Taw qhia

Boc-L-threonine yog ib qho organic compound. Nws yog cov khoom dawb uas yog soluble hauv qee cov kuab tshuaj organic xws li dimethylthionamide (DMSO), ethanol thiab chloroform.

Nws tuaj yeem npaj ua Boc-L-threonine los ntawm cov tshuaj tiv thaiv ntawm cov amino acid tiv thaiv pawg.

 

Ib txoj hauv kev los npaj Boc-L-threonine yog thawj zaug ua rau threonine nrog Boc acid los ntawm cov tshuaj tiv thaiv acid-catalyzed los tsim cov Boc threonine ester, thiab tom qab ntawd kom tau txais Boc-L-threonine los ntawm alkaline hydrolysis cov tshuaj tiv thaiv.

Nws yog ib qho tshuaj thiab yuav tsum tau ua haujlwm nyob rau hauv ib cheeb tsam uas muaj cua zoo nrog cov khoom tiv thaiv tus kheej tsim nyog xws li hnab looj tes thiab tsom iav. Tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag, thiab tsis txhob nqus cov plua plav lossis roj. Thaum ntsib daim tawv nqaij lossis qhov muag, yaug tam sim ntawd nrog dej ntau thiab nrhiav kev kho mob.
