Ukusetyenziswa
I-ArbutinIkwiikhompawundi ze-hydroquinone glycoside. Igama layo lekhemikhali yi-4-Hydroquinone-alpha-D-glucopyranoside. Ifumaneka kwizityalo ezifana ne-bearberry kunye ne-bilberry, kwaye yinto esebenzayo yendalo ephumayo engenako ukurhawuzelelwa, engena-allergy kwaye ihambelana kakhulu neChemicalbook. Kukho amaqela amabini asebenzayo kwisakhiwo se-molecular se-arbutin: elinye liyi-glucose residue, kwaye elinye liqela le-phenolic hydroxyl. I-Alpha-arbutin ikwimeko yomzimba yomgubo omhlophe ukuya kongwevu olukhanyayo kwaye iyanyibilika emanzini nakwi-ethanol.
I-Alpha-arbutininefuthe elihle lokunyanga amanxeba abangelwa kukutsha kwe-ultraviolet, kwaye inefuthe elihle lokulwa nokuvuvukala, ukulungisa kunye nokwenza mhlophe. Inokuthintela ukuveliswa kunye nokugcinwa kwe-melanin kwaye isuse amabala okuguga kunye namabala.
Indlela yokwenza mhlophe ye-alpha-arbutin kukuthintela ngokuthe ngqo umsebenzi we-tyrosinase, ngaloo ndlela kunciphisa ukuveliswa kwe-melanin, endaweni yokufezekisa injongo yokunciphisa ukuveliswa kwe-melanin ngokuthintela ukukhula kweeseli okanye ukubonakaliswa kwe-gene ye-tyrosinase. Ekubeni i-alpha-arbutin iyinto esebenzayo nekhuselekileyo yokwenza mhlophe, iinkampani ezininzi ze-cosmetic ekhaya nakwamanye amazwe sele zisebenzise i-alpha-arbutin endaweni ye-beta-arbutin njengesongezelelo sokwenza mhlophe. I-Alpha-arbutin sisithako seekhemikhali. Njenge-arbutin, i-alpha-arbutin inokuthintela ukuveliswa kunye nokubekwa kwe-melanin kwaye isuse amabala obudala kunye namabala. Izifundo zibonise ukuba i-alpha-arbutin inokuthintela umsebenzi we-tyrosinase kumanqanaba aphantsi, kwaye isiphumo sayo sokuthintela kwi-tyrosinase singcono kunese-arbutin. I-Alpha-arbutin ingasetyenziswa njengearhente yokwenza mhlophe kwi-cosmetics.
