L-Valine
L-Valine 72-18-4 yog dawb crystals lossis crystalline hmoov, nrog ethanol aqueous tov hnyav huv tib neeg rau cov xim tsis muaj xim lossis scaly crystallization.Tsis muaj ntxhiab tsw, muaj qhov tshwj xeeb iab.Melting point ntawm txog 315 ° C.
Function & Applications:L-valine yog ib qho ntawm yim yam tseem ceeb amino acids rau tib neeg lub cev, uas yuav siv tau nyob rau hauv kev npaj ntawm compound amino acid infusions, synthesis polypeptide tshuaj thiab zaub mov antioxidant thiab lwm yam. Nws yog dav siv nyob rau hauv cov ntshav-hlwb barrier, hepatic coma, ntev. daim siab cirrhosis, thiab kho lub raum tsis ua hauj lwm, inborn yuam kev ntawm metabolism ntawm kev noj haus kev kho mob, sepsis, thiab postoperative kev kho mob ntawm cov neeg mob ntshav qab zib, raws li zoo raws li nyob rau hauv cov tshuaj ua kom cov kev kho mob ntawm phais qhov txhab thiab nyob rau hauv kev noj haus kev pab txhawb nqa ntawm cov neeg mob cancer.Tsis tas li ntawd, nws kuj yog siv rau hauv kev npaj ntawm infusions siab nyob rau hauv branched-chain amino acids (xws li 3H infusion, thiab lwm yam) thiab lub qhov ncauj kua (xws li daim siab - ib tug qhuav syrup, thiab lwm yam.).Kev siv hauv cov khoom noj khoom haus fortifier, zaub mov tsw enhancer thiab tshuaj tua kab ua liaj ua teb kuj nrov.
