Kusiyana pakati pa α-arbutin ndi β-arbutin

α-arbutinndi β-arbutin ndi mankhwala awiri ogwirizana kwambiri omwe amagwiritsidwa ntchito nthawi zambiri muzinthu zosamalira khungu kuti aziwunikira komanso kuwunikira.Ngakhale kuti amagawana dongosolo lofanana ndi momwe amagwirira ntchito, pali kusiyana kwakukulu pakati pa ziwirizi zomwe zingakhudze mphamvu zawo komanso zotsatira zake.

Mwamadongosolo, onse α-arbutin ndi β-arbutin ndi ma glycosides a hydroquinone, zomwe zikutanthauza kuti ali ndi molekyulu ya shuga yolumikizidwa ku molekyulu ya hydroquinone.Kufanana kwapangidwe kumeneku kumapangitsa kuti zinthu zonse ziwirizi ziletse enzyme tyrosinase, yomwe imakhudzidwa ndi kupanga melanin.Poletsa tyrosinase, mankhwalawa amatha kuthandizira kuchepetsa kupanga melanin, zomwe zimapangitsa kuti khungu likhale lowala komanso ngakhale khungu.

Kusiyana kwakukulu pakati pa α-arbutin ndi β-arbutin kuli m'malo a mgwirizano wa glycosidic pakati pa magulu a glucose ndi hydroquinone:

α-arbutin: Mu α-arbutin, chomangira cha glycosidic chimalumikizidwa pamalo a alpha a mphete ya hydroquinone.Kuyika uku kumakhulupirira kuti kumapangitsa kukhazikika komanso kusungunuka kwa α-arbutin, ndikupangitsa kuti ikhale yogwira ntchito kwambiri pakhungu.Mgwirizano wa glycosidic umachepetsanso kuthekera kwa okosijeni wa hydroquinone, zomwe zingayambitse kupanga zinthu zakuda zomwe zimatsutsana ndi zomwe zimafunidwa zowunikira khungu.

β-arbutin: Mu β-arbutin, chomangira cha glycosidic chimalumikizidwa pamalo a beta a mphete ya hydroquinone.Ngakhale β-arbutin imagwiranso ntchito poletsa tyrosinase, ikhoza kukhala yosakhazikika kuposa α-arbutin komanso sachedwa kutulutsa okosijeni.Oxidation iyi imatha kupangitsa kuti pakhale zopangira zofiirira zomwe sizifunikanso kuwunikira khungu.

Chifukwa cha kukhazikika kwake komanso kusungunuka kwake, α-arbutin nthawi zambiri imawonedwa ngati yothandiza kwambiri komanso yokondedwa pakugwiritsa ntchito skincare.Amakhulupirira kuti amapereka zotsatira zabwino zowunikira khungu ndipo sangayambitse kusinthika kapena zotsatira zosafunika.

Poganizira zinthu zosamalira khungu zomwe ziliarbutin, ndikofunika kuti muwerenge cholembera kuti muwone ngati α-arbutin kapena β-arbutin amagwiritsidwa ntchito.Ngakhale mankhwala onsewa amatha kukhala othandiza, α-arbutin nthawi zambiri amawonedwa ngati chisankho chapamwamba chifukwa cha kukhazikika kwake komanso mphamvu zake.

Ndikofunikiranso kuzindikira kuti kukhudzika kwapakhungu kumatha kusiyanasiyana.Anthu ena amatha kukhala ndi zotsatira zoyipa monga kuyabwa pakhungu kapena kufiira akamagwiritsa ntchito mankhwala okhala ndi arbutin.Monga momwe zilili ndi mankhwala aliwonse osamalira khungu, tikulimbikitsidwa kuyesa chigamba musanagwiritse ntchito pakhungu lalikulu komanso kukaonana ndi dermatologist ngati muli ndi nkhawa zokhudzana ndi zomwe zingachitike.

Pomaliza, onse α-arbutin ndi β-arbutin ndi ma glycosides a hydroquinone omwe amagwiritsidwa ntchito pakuwunikira kwawo pakhungu.Komabe, kuyika kwa α-arbutin kwa chomangira cha glycosidic pamalo a alpha kumapangitsa kuti ikhale yokhazikika komanso yosungunuka, ndikupangitsa kuti ikhale chisankho chokondedwa kwambiri pazinthu zosamalira khungu pofuna kuchepetsa hyperpigmentation ndikukhala ndi khungu lofananira.
