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

Beta-D-galactose pentaacetate, eo hangata e bitsoang galactose pentaacetate, ke motsoako oa galactose moo lihlopha tse hlano tsa acetyl li hoketsoeng lihlopheng tsa hydroxyl tsa galactose. Phetoho ena ea lik'hemik'hale e ntlafatsa botsitso ba motsoako 'me e fetola litšobotsi tsa oona tsa' mele le tsa lik'hemik'hale.

Tšusumetso ea mantlha le ts'ebeliso ea beta-D-galactose pentaacetate li holim'a ts'ebeliso ea eona e le sehlopha se sireletsang bakeng sa galactose ka har'a motsoako oa lintho tse phelang. Lihlopha tse sireletsang ke liphetoho tsa nakoana tse sebelisetsoang ho sireletsa lihlopha tse itseng tse sebetsang ka har'a molek'hule ho tsoa liketsong tse sa batleheng nakong ea liphetoho tsa lik'hemik'hale. Tabeng ea galactose, lihlopha tsa acetyl ka sebopeho sa pentaacetate li sebetsa e le lithebe tse sireletsang bakeng sa lihlopha tsa hydroxyl. 

Ka ho sebelisa beta-D-galactose pentaacetate e le sehlopha se sireletsang, litsebi tsa lik'hemistri li ka laola libaka tse ling tsa molek'hule ka boikhethelo ntle le ho fetola kapa ho sitisa lihlopha tsa hydroxyl. Ho feto-fetoha hona ho lumella tlhahiso e laoloang le e nepahetseng masimong a kang k'hemistri ea lik'habohaedreite, nts'etsopele ea lithethefatsi le tlhahiso ea lihlahisoa tsa tlhaho.

Hang ha dikarabelo tse lakatsehang di phethetswe, dihlopha tsa acetyl di ka kgaolwa ho tsosolosa dihlopha tsa pele tsa hydroxyl tsa galactose, ho hlahisa sehlahiswa se lakatsehang. Mekhoa e mmalwa, jwalo ka hydrolysis e nang le maemo a motheo kapa enzyme hydrolysis, e ka sebediswa ho tlosa dihlopha tsa acetyl.
