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

Beta-D-galactose pentaacetate, feem ntau hu ua galactose pentaacetate, yog ib qho derivative ntawm galactose uas tsib pawg acetyl txuas nrog cov hydroxyl pawg ntawm galactose. Qhov kev hloov pauv tshuaj no ua rau cov tshuaj ruaj khov thiab hloov nws cov khoom siv lub cev thiab tshuaj.

Qhov cuam tshuam tseem ceeb thiab kev siv ntawm beta-D-galactose pentaacetate yog nws siv ua pawg tiv thaiv rau galactose hauv kev tsim cov organic. Cov pawg tiv thaiv yog cov kev hloov pauv ib ntus uas siv los tiv thaiv cov pab pawg ua haujlwm tshwj xeeb hauv ib lub molecule los ntawm cov tshuaj tiv thaiv tsis xav tau thaum lub sijhawm hloov pauv tshuaj. Hauv cov ntaub ntawv ntawm galactose, cov pab pawg acetyl hauv daim ntawv pentaacetate ua haujlwm ua cov ntaub thaiv rau cov pab pawg hydroxyl. 

Los ntawm kev siv beta-D-galactose pentaacetate ua pawg tiv thaiv, cov kws tshuaj tuaj yeem xaiv lwm thaj chaw ntawm lub molecule yam tsis hloov pauv lossis cuam tshuam nrog cov pab pawg hydroxyl. Qhov kev hloov pauv no tso cai rau kev tswj hwm thiab meej synthesis hauv cov teb xws li carbohydrate chemistry, kev tsim tshuaj, thiab kev tsim cov khoom ntuj.

Thaum cov tshuaj tiv thaiv xav tau tiav lawm, cov pawg acetyl tuaj yeem raug txiav kom rov qab tau cov pawg hydroxyl qub ntawm galactose, ua rau cov khoom xav tau. Muaj ntau txoj hauv kev, xws li hydrolysis nrog cov xwm txheej yooj yim lossis enzymatic hydrolysis, tuaj yeem siv los tshem tawm cov pawg acetyl.
