Taw qhia

N-Acetyl-L-tyrosine yog ib qho natural amino acid derivative uas yog tsim los ntawm cov tshuaj tiv thaiv ntawm tyrosine thiab acetylating agents. N-acetyl-L-tyrosine yog cov hmoov dawb crystalline uas tsis qab thiab tsw tsw. Nws muaj solubility zoo thiab soluble hauv dej thiab ethanol.

 

Kev npaj ntawm N-acetyl-L-tyrosine tuaj yeem tau txais los ntawm kev ua haujlwm tyrosine nrog tus neeg sawv cev acetylating (xws li, acetyl chloride) nyob rau hauv cov xwm txheej alkaline. Thaum cov tshuaj tiv thaiv tiav, cov khoom tuaj yeem ua kom huv los ntawm cov kauj ruam xws li crystallization thiab ntxuav.

 

Hais txog kev nyab xeeb, N-acetyl-L-tyrosine yog suav tias yog ib qho kev nyab xeeb zoo thiab feem ntau tsis ua rau muaj kev phiv loj heev. Kev siv ntau dhau lossis siv mus ntev yuav ua rau qee qhov tsis xis nyob xws li mob taub hau, mob plab, thiab lwm yam.
