Kodi DL-Methionine CAS 59-51-8 ndi chiyani?

DL Methionine ndi ufa wonyezimira wonyezimira kapena crystalline ufa. Pali fungo lapadera. Kukoma kumakoma pang'ono. Malo osungunuka madigiri 281 (kuwola). Phindu la pH la 10% yankho lamadzi ndi 5.6-6.1. Ilibe ntchito ya kuwala, imakhala yokhazikika kutentha ndi mpweya, ndipo imakhala yosasunthika ku ma asidi amphamvu, omwe angayambitse demethylation. Ndi sungunuka m'madzi (3.3g/100ml, 25 madigiri), dilute asidi, ndi kuchepetsa njira. Zosasungunuka kwambiri mu ethanol komanso pafupifupi osasungunuka mu etha.

Kugwiritsa ntchito

DL Methionine ndi oyenera kupewa ndi kuchiza matenda a chiwindi ndi arsenic kapena benzene poizoni. Itha kugwiritsidwanso ntchito pochiza kusowa kwa zakudya m'thupi chifukwa cha kuchepa kwa mapuloteni chifukwa cha kamwazi komanso matenda opatsirana osatha. DL Methionine angagwiritsidwe ntchito ngati reagent biochemical kwa kafukufuku zamoyo; Kukulitsa kugwiritsa ntchito ma cell a mammalian ndi tizilombo olembedwa ndi ma isomers osakanikirana
