DL-Methionine CAS 59-51-8
He pauka kristal keʻokeʻo a i ʻole ka pauka kristal ʻo DL Methionine. He ʻala kūikawā. He ʻono iki ka ʻono. He 281 degere ka helu heheʻe (decomposition). ʻO ka waiwai pH o kahi hopena wai 10% he 5.6-6.1. ʻAʻohe ona hana optical, paʻa i ka wela a me ka ea, a paʻa ʻole i nā waikawa ikaika, hiki ke alakaʻi i ka demethylation. Hoʻoheheʻe ʻia i ka wai (3.3g/100ml, 25 degere), waikawa dilute, a me ka hopena dilute. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka ethanol a aneane hiki ʻole ke hoʻoheheʻe ʻia i ka ether.

He kūpono ʻo DL Methionine no ka pale ʻana a me ka mālama ʻana i nā maʻi akepaʻa a me ka lāʻau make arsenic a benzene paha. Hiki ke hoʻohana ʻia e mālama i ka maʻi ʻai i hoʻokumu ʻia e ka nele o ka protein ma muli o ka maʻi dysentery a me nā maʻi lele mau. Hiki ke hoʻohana ʻia ʻo DL Methionine ma ke ʻano he reagent biochemical no ka noiʻi biochemical; Hoʻopili mahiʻai o nā cell mammalian a me nā pepeke i lepili ʻia me nā isomers i hui pū ʻia.
Hoʻopili pinepine ʻia i loko o 25kg / pahu, a hiki ke hana ʻia kahi pūʻolo i hoʻopilikino ʻia.
