Phapang lipakeng tsa alpha arbutin le beta arbutin

Alpha-Arbutin le Beta-Arbutin ke lintho tse peli tse tloaelehileng tse soeufatsang. Ba na le liphapang ka sebopeho le thepa, ka tsela e latelang:
Sebopeho:
Lebitso la lik'hemik'hale la α-arbutin ke 4-hydroxybenzaldehyde-D-glucoside, e entsoeng ka ho hokahanya limolek'hule tsa benzaldehyde le glucose ka sehlopha sa aldehyde le sehlopha sa hydroxyl. Lebitso la lik'hemik'hale la β-arbutin ke β-D-glucoside ether benzaldehyde, e entsoeng ka limolek'hule tsa glucose le benzaldehyde ka ho hokahanya ha glucose le lihlopha tsa aldehyde.

Li-isomers tsa mahlo:
Alpha arbutin: Alpha arbutin ke ea D-isomer, ke hore, e na le tlhaho e letsohong le letona.
β-Arbutin ke ea mofuta oa D-isomer kapa o sa sebetseng hantle.

Matla a ho soeufala:
Alpha Arbutin: Alpha Arbutin e na le phello e matla ea ho soeufala, e ka thibela mosebetsi oa tyrosinase, ea fokotsa tlhahiso ea melanin, kahoo e fokotsa pigmentation le molumo oa letlalo la mantsiboea. Beta arbutin: Beta arbutin le eona e na le phello e itseng ea bosoeu, empa ha e bapisoa le alpha arbutin, phello ea eona e tšoeu e fokola.

Botsitso:
Alpha Arbutin:
Alpha arbutin e na le botsitso bo botle matrices a metsi le mafura 'me ha e amehe habonolo ke khanya, mocheso le pH ea boleng. Ha e bapisoa le α-arbutin, β-arbutin e atisa ho bola le ho hlōleha tlas'a maemo a itseng.
Ka kakaretso, ho na le phapang pakeng tsa α-arbutin le β-arbutin mabapi le sebopeho, li-isomers tsa optical, phello e tšoeu le botsitso. Alpha arbutin e na le phello e matla ea bosoeu le botsitso bo botle, athe beta arbutin e na le phello e fokolang e fokolang le botsitso bo fokolang. Lisebelisoa tse nepahetseng tse sebelisoang li itšetlehile ka litlhoko le liphello tse lakatsehang tsa sehlahisoa.

Sollubility:
Alpha Arbutin: Alpha Arbutin e na le solubility e phahameng 'me e ka qhibiliha ka har'a metsoako e kang metsi le ethanol. Thesolubility ea beta arbutin e batla e le tlase, e mpe hanyane ho feta alpha arbutin.

Tšireletseho:
Alpha arbutin e nkoa e le motsoako o sireletsehileng oa ho soeufala, o sa halefiseng letlalo ebile o loketse batho ba nang le mefuta e sa tšoaneng ea letlalo. Beta arbutin le eona e batla e bolokehile, empa maemong a mang e ka baka ho teneha ha letlalo kapa ho hanana le lintho tse itseng, haholo ha e sebelisoa maemong a mangata haholo kapa letlalong le bonolo.
Ho litlolo le lihlahisoa tsa tlhokomelo ea letlalo, alpha le beta arbutin hangata li ngotsoe ka ho hlaka e le metsoako ea foromo. Ka hona, o ka tseba hore na ke metsoako efe e sebelisoang sehlahisoa ka ho sheba lenane la motsoako oa sehlahisoa kapa ho botsa lebitso kapa moetsi.

Hoa lokela ho hlokomeloa hore hore na ke alpha arbutin kapa beta arbutin, polokeho le katleho ea eona li itšetlehile ka mokhoa o khethehileng oa sehlahisoa le mokhoa oa tšebeliso. Ha u khetha lihlahisoa tseo u ka li sebelisang, ho molemo ho khetha lihlahisoa tse lumellanang le mofuta oa letlalo la hao le litlhoko tsa hau.
