Taw qhia

D-alanine yog chiral amino acid. D-alanine yog cov xim tsis muaj xim crystalline uas yog soluble hauv dej thiab acids. Nws yog acidic thiab alkaline thiab kuj ua raws li cov organic acid.

Txoj kev npaj ntawm D-alanine yog qhov yooj yim. Ib txoj kev npaj ntau yog tau los ntawm enzymatic catalysis ntawm cov tshuaj tiv thaiv chiral. D-alanine kuj tuaj yeem tau txais los ntawm chiral cais ntawm alanine.

Nws yog ib qho teeb meem dav dav uas yuav ua rau khaus qhov muag, ua pa, thiab tawv nqaij. Tshuaj tiv thaiv tsom iav, hnab looj tes thiab qhov ncauj qhov ntswg yuav tsum tau hnav thaum ua haujlwm kom muaj kev nyab xeeb.

Nov yog cov lus qhia luv luv rau cov khoom, kev siv, kev npaj thiab kev nyab xeeb ntawm D-alanine. Yog xav paub ntxiv, nrog rau cov ntaub ntawv tshuaj muaj feem xyuam lossis nrog tus kws tshaj lij.
