Khukusi lathu limayendetsedwa ndi mapuloteni ofiira m'madzi athu owoneka bwino, ndi utoto wowala wa melanin. Melanocytes amatha kupanga melanin. Mtundu wa khungu umakhudzidwa kwambiri ndi zomwe zili ndi kufalitsa kwa utoto. The Epirmal wosanjikiza khungu amatha kugawidwa m'magawo asanu, ndipo melanocytes ali mu basembala wosanjikiza. Khungu limalimbikitsidwa (makamaka pamphepete mwa ulfiokiolet
Mukupanga melanin melation, trissinase imakonda gawo lofunikira kwambiri. Ntchito ya tyssinase ikachuluka, melanin ambiri adzapangidwa. Ngati ntchito ya ma tressinase imayang'aniridwa, zotsatira za Melanocytes kupanga melanin imachepetsedwa. Palibe kukayikira kuti Terrossinase ndichizindikiro cha kuwongolera melanin, motero titha kuyamba mwa kuchepetsa mapangidwe a Tyrossinase ndi kupondereza ntchito ya Tyrossinase.
Peptide-Oligoptetdide-68 yomwe ingalepheretse mapangidwe a Melanin
Ndi mtundu wa zinthu zoyera zoyera. Ndi olemera olemera mu 12 amino acid. Nthawi zambiri imagwiritsidwa ntchito yoyera komanso yowala pakhungu, kuthetsa mawanga ndi ziphuphu. Amachepetsa kupanga ma tenin ndipo imalepheretsa kwambiri melalanin pomupatsa ma melaninotropic mahomoni. Mfundo yake yapadera ndiyakuti oligoptetide-68 imagwirizana ndi ma tgf-β kwa ma cell a mitf intramolecular njira yopanda tanthauzo komanso yowala. Zimachepetsa kuchuluka kwa mamolekyulu omwe akukhudzidwa ndi melalanin kupanga ndikugwiritsa ntchito tyrosinase ntchito ndi ma melanir.
