Codsiga:

DCC (N,N'-Dicyclohexylcarbodiimide, CAS: 538-75-0) waxa loo isticmaalaa kimistariga peptide sida reagement isku xidha.Inta badan loo isticmaalo isku-dhafka macmalka ah ee peptides-ka Uumi acids amino.Tusaale ahaan, isku-dhafka wajiga Fmoc-adag, kooxda karboxyl ee amino acid waxay samaysaa dammaanad amide ah oo ay la socdaan kooxda amino acid amino kale.Si kooxda carboxyl looga dhigo mid u dhego nugul weerarka nucleophiles, atamka oksijiinta ee sida xun loo dallaco wuxuu u baahan yahay in loo hawlgeliyo koox ka bixitaan wanaagsan, DCC ayaana ciyaartan doorkan.Atomka oksijiinta ee kooxda karboksyl-ka ee amino acid waxa uu u shaqeeyaa sida nucleophile si uu u weeraro atamka kaarboon ee ku dhex jira molecule DCC si ay DCC ugu darto kooxda karboksyl si ay u sameeyaan qaab dhismeed ester ah, taasoo ka dhigaysa weerarka nucleophilic ee kooxda amino. fududahay in la sameeyo isku-xidhka reagent.

DCC waxaa loo isticmaalaa isku-dhafka iyo fuuq-baxa amikacin iyo amino acids.waa wakiilka fuuq-baxa biochemical ee heerkulka hooseeya oo sidoo kale loo isticmaalo isku-darka acids, anhydrides, aldehydes, ketones, iwm. Japan, wakiilada fuuq-baxa ee loo isticmaalo glutathione waxay ku xisaabtamaan 90% wadarta isticmaalka.Marka badeecada loo isticmaalo sida fuuq-baxa iyo wasakheeyaha, waxaa lagu falcelin karaa waqti gaaban heerkulka qolka, iyo badeecada ka dib falcelinta waa dicyclohexylurea.Maadaama milanka badeecada ku jirta dareeraha organic uu aad u yar yahay, badeecada falcelinta way fududahay in la kala saaro;Isla mar ahaantaana, sababtoo ah alaabtu way adagtahay in lagu milmo biyaha, falcelinta ayaa wali sii socon karta xitaa xal aqueous ah.Badeecada waxaa sidoo kale loo isticmaalaa isku-dhafka peptides iyo asiidhyada nucleic.Isticmaalka alaabtan waxay si fudud u soo saari kartaa peptides ka xeryahooda kooxaha karboxyl lacag la'aan ah iyo xeryahooda leh kooxaha amino lacag la'aan ah heerkulka qolka, iyo dhalidda waa mid aad u sarreeya.Waxaa loo isticmaalaa soo saarista hypertensives iyo adenosine monophosphate wareeg ah.loo isticmaalo sidii reagent biochemical iyo synthesis organic wakiilka fuuqbaxa.
