Iyo yekuchena nzira ye arbutin
Zviri mukati uye kugovera kwemelanin ndizvo zvinhu zvikuru zvinotarisa kudzika kwemavara eganda. Melanin inogadzirwa muma melanocytes mu basal layer yeganda epidermis. Iyo inozopedzisira yaumbwa kubva ku tyrosine pasi pechiito che tyrosinase kuburikidza nekutevedzana kwakaoma biochemical reaction. Iyo inotamiswa kubva ku basal layer kuenda kune yekunze layer ye epidermis kubva mukati nekunze kuburikidza ne synapses. Pera ganda.
Tyrosinase ine tyrosine hydroxylase chiitiko (inokonzera tyrosine kugadzira dopa) uye dopa oxidase chiitiko (catalyzing dopa kugadzira dopaquinone). Mukuita kwekuumbwa kwe melanin, inoshanda seyakanyanya chiyero-inomisa enzyme. Basa rayo rinotarisa huwandu hwe melanin yakaumbwa.
Arbutin inonzi tyrosinase inhibitor inogona kunyatso kuvharidzira basa re tyrosinase pasina kukanganisa kuwedzera kwesero. Inokwikwidza kusungwa kwedopa kuburikidza nekusunga kwayo kwakananga kune tyrosinase. saiti, inovhara synthesis yedopa uye dopaquinone, nekudaro ichikanganisa melanocytes uye ichitadzisa kugadzirwa kwe melanin. Panguva imwecheteyo, inewo basa rekuita diluting yakaumbwa melanin, kukurumidza kuora uye kubuda kwe melanin, kuderedza ganda reganda, uye kubvisa mavara uye freckles.
