I-Alpha-Arbutin kanye ne-Beta-Arbutin yizithako ezimbili ezivamile ezimhlophe. Zinomehluko othile ngesakhiwo nezakhiwo, njengokulandelayo:
Isakhiwo:
Igama lekhemikhali le-α-arbutin yi-4-hydroxybenzaldehyde-D-glucoside, elakhiwe ngokuxhuma i-benzaldehyde nama-molecule e-glucose ngeqembu le-aldehyde neqembu le-hydroxyl. Igama lekhemikhali le-β-arbutin yi-β-D-glucoside ether benzaldehyde, elakhiwe nge-glucose ne-benzaldehyde molecule ngokuxhunywa kwe-glucose namaqembu e-aldehyde.
Ama-isomers abonakalayo:
I-Alpha arbutin: I-Alpha arbutin ingeye-D-isomer, okungukuthi, inemvelo engakwesokudla.
I-β-Arbutin ingeye-D-isomer noma ifomu elingasebenzi ngokubona.
Umphumela wokuba mhlophe:
I-Alpha Arbutin: I-Alpha Arbutin inomphumela onamandla omhlophe, ingavimbela umsebenzi we-tyrosinase, inciphise ukukhiqizwa kwe-melanin, ngaleyo ndlela inciphise umbala kanye nethoni yesikhumba sakusihlwa. I-Beta arbutin: I-Beta arbutin nayo inomphumela othile wokuba mhlophe, kodwa uma iqhathaniswa ne-alpha arbutin, umphumela wayo wokuba mhlophe ubuthakathaka.
Ukuzinza:
I-Alpha Arbutin:
I-Alpha arbutin inokusimama okuhle kumatrices anamanzi namafutha futhi ayithinteki kalula ukukhanya, ukushisa kanye nenani le-pH. Uma kuqhathaniswa ne-α-arbutin, i-β-arbutin ijwayele ukubola nokwehluleka ngaphansi kwezimo ezithile.
Sekukonke, kunomehluko phakathi kwe-α-arbutin ne-β-arbutin ngokwesakhiwo, ama-isomers abonakalayo, umphumela omhlophe nokuzinza. I-Alpha arbutin inomthelela omhlophe oqinile nokuzinza okuhle, kuyilapho i-beta arbutin inomphumela wobumhlophe obuthaka kanye nokuzinza okubi. Izithako eziqondile ezisetshenziswayo zincike ezidingweni kanye nemiphumela oyifunayo yomkhiqizo.
Ukunyibilika:
I-Alpha Arbutin: I-Alpha Arbutin inokunyibilika okuphezulu futhi ingancibilika kuzincibilikisi ezifana namanzi ne-ethanol. Ukunyibilika kwe-beta arbutin kuphansi, kubi kakhulu kune-alpha arbutin.
Ukuphepha:
I-Alpha arbutin ithathwa njengesithako esimhlophe esimhlophe, esingacasuli kancane esikhumbeni futhi ifanele abantu abanezinhlobo ezahlukene zesikhumba. I-Beta arbutin nayo iphephile uma kuqhathaniswa, kodwa kwezinye izimo ingase ibangele ukucasuka kwesikhumba noma ukungezwani komzimba, ikakhulukazi uma isetshenziswa ezindaweni ezigxilile kakhulu noma esikhumbeni esibucayi.
Emikhiqizweni yezimonyo neyokunakekelwa kwesikhumba, i-alpha ne-beta arbutin ivamise ukulebulwa ngokucacile njengezithako zefomula. Ngakho-ke, ungakwazi ukunquma ukuthi yiziphi izithako ezisetshenziswa emkhiqizweni ngokubheka uhlu lwesithako somkhiqizo noma ukubuza umkhiqizo noma umkhiqizi.
Kufanele kuqashelwe ukuthi noma ngabe i-alpha arbutin noma i-beta arbutin, ukuphepha nokusebenza kwayo kuncike kufomula yomkhiqizo ethile kanye nendlela yokusetshenziswa. Uma ukhetha imikhiqizo ongayisebenzisa, kungcono ukhethe imikhiqizo ehambisana nohlobo lwesikhumba sakho kanye nezidingo.
