Intangiriro

DL-Methionine ni aside amine idafite polar. Ibiranga ni ifu yera ya kristaline, impumuro nziza, isharira gato, gushonga mumazi.

 

DL-Methionine irashobora gutegurwa nuburyo butandukanye. Uburyo bukoreshwa cyane ni binyuze muri synthesis. By'umwihariko, DL-methionine irashobora kubyara reaction ya acylation ya alanine ikurikirwa no kugabanuka.

 

Amakuru yumutekano: DL-Methionine ifite umutekano hamwe no gukoresha bisanzwe no gufata neza. Kunywa cyane birashobora gutera ingaruka zimwe nko kugira isesemi, kuruka, no gucibwamo. Igomba gukoreshwa yitonze kumatsinda yabantu, nkabagore batwite, impinja nabana bato, nabantu bafite allergie.
