Arbutinchinhu chinowanikwa mumiti yakasiyana-siyana yakadai se bearberry, cranberries, uye blueberries. Yakawana kutariswa kukuru muindasitiri yekuchengetedza ganda uye cosmetic nekuda kwesimba rayo rekuchenesesa ganda uye kupenya. Maitiro ari shure kwemhedzisiro yekuchena kwearbutin anoenderana nekukwanisa kwayo kudzivirira kushanda kwe enzyme inonzi tyrosinase, iyo inoita basa rakakosha mukugadzirwa kwe melanin - pigment inokonzera ganda, bvudzi, uye ruvara rwemaziso.
Ruvara rweganda runobva pahuwandu uye kupararira kwemelanin inogadzirwa nemelanocytes, masero akasarudzika ari muchikamu che epidermal layer. Tyrosinase ienzyme inokosha munzira yekugadzira melanin, ichikurudzira kushandurwa kweamino acid tyrosine kuita melanin precursors, izvo zvinozopedzisira zvaita kuti pave ne melanin pigments. Arbutin inoita kuti tyrosinase ichene zvakanyanya kuburikidza nekudzivirira tyrosinase activity nemakwikwi.
Arbutin ine chisungo cheglycoside, chinova chisungo chemakemikari pakati pemorekuru yeglucose nemorekuru yehydroquinone. Hydroquinone chinhu chinozivikanwa chine hunhu hwekujekesa ganda, asi chinogona kuva chakaoma paganda uye chine chekuita nemigumisiro inogona kuitika. Arbutin, kune rumwe rutivi, inoshanda senzira iri nani pane hydroquinone uku ichiri kupa kudzivirira kugadzirwa kwemelanin.
Kana arbutin ikashandiswa paganda, inonyudzwa uye inogadziriswa kuita hydroquinone kuburikidza nemaitiro enzymatic. Iyi hydroquinone inozodzivisa kushanda kwetyrosinase nekukwikwidzana nekugara panzvimbo yayo inoshanda. Nekuda kweizvozvo, mamorekuru etyrosine haagone kushandurwa zvinobudirira kuita melanin precursors, zvichikonzera kudzikira kwekugadzirwa kwemelanin. Izvi zvinoguma nekuderera zvishoma nezvishoma kweruvara rweganda, zvichikonzera kuti ganda rive rakajeka uye rakafanana.
Zvakakosha kuziva kutikuchena kwearbutinMhedzisiro yacho haikurumidzi kuitika. Kuchinja kweganda kunotora mwedzi, saka kushandisa nguva dzose uye kwenguva refu zvigadzirwa zvine arbutin kwakakosha kuti uone shanduko dzinoonekwa mukuchinja kweruvara rweganda. Pamusoro pezvo, mashandiro earbutin anoshanda zvakanyanya pakugadzirisa matambudziko ane chekuita nekuwedzera kweruvara rweganda, akadai semavanga ezera, mavanga ezuva, uye melasma, pane kuchinja ruvara rweganda rwekare.
Kuchengetedzwa kweArbutin kunowanzo bvumidzwa zviri nani pane zvimwe zvinogadzirisa ganda, zvichiita kuti ive sarudzo yakakurumbira kune vanhu vanoda kugadzirisa ganda risina kuenzana. Zvisinei, maitiro emunhu mumwe nemumwe anogona kusiyana, uye zvinokurudzirwa kuti uedze bvunzo yeganda usati waisa zvigadzirwa zvitsva zvekuchengetedza ganda muchirongwa chako.
Mukupedzisa, nzira yekuchenesesa ganda yearbutin inoenderana nekukwanisa kwayo kudzivirira kushanda kwetyrosinase, zvichikonzera kudzikira kwekugadzirwa kwemelanin. Kudzikiswa kwayo kwetyrosinase nemakwikwi, zvichikonzera kudzikira kwekugadzirwa kwemelanin, kunoita kuti ive chinhu chinokwezva muzvigadzirwa zvekuchengetedza ganda zvakanangana nekuwedzera kwepigmentation uye ganda risina kuenzana. Sezvineiwo nechero chinhu chekuchengetedza ganda, zvinokurudzirwa kubvunza chiremba weganda usati watanga zvigadzirwa zvitsva mumaitiro ako, kunyanya kana uine matambudziko eganda kana mamiriro ezvinhu.
