Malic Acid
Malic acid, tseem hu ua 2-hydroxysuccinic acid, muaj ob lub stereoisomers vim los ntawm asymmetric carbon atom hauv cov qauv molecule. Hauv xwm, nws tshwm sim nyob rau hauv peb hom, hu ua D-malic acid, L-malic acid thiab ib qho sib xyaw ua ke DL-malic acid. Dawb siv lead ua hmoov los yog crystalline hmoov, uas muaj muaj zog hygroscopicity thiab yog yooj yim soluble hauv dej thiab ethanol. Muaj qhov tshwj xeeb qab ntxiag qaub saj. Malic acid feem ntau yog siv hauv kev lag luam khoom noj thiab tshuaj lag luam.
