Yintoni i-DL-Methionine CAS 59-51-8?

I-DL Methionine yicrystalline flaky emhlophe okanye icrystalline powder. Kukho ivumba elikhethekileyo. Incasa iswiti kancinci. Indawo yokunyibilika i-281 degrees (ukubola). Ixabiso le-pH ye-10% yesisombululo samanzi ngu-5.6-6.1. Ayinamsebenzi we-optical, izinzile ekushiseni nasemoyeni, kwaye ayizinzile kwi-acids eqinile, enokukhokelela kwi-demethylation. Inyibilika emanzini (3.3g/100ml, 25 degrees), dilute acid, kunye nesisombululo se-dilute. Inganyibiliki kakhulu kwi-ethanol kwaye phantse ayinyibiliki kwi-ether.

Isicelo

I-DL Methionine ifanelekile kuthintelo kunye nokunyangwa kwezifo zesibindi kunye ne-arsenic okanye i-benzene poisoning. Ingasetyenziselwa ukunyanga ukungondleki okubangelwa kukunqongophala kweprotheyini ngenxa yesifo segazi kunye nezifo ezosulelayo ezingapheliyo. I-DL Methionine ingasetyenziswa njenge-reagent ye-biochemical kuphando lwe-biochemical; Ukusetyenziswa kokulima kwezilwanyana ezanyisayo kunye neeseli zezinambuzane ezibhalwe ngee-isomers ezixubeneyo
