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

DL Methionine ndi ufa woyera wosalala kapena wosalala. Uli ndi fungo lapadera. Kukoma kwake ndi kokoma pang'ono. Kusungunuka madigiri 281 (kuwola). pH ya yankho lamadzi la 10% ndi 5.6-6.1. Lilibe mphamvu yowunikira, ndi lokhazikika kutentha ndi mpweya, ndipo silikhazikika ku asidi amphamvu, zomwe zingayambitse demethylation. Limasungunuka m'madzi (3.3g/100ml, madigiri 25), asidi wosungunuka, ndi yankho losungunuka. Silisungunuka kwambiri mu ethanol ndipo silisungunuka kwambiri mu ether.

Kugwiritsa ntchito

DL Methionine ndi yoyenera kupewa ndi kuchiza matenda a chiwindi ndi poizoni wa arsenic kapena benzene. Ingagwiritsidwenso ntchito pochiza kusowa kwa zakudya m'thupi komwe kumachitika chifukwa cha kusowa kwa mapuloteni chifukwa cha kamwazi ndi matenda opatsirana osatha. DL Methionine ingagwiritsidwe ntchito ngati chothandizira cha biochemical pa kafukufuku wa biochemical; Kugwiritsa ntchito kulima maselo a nyama zoyamwitsa ndi tizilombo omwe ali ndi ma isomers osakanikirana
