Taw qhia

L-leucine yog ib qho amino acid uas yog ib qho ntawm lub tsev thaiv cov proteins. Nws yog xim tsis muaj xim, crystalline khoom uas yog soluble hauv dej.

 

Muaj ob txoj hauv kev tseem ceeb rau kev npaj ntawm L-leucine: natural method thiab chemical synthesis method. Cov txheej txheem ntuj feem ntau yog tsim los ntawm cov txheej txheem fermentation ntawm cov kab mob, xws li cov kab mob. Cov txheej txheem tshuaj synthesis yog npaj los ntawm cov txheej txheem ntawm cov organic synthesis.

 

Cov ntaub ntawv kev nyab xeeb ntawm L-Leucine: L-Leucine muaj kev nyab xeeb feem ntau. Kev noj ntau dhau yuav ua rau mob plab hnyuv, raws plab, thiab lwm yam tsos mob. Rau cov neeg uas muaj lub raum tsis txaus lossis metabolic abnormality, yuav tsum tau saib xyuas kom tsis txhob noj ntau dhau.
