ʻO ka ʻokoʻa ma waena o alpha arbutin a me beta arbutin

Alpha-Arbutin a ʻo Beta-Arbutin ʻelua mau mea keʻokeʻo maʻamau. Loaʻa iā lākou kekahi mau ʻokoʻa ma ke ʻano a me nā waiwai, penei:
Kapili:
ʻO ka inoa kemika o α-arbutin ʻo 4-hydroxybenzaldehyde-D-glucoside, i hana ʻia ma ka hoʻohui ʻana i nā molekala benzaldehyde a me ka glucose ma o ka hui aldehyde a me ka hui hydroxyl. ʻO ka inoa kemika o β-arbutin ʻo β-D-glucoside ether benzaldehyde, i hana ʻia mai ka glucose a me nā molekala benzaldehyde ma o ka pilina o nā pūʻulu glucose a me aldehyde.

ʻO nā isomers opi:
Alpha arbutin: No ka D-isomer ka Alpha arbutin, ʻo ia hoʻi, he ʻano lima ʻākau kona.
Aia ka β-Arbutin i ka D-isomer a i ʻole ke ʻano hana non-optically.

Ka hopena keʻokeʻo:
ʻO Alpha Arbutin: He hopena keʻokeʻo ikaika ka Alpha Arbutin, hiki ke kāohi i ka hana o tyrosinase, hoʻemi i ka hana ʻana o ka melanin, a laila e hōʻemi ana i ka pigmentation a me ka ʻili o ke ahiahi. Beta arbutin: Loaʻa i ka Beta arbutin kekahi hopena keʻokeʻo, akā ke hoʻohālikelike ʻia me alpha arbutin, ʻoi aku ka nāwaliwali o kona hopena keʻokeʻo.

Paʻa:
Alpha Arbutin:
He kūpaʻa maikaʻi ka Alpha arbutin i loko o nā matrices wai a me ka ʻaila a ʻaʻole maʻalahi i ka maʻalahi o ka māmā, ka wela a me ka waiwai pH. Ke hoʻohālikelike ʻia me ka α-arbutin, ʻoi aku ka maʻalahi o ka β-arbutin i ka decomposition a me ka hemahema ma lalo o kekahi mau kūlana.
Ma keʻano holoʻokoʻa, aia nā ʻokoʻa ma waena o ka α-arbutin a me ka β-arbutin ma ke ʻano o ke ʻano, nā isomers optical, ka hopena keʻokeʻo a me ke kūpaʻa. Loaʻa ka Alpha arbutin i kahi hopena keʻokeʻo ikaika a me ka paʻa maikaʻi, ʻoiai ʻo ka beta arbutin he hopena keʻokeʻo nāwaliwali a me ka maikaʻi ʻole. ʻO nā mea kikoʻī i hoʻohana ʻia ma muli o nā pono a me nā hopena i makemake ʻia o ka huahana.

Hiki ke hoʻoheheʻe:
Alpha Arbutin: He kiʻekiʻe ka solubility ʻo Alpha Arbutin a hiki ke hoʻoheheʻe ʻia i nā solvents e like me ka wai a me ka ethanol. He haʻahaʻa ka solubility o ka beta arbutin, ʻoi aku ka ʻino ma mua o ka alpha arbutin.

Palekana:
Manaʻo ʻia ʻo Alpha arbutin he mea hoʻomaʻemaʻe keʻokeʻo palekana, ʻoi aku ka hoʻonāukiuki i ka ʻili a kūpono i nā poʻe me nā ʻano ʻili like ʻole. He palekana nō hoʻi ka Beta arbutin, akā i kekahi mau hihia, hiki ke hōʻeha i ka ʻili a i ʻole ka maʻi maʻi, ʻoi aku ka maikaʻi ke hoʻohana ʻia i ka ʻili kiʻekiʻe a i ʻole ka ʻili paʻakikī.
I loko o nā mea hoʻonaninani a me nā huahana mālama ʻili, ʻike pinepine ʻia ka alpha a me ka beta arbutin ma ke ʻano he mea hoʻohui. No laila, hiki iā ʻoe ke hoʻoholo i nā mea i hoʻohana ʻia i loko o kahi huahana ma ka nānā ʻana i ka papa inoa o ka huahana a i ʻole ke nīnau ʻana i ka brand a mea hana paha.

Pono e hoʻomaopopo ʻia inā he alpha arbutin a i ʻole beta arbutin, ʻo kona palekana a me ka pono e hilinaʻi ʻia ma ke ʻano huahana kikoʻī a me ke ʻano o ka hoʻohana. Ke koho ʻana i nā huahana e hoʻohana ai, ʻoi aku ka maikaʻi o ke koho ʻana i nā huahana i kūpono i kou ʻano ʻili a me nā pono.
