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

Beta-D-galactose pentaacetate, eo hangata e bitsoang galactose pentaacetate, e tsoa ho galactose moo lihlopha tse hlano tsa acetyl li hoketsoeng ho lihlopha tsa hydroxyl tsa galactose.Phetoho ena ea lik'hemik'hale e matlafatsa botsitso ba motsoako 'me e fetola litšobotsi tsa eona tsa' mele le tsa lik'hemik'hale.

Phello ea mantlha le ts'ebeliso ea beta-D-galactose pentaacetate li teng ts'ebelisong ea eona e le sehlopha se sireletsang galactose ho organic synthesis.Lihlopha tse sireletsang ke liphetoho tsa nakoana tse sebelisetsoang ho sireletsa lihlopha tse itseng tse sebetsang ka har'a molek'hule ho tloha karabelong e sa batleheng nakong ea liphetoho tsa lik'hemik'hale.Tabeng ea galactose, lihlopha tsa acetyl ka mokhoa oa pentaacetate li sebetsa e le lithebe tse sireletsang lihlopha tsa hydroxyl. 

Ka ho sebelisa beta-D-galactose pentaacetate e le sehlopha se sireletsang, litsebi tsa k'hemistri li ka khetha libaka tse ling tsa molek'hule ntle le ho fetola kapa ho kena-kenana le lihlopha tsa hydroxyl.Mokhoa ona oa ho feto-fetoha o lumella hore ho be le mokhoa o laoloang le o nepahetseng mafapheng a kang k'hemistri ea lik'habohaedreite, nts'etsopele ea lithethefatsi, le motsoako oa lihlahisoa tsa tlhaho.

Hang ha maikutlo a lakatsehang a phethiloe, lihlopha tsa acetyl li ka aroloa ho tsosolosa lihlopha tsa pele tsa hydroxyl tsa galactose, ho fana ka sehlahisoa se lakatsehang.Mekhoa e mengata, joalo ka hydrolysis e nang le maemo a mantlha kapa enzymatic hydrolysis, e ka sebelisoa ho tlosa lihlopha tsa acetyl.
