    ʻO ka pauka kristal keʻokeʻo
    ʻO nā platelets keʻokeʻo, crystalline a i ʻole ka pauka me kahi ʻala ʻano.Hoʻokahi g e hoʻoheheʻe ʻia ma kahi o 30 mL o ka wai.Hiki ke hoʻoheheʻe ʻia i loko o nā waikawa dilute a me nā hoʻonā o alkali hydroxides.Hiki ke hoʻoheheʻe ʻia i loko o ka waiʻona, a ʻaʻole hiki ke hoʻoheheʻe ʻia i ka ether.ʻAʻole hana ʻino.Aia ma waena o 5.6 a me 6.1 ka pH o kahi hoʻonā 1 i 100.Hiki ke hoʻomākaukau ʻia kēia mea ma ka hoʻohui ʻana i ka methanethiol i ka acrolein;ma ka hoʻololi kemika o ka methylthiopropionic aldehyde.

    d,l-Methionine kekahi pilau ano.He waikawa amino koʻikoʻi ia a hoʻohana ʻia ma ke ʻano he meaʻai a me ka meaʻai.

    Iecaianoaaiiuo o ka volatile pūhui e pili ana i ka ono o ka ai mai ka Strecker degradation o DL-methionine.ʻO ka hoʻohui ʻana i ka methionine i ka nui kūpono i kēia mau meaʻai e manaʻo ʻia e hoʻomaikaʻi i ka waiwai protein.Ma ka hoʻokele waiwai, ʻoi aku ka maikaʻi o DL-methionine.ʻO ka waikona amino nonpolar pono me nā waiwai pale koʻikoʻi oxidative. Hāʻawi ʻia ʻo DL-Methionine i kekahi manawa i mea hoʻohui i nā ʻīlio;kōkua ia i ka mālama ʻana i nā ʻīlio mai ka ʻino ʻana i ka mauʻu ma o ka hōʻemi ʻana i ka pH o ka mimi. Ua ʻae ʻia ka Methionine ma ke ʻano he mea hoʻohui i nā meaʻai moa ma lalo o ka papahana organik i hōʻoia ʻia e US.
