Isingeniso

I-N-acetyl-L-methionine iyinhlanganisela yezinto eziphilayo. Iphuma ku-L-methionine futhi inamaqembu asebenzayo e-acetylated.

 

I-N-acetyl-L-methionine ivame ukutholwa nge-esterification ye-L-methionine nge-acetic anhydride. Izimo ezithile zokusabela zingashintshwa ngokuvumelana nezidingo zangempela kanye nezimo zokusabela.

 

Ulwazi lokuphepha: I-N-acetyl-L-methionine iyikhemikhali futhi kufanele isetshenziselwe ukunaka ukuphepha. Ukuthintana nesikhumba namehlo kufanele kugwenywe, futhi uma kukhona ukuthintana, hlambulula ngokushesha ngamanzi. Kufanele igcinwe endaweni eyomile, epholile, enomoya omuhle, kude nomlilo nezinto ezivuthayo. Lapho kusetshenziswa, izinqubo ezifanele zokusebenza zokuphepha kufanele zilandelwe futhi kugqokwe okokuvikela okufanele. Lapho kulahlwa imfucuza, kufanele ilahlwe ngokuhambisana nemithetho yendawo.
