Taw qhia
Boc-Gly-Gly-OH, lub npe hu ua Boc-Gly-Gly-OH (N-tert-butyloxycarbonyl-glycyl-glycine, Boc-Gly-Gly-OH luv luv), yog cov tshuaj lom neeg. Cov hauv qab no yog cov lus piav qhia ntawm nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
1. Xwm:
Boc-Gly-Gly-OH yog cov khoom dawb mus rau dawb nrog lub siab melting point thiab solubility tsawg. Nws yog ruaj khov ntawm chav tsev kub, tab sis tej zaum yuav degrade nyob rau hauv siab kub, ncaj qha tshav ntuj los yog ib puag ncig ntub.
2. Siv:
Boc-Gly-Gly-OH yog ib qho tshuaj tiv thaiv kab mob amino acid uas nquag siv. Nws yog siv los tiv thaiv cov amino pawg ntawm glycylglycine nyob rau hauv chemical synthesis kom tsis txhob muaj cov tshuaj tiv thaiv sab hauv tshuaj. Thaum lub sij hawm synthesis ntawm ib tug polypeptide los yog protein, ib tug Boc-Gly-Gly-OH yuav muab ntxiv raws li ib tug tiv thaiv pab pawg neeg thiab ces muab tshem tawm nyob rau hauv tsim nyog tej yam kev mob kom tso cai rau lub polypeptide saw txuas ntxiv.
3. Txoj kev npaj:
Kev npaj ntawm Boc-Gly-Gly-OH feem ntau yog ua los ntawm cov txheej txheem organic synthesis. Ib txoj hauv kev ntawm kev npaj yog ua rau ob pawg hydroxyl ntawm glycine cais nrog Boc-anhydride (tert-butyloxycarbonyl anhydride) los ua Boc-Gly-Gly-OH. Cov tshuaj tiv thaiv yuav tsum tau tswj xyuas thaum lub sij hawm npaj los xyuas kom meej tawm los thiab purity.
4. Cov ntaub ntawv kev nyab xeeb:
Boc-Gly-Gly-OH kuj tseem muaj kev nyab xeeb nyob rau hauv kev sim dav dav, tab sis cov teeb meem hauv qab no tseem yuav tsum tau saib xyuas:
-Cov tshuaj no tuaj yeem ua rau tawv nqaij, qhov muag thiab ua pa, yog li siv cov kev tiv thaiv tsim nyog xws li kuaj cov hnab looj tes thiab tsom iav thaum raug.
-Tsis txhob sib cuag nrog cov oxidants los yog cov nplaim taws thaum siv los yog cia kom tsis txhob muaj xwm txheej txaus ntshai xws li hluav taws kub lossis tawg.
-Txoj kev tuav thiab pov tseg cov khoom seem thiab pov tseg hauv chav kuaj kom raug, ua raws li kev coj ua thiab kev tswj hwm kev nyab xeeb tam sim no.
