Itandukaniro hagati ya α-arbutin na β-arbutin

α-arbutinna β-arbutine nibintu bibiri bifitanye isano ya hafi yimiti ikoreshwa mubicuruzwa byuruhu kubitera uruhu no kumurika.Mugihe basangiye imiterere yibanze hamwe nuburyo bwibikorwa, hariho itandukaniro rito hagati yibi byombi bishobora kugira ingaruka kubikorwa byabo n'ingaruka zishobora guterwa.

Mu buryo bwubaka, byombi α-arbutin na β-arbutine ni glycoside ya hydroquinone, bivuze ko bafite molekile ya glucose ifatanye na molekile ya hydroquinone.Ihuza ryimiterere ryemerera ibice byombi kubuza enzyme tyrosinase, igira uruhare mubikorwa bya melanin.Muguhagarika tyrosinase, ibyo bikoresho birashobora gufasha kugabanya umusaruro wa melanin, biganisha ku ruhu rworoshye ndetse ndetse rukanagira uruhu.

Itandukaniro ryibanze hagati ya α-arbutin na β-arbutin riri mumwanya wubusabane bwa glycosidique hagati ya glucose na hydroquinone moieties:

α-arbutin: Muri α-arbutin, umurunga wa glycosidique ufatanye na alfa ya mpeta ya hydroquinone.Iyi myanya yizera ko izamura ituze no gukemuka kwa α-arbutin, bigatuma ikora neza mugukoresha uruhu.Inkunga ya glycosidique nayo igabanya ubushobozi bwa okiside ya hydroquinone, ishobora gutuma habaho ibice byijimye birwanya ingaruka zifuza uruhu.

β-arbutin: Muri β-arbutin, umurunga wa glycosidique ufatanye na beta umwanya wa hydroquinone.Mugihe β-arbutine nayo ifite akamaro mukurinda tyrosinase, irashobora kuba idahagaze neza kuruta α-arbutine kandi ikunda guhura na okiside.Iyi okiside irashobora gutuma habaho ibara ryijimye ridakenewe cyane kumurika uruhu.

Bitewe no gukomera kwinshi no gukemuka, α-arbutin ikunze gufatwa nkuburyo bwiza kandi bwatoranijwe muburyo bwo kuvura uruhu.Byizerwa gutanga ibisubizo byiza-byorohereza uruhu kandi ntibishobora gutera ibara cyangwa ingaruka zitifuzwa.

Iyo usuzumye ibicuruzwa bivura uruhu birimoarbutin, ni ngombwa gusoma ikirango kugirango umenye niba α-arbutin cyangwa β-arbutin ikoreshwa.Mugihe ibyo bice byombi bishobora kuba ingirakamaro, α-arbutin muri rusange ifatwa nkuguhitamo gusumba kubera imbaraga zayo zongerewe imbaraga.

Ni ngombwa kandi kumenya ko ibyiyumvo byuruhu byihariye bishobora gutandukana.Abantu bamwe bashobora guhura ningaruka nko kurakara kuruhu cyangwa gutukura mugihe bakoresha ibicuruzwa birimo arbutine.Kimwe nibindi bikoresho byose byita ku ruhu, birasabwa gukora ibizamini mbere yo gukoresha ibicuruzwa ahantu hanini h'uruhu no kugisha inama umuganga w’impu niba ufite impungenge zijyanye n’ingaruka zishobora guterwa.

Mu gusoza, byombi α-arbutin na β-arbutine ni glycoside ya hydroquinone ikoreshwa mu ngaruka zabyo zo koroshya uruhu.Ariko, α-arbutin ihagaze ya glycosidic ihuza umwanya wa alfa itanga ituze ryinshi no gukemuka, bigatuma ihitamo neza kubicuruzwa byuruhu bigamije kugabanya hyperpigmentation no kugera kumubiri wuruhu.
