Nhanganyaya

DL-Methionine isiri-polar amino acid. Zvimiro zvaro zvichena crystalline poda, isina kunhuhwirira, inovava zvishoma, inonyungudika mumvura.

 

DL-Methionine inogona kugadzirwa nenzira dzakasiyana siyana. Iyo inonyanya kushandiswa nzira ndeye kuburikidza nemakemikari synthesis. Kunyanya, DL-methionine inogona kugadzirwa neacylation reaction yealanine inoteverwa nekuderedza kuita.

 

Ruzivo Rwekuchengetedza: DL-Methionine yakachengeteka nekushandiswa kwakajairwa uye kudya zvine mwero. Kunyanya kunwa kunogona kukonzera mimwe mhedzisiro yakadai sekusvotwa, kurutsa, uye manyoka. Inofanira kushandiswa nekuchenjerera kune mamwe mapoka evanhu, akadai sevakadzi vane pamuviri, vacheche nevana vaduku, uye vanhu vane allergies.
