, womwe ndi wotsika mtengo. Komabe, malinga ndi kafukufuku, kuwonjezera α-mtundu wofanana ndi 1/9 wa ndende ya β-mtundu kumatha kulepheretsa kupanga tyrosinase ndikukwaniritsa kuyera. Zinthu zambiri zosamalira khungu zokhala ndi α-arbutin zowonjezeredwa zimakhala ndi zoyera kwambiri kuposa arbutin wamba.
● Ubwino Wake Ndi ChiyaniArbutin?
Arbutin makamaka yotengedwa masamba a bearberry. Zimapezekanso mu zipatso ndi zomera zina. Zimakhala ndi zotsatira zowunikira khungu. Imatha kulowa mwachangu pakhungu popanda kukhudza maselo akhungu. Zimaphatikizana ndi tyrosine, zomwe zimayambitsa kupanga melanin, ndipo zimatha kuletsa ntchito ya tyrosinase ndi kupanga melanin, kufulumizitsa kuwonongeka ndi kuchotsedwa kwa melanin. Kuphatikiza apo, arbutin imatha kuteteza khungu ku ma free radicals ndipo imakhala ndi hydrophilicity yabwino. Chifukwa chake, nthawi zambiri amawonjezeredwa kuzinthu zoyera pamsika, makamaka m'maiko aku Asia.
Arbutinndi chilengedwe chogwira ntchito chochokera ku zomera zobiriwira. Ndi gawo lachikopa la decolorizing lomwe limaphatikiza "zomera zobiriwira, zotetezeka komanso zodalirika" ndi "decolorization yabwino". Imatha kulowa mwachangu pakhungu. Popanda kukhudza kuchuluka kwa maselo, imatha kuletsa ntchito ya tyrosinase pakhungu ndikuletsa mapangidwe a melanin. Pophatikizana mwachindunji ndi tyrosinase, imathandizira kuwonongeka ndi kutuluka kwa melanin, potero kuchepetsa khungu la pigmentation, kuchotsa mawanga ndi madontho, ndipo alibe poizoni, zokwiyitsa, zolimbikitsa komanso zotsatira zina pa melanocytes. Ilinso ndi bactericidal ndi anti-inflammatory effect. Ndiwotetezeka kwambiri komanso wothandiza kwambiri pakuyeretsa zopangira zotchuka masiku ano, komanso ndi njira yabwino yoyeretsera khungu komanso mawanga azaka zam'ma 21.
●Kodi Kugwiritsa Ntchito Kwambiri Ndi Chiyani?Arbutin?
Zitha kugwiritsidwa ntchito muzodzoladzola zapamwamba ndipo zimatha kupangidwa kukhala zonona zosamalira khungu, zonona zonona, zonona za ngale, ndi zina zotero.
Zida zopangira mankhwala oyaka ndi scald: Arbutin ndiye chinthu chofunikira kwambiri pakuwotcha kwatsopano ndi mankhwala a scald, omwe amadziwika ndi kupumula kwachangu, mphamvu yolimbana ndi kutupa, kuchotsa mwachangu zofiira ndi kutupa, kuchiritsa mwachangu, komanso popanda zipsera.
Fomu ya mlingo: kupoperani kapena kupaka.
Zopangira mankhwala a m'mimba odana ndi kutupa: zabwino bactericidal ndi odana ndi kutupa zotsatira, palibe poizoni mavuto.
