Ukusetshenziswa
I-ArbutinIyingxenye yamakhemikhali e-hydroquinone glycoside. Igama layo lamakhemikhali yi-4-Hydroquinone-alpha-D-glucopyranoside. Itholakala ezitshalweni ezifana ne-bearberry ne-bilberry, futhi iyisithako esisebenzayo esisanda kuvela esimhlophe esingenakho ukucasuka, asinakho ukungezwani komzimba futhi sihambisana kakhulu ne-Chemicalbook. Kunezinhlobo ezimbili zamaqembu asebenzayo nesakhiwo esisebenzayo esakhiweni sama-molecule e-arbutin: elinye liyinsalela ye-glucose, kanti elinye liyiqembu le-phenolic hydroxyl. I-Alpha-arbutin isesimweni somzimba sempuphu emhlophe kuya kongwevu olukhanyayo futhi incibilika kakhulu emanzini nase-ethanol.
I-Alpha-arbutininomphumela omuhle wokwelapha ezibazini ezibangelwa ukusha kwe-ultraviolet, futhi inemiphumela emihle yokulwa nokuvuvukala, ukulungisa kanye nokwenza mhlophe. Ingavimbela ukukhiqizwa kanye nokufakwa kwe-melanin futhi isuse amabala okuguga nama-freckles.
Indlela yokwenza mhlophe ye-alpha-arbutin ukuvimbela ngqo umsebenzi we-tyrosinase, ngaleyo ndlela kuncishiswe ukukhiqizwa kwe-melanin, kunokufeza inhloso yokunciphisa ukukhiqizwa kwe-melanin ngokuvimbela ukukhula kwamaseli noma ukubonakaliswa kwe-gene ye-tyrosinase. Njengoba i-alpha-arbutin iyinto esebenzayo yokwenza mhlophe esebenza kahle futhi ephephile, izinkampani eziningi zezimonyo ekhaya nakwamanye amazwe sezivele zisebenzisa i-alpha-arbutin esikhundleni se-beta-arbutin njengesithako sokwenza mhlophe. I-Alpha-arbutin iyikhemikhali. Njenge-arbutin, i-alpha-arbutin ingavimbela ukukhiqizwa nokufakwa kwe-melanin futhi isuse amabala obudala namabala. Izifundo zikhombisile ukuthi i-alpha-arbutin ingavimbela umsebenzi we-tyrosinase ngamanani aphansi kakhulu, futhi umphumela wayo wokuvimbela ku-tyrosinase ungcono kunowe-arbutin. I-Alpha-arbutin ingasetshenziswa njenge-ejenti yokwenza mhlophe ezimonyweni.
