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

I-DL Methionine iyi-crystalline emhlophe ecwebezelayo noma impuphu yekristalu. Kunephunga elikhethekile. Ukunambitheka kumnandi kancane. Iphuzu lokuncibilika lingu-281 degrees (ukubola). Inani le-pH lesisombululo samanzi esingu-10% lingu-5.6-6.1. Ayinawo umsebenzi wokukhanya, izinzile ekushiseni nasemoyeni, futhi ayizinzile kuma-asidi aqinile, okungaholela ekususweni kwe-methylation. Iyancibilika emanzini (3.3g/100ml, ama-degree angu-25), i-acid encibilikisiwe, kanye nesisombululo esincibilikisiwe. Ayincibiliki kakhulu ku-ethanol futhi cishe ayincibiliki ku-ether.

Isicelo

I-DL Methionine ifanele ukuvimbela nokwelapha izifo zesibindi kanye nobuthi be-arsenic noma i-benzene. Ingasetshenziswa futhi ekwelapheni ukungondleki okubangelwa ukuntuleka kwamaprotheni ngenxa yesifo sohudo kanye nezifo ezithathelwanayo ezingamahlalakhona. I-DL Methionine ingasetshenziswa njenge-reagent yamakhemikhali ocwaningweni lwe-biochemical; Ukusetshenziswa kokutshala kwamaseli ezilwane ezincelisayo nezinambuzane abhalwe ngama-isomers axubile
