Taw qhia

DL-Threonine yog ib qho tsis tseem ceeb amino acid, uas yog tau los ntawm kev sib txuas ntawm threonine catalyzed los ntawm soybean soybean enzyme. Nws yog ib tug dawb crystalline hmoov nrog ib tug qab zib saj uas dissolves nyob rau hauv dej. DL-threonine muaj ob chav phototropic xwm uas tuaj yeem tig lub teeb, thiab nws muaj ob isomers ntawm D-threonine thiab L-threonine, uas yog hu ua DL-threonine.

 

Txoj kev npaj ntawm DL-threonine feem ntau yog los ntawm enzymatic synthesis. Soybean soybean enzyme catalyzes cov synthesis ntawm DL-threonine, ob reactants ntawm D-threonine thiab L-threonine. Txoj kev no yog qhov ua tau zoo, ib puag ncig tus phooj ywg, tsis tas yuav siv cov kuab tshuaj organic, thiab muaj txiaj ntsig zoo thiab purity.

 

DL-Threonine kuj muaj kev nyab xeeb nyob rau hauv kev siv dav dav.
