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

I-DL Methionine iyikristale emhlophe egqagqene noma i-crystalline powder. Kukhona iphunga elikhethekile. Ukunambitheka kumnandi kancane. Iphuzu lokuncibilika 281 degrees (ukubola). Inani le-pH lesisombululo esinamanzi esingu-10% ngu-5.6-6.1. Ayinawo umsebenzi we-optical, izinzile ekushiseni nasemoyeni, futhi ayizinzile kuma-acids aqinile, angaholela ekuphelelweni kwe-methylation. Iyancibilika emanzini (3.3g/100ml, 25 degrees), i-dilute acid, kanye nesisombululo se-dilute. Ayincibiliki ngokwedlulele ku-ethanol futhi cishe ayincibiliki ku-ether.

Isicelo

I-DL Methionine ilungele ukuvimbela nokwelashwa kwezifo zesibindi kanye nobuthi be-arsenic noma be-benzene. Ingase futhi isetshenziselwe ukwelapha ukungondleki okubangelwa ukuntuleka kwamaprotheni ngenxa yesifo sohudo kanye nezifo ezithathelwanayo ezingapheli. I-DL Methionine ingasetshenziswa njenge-reagent ye-biochemical ocwaningweni lwe-biochemical; Ukutshala ukusetshenziswa kwamaseli ezilwane ezincelisayo nezinambuzane abhalwe ngama-isomer axubile
