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

I-Beta-D-galactose pentaacetate iyinhlanganisela yamakhemikhali etholakala ku-galactose, uhlobo lukashukela.Yakhiwa yi-acetylating galactose enamaqembu amahlanu e-acetyl.Lokhu kuguqulwa kukhulisa ukuqina kwenhlanganisela futhi kuyivumela ukuthi isetshenziswe kumakhemikhali ahlukahlukene kanye nezinhlelo zokusebenza zamakhemikhali ezinto eziphilayo.I-Beta-D-galactose pentaacetate ivame ukusetshenziswa njenge-ejenti evikelayo ye-galactose ekuphenduleni kwezinto eziphilayo.Isiza ukuvimbela ukusabela okungafuneki noma ukusabela okusemaceleni ngokuvala amaqembu asebenzayo e-galactose.Ukwengeza, le nhlanganisela ngezinye izikhathi isetshenziswa njengesandulela noma into yokuqala ekuhlanganisweni kokunye okuphuma ku-galactose.Ifomu layo le-acetylated livumela ukuguqulwa nokuguqulwa kwe-molecule ye-galactose ekuphenduleni okulandelayo.Sekukonke, i-beta-D-galactose pentaacetate iyinhlanganisela ewusizo ocwaningweni lwamakhemikhali kanye nokuhlanganiswa okunikeza ukuzinza nokuguquguquka kokusabela okuhlobene ne-galactose.

Isicelo kanye Nomphumela

I-Beta-D-galactose pentaacetate, evame ukubizwa ngokuthi i-galactose pentaacetate, iphuma ku-galactose lapho amaqembu amahlanu e-acetyl exhunywe emaqenjini e-hydroxyl e-galactose.Lokhu kuguqulwa kwamakhemikhali kuthuthukisa ukuzinza kwenhlanganisela futhi kushintsha izici zayo ezibonakalayo namakhemikhali.

Umphumela oyinhloko kanye nokusetshenziswa kwe-beta-D-galactose pentaacetate kusekusetshenzisweni kwayo njengeqembu elivikela i-galactose ku-organic synthesis.Amaqembu okuvikela ayizinguquko zesikhashana ezisetshenziselwa ukuvikela amaqembu athile asebenzayo ngaphakathi kwe-molecule ekuphenduleni okungafunwa phakathi nokuguqulwa kwamakhemikhali.Endabeni ye-galactose, amaqembu e-acetyl efomini le-pentaacetate asebenza njengezihlangu zokuvikela amaqembu e-hydroxyl.

Ngokusebenzisa i-beta-D-galactose pentaacetate njengeqembu elivikelayo, osokhemisi bangakwazi ukukhetha ngokukhetha ezinye izifunda ze-molecule ngaphandle kokushintsha noma ukuphazamisa amaqembu e-hydroxyl.Lokhu kuguquguquka kuvumela ukuhlanganiswa okulawulwayo nokunembayo emikhakheni efana ne-carbohydrate chemistry, ukuthuthukiswa kwezidakamizwa, kanye nokuhlanganiswa kwemikhiqizo yemvelo.

Uma ukusabela okufunayo sekuqediwe, amaqembu e-acetyl angahlukaniswa ukuze kubuyiselwe amaqembu okuqala e-hydroxyl ye-galactose, anikeze umkhiqizo owufunayo.Izindlela ezimbalwa, ezifana ne-hydrolysis enezimo eziyisisekelo noma i-enzymatic hydrolysis, zingasetshenziswa ukususa amaqembu e-acetyl.
