Taw qhia

N-Boc-O-benzyl-L-tyrosine yog cov organic compound uas muaj N-Boc tiv thaiv pawg, benzyl pawg thiab L-tyrosine pawg hauv nws cov qauv tshuaj.

 

Cov nram qab no yog hais txog cov khoom ntawm N-Boc-O-benzyl-L-tyrosine:

Lub cev muaj zog: hmoov khoom, tsis muaj xim lossis dawb.

Chemical Properties: N-Boc tiv thaiv pab pawg yog cov pab pawg tiv thaiv rau cov amino pawg, uas tuaj yeem tiv thaiv tyrosine hauv kev sib txuas thiab cov tshuaj tiv thaiv yam tsis raug rhuav tshem. Benzyl pawg yog cov tshuaj tsw qab uas muaj cov tshuaj muaj zog. L-Tyrosine yog ib qho amino acid uas muaj zog xws li acidity, alkalinity, solubility, thiab lwm yam.

 

Kev siv tseem ceeb ntawm N-Boc-O-benzyl-L-tyrosine suav nrog, tab sis tsis txwv rau:

 

Cov txheej txheem ntawm kev npaj N-Boc-O-benzyl-L-tyrosine feem ntau yog los ntawm cov tshuaj synthesis. Ib txoj hauv kev zoo tshaj plaws yog siv L-tyrosine ua cov khoom pib thiab dhau los ntawm cov txheej txheem tshuaj tiv thaiv, suav nrog kev tiv thaiv esterification thiab N-Boc, thaum kawg tau txais cov khoom lag luam.

 

Thaum siv N-Boc-O-benzyl-L-tyrosine, cov ntaub ntawv kev nyab xeeb hauv qab no yuav tsum raug sau tseg:

Tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag kom tsis txhob khaus lossis puas.

Tsis txhob nqus cov plua plav lossis cov tshuaj vapors thiab ua haujlwm hauv qhov chaw uas muaj cua zoo.

Ua raws li kev tiv thaiv tus kheej kom raug, xws li hnav hnab looj tes, tsom iav, thiab khaub ncaws tiv thaiv.

Thaum khaws cia, kev sib cuag nrog cov oxidants lossis cov kua qaub muaj zog yuav tsum zam kom tsis txhob muaj kev phom sij txaus ntshai.

Thaum siv lossis tuav, nws yog ib qho tseem ceeb uas yuav tsum ua raws li kev kuaj xyuas kom raug thiab ua raws li kev ntsuas kev nyab xeeb.
