Kugwiritsa ntchito
White crystalline ufa
Mapulateleti oyera, crystalline kapena ufa wokhala ndi fungo lodziwika bwino.1 g imasungunuka mu 30 ml ya madzi.Amasungunuka mu ma asidi osungunuka komanso muzitsulo za alkali hydroxides.Amasungunuka pang'ono mu mowa, ndipo pafupifupi osasungunuka mu ether.Ndi optically osagwira ntchito.PH ya 1 mu 100 yankho ili pakati pa 5.6 ndi 6.1.Izi zitha kukonzedwa powonjezera methanethiol ku acrolein;ndi kutembenuka kwa mankhwala a methylthiopropionic aldehyde.
d, l-Methionine ali ndi fungo lodziwika bwino.Ndilofunikira kwa amino acid ndipo amagwiritsidwanso ntchito ngati chopatsa thanzi komanso chopatsa thanzi.
Kupanga zinthu zosasunthika zokhudzana ndi kukoma kwa zakudya kuchokera ku Strecker degradation ya DL-methionine.Kuphatikizika kwa methionine pazakudya izi kungayembekezeredwe kukulitsa kuchuluka kwa mapuloteni.Pazachuma, DL-methionine ingakhale yabwino.An nonpolar amino acid ndi oxidative stress defense properties.DL-Methionine nthawi zina amaperekedwa monga chowonjezera kwa agalu;zimathandiza kuti agalu asawononge udzu mwa kuchepetsa pH ya mkodzo.Methionine amaloledwa ngati chowonjezera ku chakudya cha nkhuku cha organic pansi pa pulogalamu ya US certified organic.
