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

I-Beta-D-galactose pentaacetate yikhemikhali ephuma kwi-galactose, uhlobo lweswekile. Yenziwa yi-acetylating galactose enamaqela amahlanu e-acetyl. Olu tshintsho lunyusa uzinzo lwe-compound kwaye luvumela ukuba isetyenziswe kwiindlela ezahlukeneyo zekhemikhali kunye ne-biochemical. I-Beta-D-galactose pentaacetate isetyenziswa rhoqo njenge-arhente yokukhusela i-galactose kwiimpendulo ze-organic. Inceda ukuthintela iimpendulo ezingafunekiyo okanye iimpendulo ezingalindelekanga ngokufihla amaqela asabelayo e-galactose. Ukongeza, le compound ngamanye amaxesha isetyenziswa njenge-precursor okanye izinto zokuqala ekuhlanganiseni ezinye izinto ezivela kwi-galactose. Uhlobo lwayo lwe-acetylated luvumela ukuba kube lula ukulawulwa kunye nokuguqulwa kwemolekyuli ye-galactose kwiimpendulo ezilandelayo. Ngokubanzi, i-beta-D-galactose pentaacetate yikhemikhali eluncedo kuphando lweekhemikhali kunye nokuhlanganiswa okubonelela ngozinzo kunye nokuguquguquka kwiimpendulo ezinxulumene ne-galactose.

Ukusetyenziswa kunye nesiphumo

I-Beta-D-galactose pentaacetate, edla ngokubizwa ngokuba yi-galactose pentaacetate, sisiphumo se-galactose apho amaqela amahlanu e-acetyl anamathele kumaqela e-hydroxyl e-galactose. Olu tshintsho lweekhemikhali luphucula uzinzo lwe-compound kwaye lutshintsha iimpawu zayo zomzimba nezekhemikhali.

Isiphumo esiphambili kunye nokusetyenziswa kwe-beta-D-galactose pentaacetate kusekusetyenzisweni kwayo njengeqela elikhuselayo le-galactose kwi-organic synthesis. Amaqela akhuselayo lutshintsho lwexeshana olusetyenziselwa ukukhusela amaqela athile asebenzayo ngaphakathi kwi-molecule kwiimpendulo ezingafunekiyo ngexesha lokuguqulwa kweekhemikhali. Kwimeko ye-galactose, amaqela e-acetyl kwimo ye-pentaacetate asebenza njengezikhuselo zamaqela e-hydroxyl.

Ngokusebenzisa i-beta-D-galactose pentaacetate njengeqela elikhuselayo, iingcali zamachiza zinokukhetha ukulawula ezinye iindawo zemolekyuli ngaphandle kokutshintsha okanye ukuphazamisa amaqela e-hydroxyl. Oku kuguquguquka kuvumela ukwenziwa okulawulwayo nokuchanekileyo kwiindawo ezifana nekhemistri ye-carbohydrate, uphuhliso lwamayeza, kunye nokwenziwa kwemveliso yendalo.

Nje ukuba iimpendulo ezifunekayo zigqityiwe, amaqela e-acetyl anokuhlukaniswa ukuze kubuyiselwe amaqela okuqala e-hydroxyl e-galactose, kuphume imveliso efunekayo. Iindlela ezahlukeneyo, ezifana ne-hydrolysis eneemeko ezisisiseko okanye i-enzyme hydrolysis, zingasetyenziswa ukususa amaqela e-acetyl.
