Boc-D-Tyrosine (CAS # 70642-86-3) Kev taw qhia

Boc-D-Tyrosine yog cov tshuaj lom neeg, nws cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb yog raws li hauv qab no:

Khoom: Nws yog dawb crystalline khoom uas ruaj khov ntawm chav tsev kub. Boc-D-tyrosine yog ib qho chaw tiv thaiv amine pawg, qhov twg Boc sawv cev rau tert-butoxycarbonyl, uas tiv thaiv cov reactivity ntawm cov amino pawg.

Siv:
Boc-D-tyrosine feem ntau yog siv hauv thaj chaw ntawm cov organic synthesis thiab feem ntau yog siv los ua cov khoom pib rau peptide synthesis. Nws tuaj yeem cuam tshuam nrog lwm cov amino acids lossis peptides los tsim cov peptide ntawm kev txaus siab los ntawm cov tshuaj tiv thaiv uas tiv thaiv pawg amine.

Txoj kev:
Boc-D-tyrosine tuaj yeem ua ke los ntawm ntau cov tshuaj tiv thaiv. Ib txoj hauv kev sib xyaw ua ke yog tsim cov tshuaj tiv thaiv Boc los ntawm kev ua haujlwm D-tyrosine nrog cov tshuaj ester lossis anhydride.

Cov ntaub ntawv kev nyab xeeb:
Boc-D-Tyrosine kuj ruaj khov nyob rau hauv chav tsev kub, tab sis yuav tsum raug zam kom raug rau lub teeb ci. Nws yog soluble hauv cov organic solvents xws li ethanol thiab dimethylformamide. Tsim nyog kev kuaj xyuas kev nyab xeeb, suav nrog kev hnav cov hnab looj tes tshuaj, tsom iav, thiab lub tsho (lab), yuav tsum tau ua raws li thaum siv lossis tuav Boc-D-Tyrosine los tiv thaiv kev sib cuag ntawm daim tawv nqaij thiab qhov muag.
