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

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

I-Beta-D-galactose pentaacetate yikhemikhali ephuma kwigalactose, uhlobo lweswekile.Yenziwe nge-acetylating galactose kunye namaqela amahlanu e-acetyl.Olu hlengahlengiso lukhulisa uzinzo lwekhompawundi kwaye luvumela ukuba lusetyenziswe kwizicelo ezahlukeneyo zeekhemikhali kunye ne-biochemical.I-Beta-D-galactose pentaacetate isetyenziswa ngokuqhelekileyo njenge-agent ekhuselayo ye-galactose kwi-organic reactions.Inceda ukuthintela ukuphendulwa okungafunekiyo okanye ukuphendulwa kwecala ngokufihla amaqela asebenzayo e-galactose.Ukongezelela, le khompawundi ngamanye amaxesha isetyenziswa njenge-precursor okanye i-start material in synthesis of other galactose derivatives.Ifom yayo ye-acetylated ivumela ukuguqulwa lula kunye nokuguqulwa kwe-molecule ye-galactose kwiimpendulo ezilandelayo.Kuko konke, i-beta-D-galactose pentaacetate iyikhompawundi eluncedo kuphando lweekhemikhali kunye nokudibanisa okubonelela ukuzinza kunye nokuguquguquka kweempendulo ezinxulumene ne-galactose.

Isicelo kunye nesiphumo

I-Beta-D-galactose pentaacetate, edla ngokubizwa ngokuba yi-galactose pentaacetate, iphuma kwigalactose apho amaqela amahlanu e-acetyl adityaniswe kumaqela e-hydroxyl egalactose.Olu tshintsho lwekhemikhali luphucula uzinzo lwekhompawundi kwaye luguqula iimpawu zalo zomzimba kunye neekhemikhali.

Isiphumo sokuqala kunye nokusetyenziswa kwe-beta-D-galactose pentaacetate ilele ekusebenziseni kwayo njengeqela elikhuselayo le-galactose kwi-organic synthesis.Amaqela akhuselayo lutshintsho lwexeshana olusetyenziselwa ukukhusela amaqela athile asebenzayo ngaphakathi kwemolekyuli ekuphenduleni okungafunekiyo ngexesha lokuguqulwa kweekhemikhali.Kwimeko ye-galactose, amaqela e-acetyl kwifom ye-pentaacetate asebenza njengezikhuselo zokukhusela kumaqela e-hydroxyl.

Ngokusebenzisa i-beta-D-galactose pentaacetate njengeqela elikhuselayo, iikhemisti zinokukhetha ngokukhetha ezinye iindawo ze-molecule ngaphandle kokuguqula okanye ukuphazamisa amaqela e-hydroxyl.Oku kuguquguquka kuvumela ulungelelwaniso olulawulwayo noluchanekileyo kwiinkalo ezifana nekhemistri yecarbohydrate, uphuhliso lwamachiza, kunye nokuhlanganiswa kwemveliso yendalo.

Nje ukuba iimpendulo ezinqwenelekayo zigqityiwe, amaqela e-acetyl anokwahlulwa ukuze abuyisele amaqela e-hydroxyl oqobo egalactose, anike imveliso efunwayo.Iindlela ezininzi, ezifana ne-hydrolysis eneemeko ezisisiseko okanye i-enzymatic hydrolysis, zinokuqeshwa ukususa amaqela e-acetyl.
