Isingeniso

I-N-Acetyl-L-tyrosine i-amino acid derivative yemvelo eyakhiwe ukusabela kwe-tyrosine nama-acetylating agents. I-N-acetyl-L-tyrosine iyimpushana emhlophe ecwebezelayo engenakunambitheka futhi engenaphunga. Inoncibilika kahle futhi iyancibilika emanzini ne-ethanol.

 

Ukulungiswa kwe-N-acetyl-L-tyrosine kungatholakala ngokuphendula i-tyrosine nge-acetylating agent (isb, i-acetyl chloride) ngaphansi kwezimo ze-alkali. Uma ukusabela sekuqediwe, umkhiqizo ungahlanzwa ngezinyathelo ezifana ne-crystallization nokugeza.

 

Mayelana nokuphepha, i-N-acetyl-L-tyrosine ibhekwa njengenhlanganisela ephephile futhi ngokuvamile ayibangeli imiphumela emibi kakhulu. Ukusetshenziswa ngokweqile noma ukusebenzisa isikhathi eside kungase kubangele ukungakhululeki okuthile okufana nekhanda elibuhlungu, ukucasuka kwesisu, njll.
