Beta-D-Galactose pentaacetate CAS:114162-64-0

ʻO ka Beta-D-galactose pentaacetate, i kapa pinepine ʻia ʻo galactose pentaacetate, he hua ia o ka galactose kahi i hoʻopili ʻia ai nā hui acetyl ʻelima i nā hui hydroxyl o ka galactose. Hoʻonui kēia hoʻololi kemika i ke kūpaʻa o ka hui a hoʻololi i kona mau waiwai kino a me ke kemika.

ʻO ka hopena mua a me ka hoʻohana ʻana o ka beta-D-galactose pentaacetate e waiho ana i kona hoʻohana ʻana ma ke ʻano he hui pale no ka galactose i ka synthesis organik. ʻO nā hui pale he mau hoʻololi manawa pōkole i hoʻohana ʻia e pale i nā hui hana kikoʻī i loko o kahi mole mai nā hopena i makemake ʻole ʻia i ka wā o nā hoʻololi kemika. I ke ʻano o ka galactose, lawelawe nā hui acetyl i ke ʻano pentaacetate ma ke ʻano he pale pale no nā hui hydroxyl. 

Ma ka hoʻohana ʻana i ka beta-D-galactose pentaacetate ma ke ʻano he hui pale, hiki i nā kemika ke hoʻoponopono koho i nā ʻāpana ʻē aʻe o ka mole me ka ʻole o ka hoʻololi a i ʻole ke keakea ʻana i nā hui hydroxyl. ʻAe kēia versatility no ka synthesis i kāohi ʻia a pololei hoʻi i nā kahua e like me ke kemika carbohydrate, ka hoʻomohala ʻana i nā lāʻau lapaʻau, a me ka synthesis huahana kūlohelohe.

Ke pau nā hopena i makemake ʻia, hiki ke ʻoki ʻia nā hui acetyl e hoʻihoʻi i nā hui hydroxyl mua o ka galactose, e loaʻa ai ka huahana i makemake ʻia. Hiki ke hoʻohana ʻia kekahi mau ʻano hana, e like me ka hydrolysis me nā kūlana kumu a i ʻole ka hydrolysis enzymatic, e wehe i nā hui acetyl.
