Mawu Oyamba

D-alanine ndi chiral amino acid. D-alanine ndi cholimba cha crystalline chopanda mtundu chomwe chimasungunuka m'madzi ndi ma acid. Ndi acidic komanso zamchere komanso zimakhala ngati organic acid.

 

Njira yokonzekera D-alanine ndiyosavuta. Njira yokonzekera yodziwika bwino imapezedwa ndi enzymatic catalysis of chiral reactions. D-alanine imathanso kupezeka mwa chiral kudzipatula kwa alanine.

Ndi mankhwala owopsa omwe angayambitse kuyabwa m'maso, kupuma komanso khungu. Magalasi otetezera mankhwala, magolovesi ndi masks ayenera kuvala panthawi yogwira ntchito kuti ateteze chitetezo.

 

Pano pali chidziwitso chachidule cha katundu, ntchito, kukonzekera ndi chitetezo cha D-alanine. Kuti mumve zambiri, funsani mabuku okhudzana ndi mankhwala kapena funsani katswiri.
