Kusiyana pakati pa alpha arbutin ndi beta arbutin

Alpha-Arbutin ndi Beta-Arbutin ndi zinthu ziwiri zodziwika bwino zoyera. Iwo ali ndi zosiyana mu kapangidwe ndi katundu, motere:
Kapangidwe:
Dzina lamankhwala la α-arbutin ndi 4-hydroxybenzaldehyde-D-glucoside, lomwe limapangidwa polumikiza benzaldehyde ndi mamolekyu a glucose kudzera mu gulu la aldehyde ndi gulu la hydroxyl. Dzina lamankhwala la β-arbutin ndi β-D-glucoside ether benzaldehyde, lomwe limapangidwa kuchokera ku glucose ndi benzaldehyde mamolekyulu kudzera mu kulumikizana kwa glucose ndi magulu a aldehyde.

Ma isomers a kuwala:
Alpha arbutin: Alpha arbutin ndi wa D-isomer, ndiye kuti, ili ndi chikhalidwe chakumanja.
β-Arbutin ndi ya D-isomer kapena mawonekedwe osawoneka bwino.

Whitening effect:
Alpha Arbutin: Alpha Arbutin ali ndi mphamvu yoyera yoyera, amatha kulepheretsa ntchito ya tyrosinase, kuchepetsa kupanga melanin, potero amachepetsa pigmentation ndi khungu lamadzulo. Beta arbutin: Beta arbutin ilinso ndi kuyera kwina, koma poyerekeza ndi alpha arbutin, kuyera kwake kumakhala kochepa.

Kukhazikika:
Alpha Arbutin:
Alpha arbutin ali ndi kukhazikika kwabwino mu matrices amadzi ndi mafuta ndipo samakhudzidwa mosavuta ndi kuwala, kutentha ndi pH mtengo. Poyerekeza ndi α-arbutin, β-arbutin imakonda kuwonongeka ndi kulephera pansi pazifukwa zina.
Ponseponse, pali kusiyana pakati pa α-arbutin ndi β-arbutin potengera kapangidwe kake, ma isomer owoneka bwino, kuyera komanso kukhazikika. Alpha arbutin imakhala ndi mphamvu yoyera komanso yokhazikika, pomwe beta arbutin imakhala ndi zofooka zochepa zoyera komanso zosakhazikika. Zosakaniza zenizeni zomwe zimagwiritsidwa ntchito zimadalira zosowa ndi zotsatira zomwe zimafunidwa.

Kusungunuka:
Alpha Arbutin: Alpha Arbutin ali ndi kusungunuka kwakukulu ndipo amatha kusungunuka mu zosungunulira monga madzi ndi ethanol. Kusungunuka kwa beta arbutin ndikotsika, koyipa pang'ono kuposa alpha arbutin.

Chitetezo:
Alpha arbutin amaonedwa kuti ndi chotetezera choyera choyera, chosakwiyitsa khungu komanso choyenera kwa anthu omwe ali ndi mitundu yosiyanasiyana ya khungu. Beta arbutin nayonso ndiyotetezeka, koma nthawi zina imatha kuyambitsa kuyabwa kapena kuyabwa, makamaka ikagwiritsidwa ntchito kwambiri kapena pakhungu.
Mu zodzoladzola ndi zosamalira khungu, alpha ndi beta arbutin nthawi zambiri amalembedwa momveka bwino ngati zosakaniza mu fomula. Choncho, mukhoza kudziwa zomwe zimagwiritsidwa ntchito popanga mankhwala poyang'ana mndandanda wazinthu zomwe zimagwiritsidwa ntchito kapena kufunsa mtundu kapena wopanga.

Zindikirani kuti kaya ndi alpha arbutin kapena beta arbutin, chitetezo chake ndi mphamvu zake zimadalira mtundu wa mankhwala ndi njira yogwiritsira ntchito. Posankha mankhwala oti mugwiritse ntchito, ndi bwino kusankha zinthu zomwe zimagwirizana ndi mtundu wa khungu lanu ndi zosowa zanu.
