Ntchito:

DCC (N,N'-Dicyclohexylcarbodiimide, CAS: 538-75-0) imagwiritsidwa ntchito mu chemistry ya peptide ngati cholumikizira cholumikizira.Makamaka ntchito yokumba synthesis wa peptides Condensation wa amino zidulo.Mwachitsanzo, mu Fmoc-solid phase synthesis, gulu la carboxyl la amino acid limapanga mgwirizano wa amide ndi gulu la amino la amino acid ina.Kuti gulu la carboxyl likhale lomvera kuukira kwa ma nucleophiles, atomu ya okosijeni yomwe ili ndi mpweya woipa imayenera kulowetsedwa kukhala gulu lochoka bwino, ndipo DCC imagwira ntchitoyi.Atomu ya okosijeni ya gulu la carboxyl pa amino acid imakhala ngati nucleophile kuukira atomu ya kaboni pakati pa molekyulu ya DCC kuti DCC imalumikizana ndi gulu la carboxyl kupanga mawonekedwe a ester, kupanga nucleophilic attack ya gulu la amino. zosavuta kuchita coupling reagent.

DCC imagwiritsidwa ntchito popanga komanso kutaya madzi m'thupi kwa amikacin ndi amino acid.ndi yabwino yotsika kutentha kwa biochemical dehydrating agent ndipo imagwiritsidwanso ntchito popanga ma acid, anhydrides, aldehydes, ketoni, ndi zina zotero. Ku Japan, mankhwala osokoneza bongo omwe amagwiritsidwa ntchito pa glutathione chifukwa cha 90% ya ntchito yonse.Mankhwalawa akagwiritsidwa ntchito ngati dehydration ndi condensing agent, amatha kuchitapo kanthu pakanthawi kochepa kutentha kwa firiji, ndipo mankhwalawa atatha kuchitapo kanthu ndi dicyclohexylurea.Popeza solubility wa mankhwala mu zosungunulira organic ndi laling'ono kwambiri, zimene mankhwala n'zosavuta kupatukana;nthawi yomweyo, chifukwa mankhwalawa ndi ovuta kusungunuka m'madzi, zomwe zimachitika zimatha kupitilira ngakhale munjira yamadzi.Mankhwalawa amagwiritsidwanso ntchito popanga peptides ndi nucleic acid.Kugwiritsa ntchito mankhwalawa kumatha kuphatikizira ma peptides kuchokera kumagulu okhala ndi magulu aulere a carboxyl ndikuphatikizana ndi magulu a amino aulere pa kutentha kwa firiji, ndipo zokolola zake ndizambiri.Ntchito kupanga hypertensives ndi cyclic adenosine monophosphate.amagwiritsidwa ntchito ngati biochemical reagent ndi organic synthesis dehydration condensing agent.
