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

Beta-D-galactose pentaacetate, oo inta badan loo yaqaan galactose pentaacetate, waa nooc ka mid ah galactose kaas oo shan kooxood oo acetyl ah ay ku xiran yihiin kooxaha hydroxyl ee galactose.Wax ka beddelkan kiimikaad waxa uu wanaajiyaa xasilloonida xarunta oo beddelaa sifooyinka jidheed iyo kiimikaad.

Saamaynta asaasiga ah iyo codsiga beta-D-galactose pentaacetate waxay ku jirtaa ka faa'iidaysigeeda koox ilaalin ah galactose ee isku-dhafka organic.Kooxaha ilaalinaya waa wax ka beddel ku meel gaar ah oo loo isticmaalo in lagu ilaaliyo kooxo hawleed gaar ah oo ku dhex jira molecule ka falcelinta aan loo baahnayn inta lagu jiro isbeddelka kiimikada.Marka laga hadlayo galactose, kooxaha acetyl ee ku jira qaabka pentaacetate waxay u adeegaan gaashaanka difaaca kooxaha hydroxyl 

Iyagoo shaqaalaysiinaya beta-D-galactose pentaacetate koox ilaalin ahaan, farmashiyeyaashu waxay si xushmad leh u maamuli karaan gobollada kale ee molecule-ka iyagoon wax ka beddelin ama faragelin kooxaha hydroxyl.Kala duwanaanshiyahani wuxuu u oggolaanayaa in la xakameeyo oo si sax ah loogu sameeyo goobaha sida kimistariga karbohaydraytyada, horumarinta daroogada, iyo isku-dhafka alaabta dabiiciga ah.

Marka falcelinta la rabo la dhammeeyo, kooxaha acetyl waa la kala qaadi karaa si loo soo celiyo kooxihii asalka ahaa ee hydroxyl ee galactose, taasoo keenaysa badeecadii la rabay.Habab dhowr ah, sida hydrolysis oo leh xaalado aasaasiga ah ama hydrolysis enzymatic, ayaa la isticmaali karaa si looga saaro kooxaha acetyl.
