Ka whakamahia te DCC (N,N'-Dicyclohexylcarbodiimide, CAS: 538-75-0) i roto i te matū peptide hei reagent hono.Te nuinga whakamahia mo te kōtuitanga horihori o peptides Condensation o waikawa amino.Hei tauira, i roto i te whakahiato o te wahanga Fmoc-solid, ka hangaia e te roopu carboxyl o te waikawa amino he here amide ki te roopu amino o tetahi atu waikawa amino.Kia pai ake ai te aro atu o te roopu carboxyl ki te whakaekenga o nga nucleophiles, me whakahoehia te ngota hāora kua toraro ki roto i te roopu wehe atu, a ko DCC tenei mahi.Ko te ngota hāora o te roopu carboxyl i runga i te waikawa amino ka mahi hei nucleophile ki te whakaeke i te ngota waro i waenganui o te ngota DCC kia hono te DCC me te roopu carboxyl ki te hanga i te hanganga ester, ka hanga i te whakaeke nucleophilic o te roopu amino. ngawari ki te kawe i te reagent hono.

Ka whakamahia te DCC mo te whakahiato me te maroke o te amikacin me te waikawa amino.he pai te iti-pamahana biochemical dehydrating kaihoko me te whakamahia hoki mo te kōtuitanga o waikawa, anhydride, aldehydes, ketones, me ētahi atu I roto i te Japan, dehydrating āpiha whakamahia mō te glutathione pūkete mō te 90% o te pau katoa.I te wa e whakamahia ana te hua ki te whakamaroketanga me te kaipatu, ka taea te whakahoki i roto i te wa poto i te pāmahana rūma, ko te hua i muri i te tauhohenga ko te dicyclohexylurea.I te mea he iti rawa te whakarewatanga o te hua i roto i te whakarewa pararopi, he ngawari te wehe i te hua tauhohenga;i te wa ano, na te mea he uaua ki te memeha i roto i te wai te hua, ka taea tonu te tauhohenga ahakoa i roto i te wairewa wai.Ka whakamahia hoki te hua mo te whakahiato o nga peptides me nga waikawa nucleic.Ko te whakamahinga o tenei hua ka taea te whakahiato i nga peptides mai i nga pūhui me nga roopu carboxyl kore utu me nga huinga me nga roopu amino kore utu i te pāmahana rūma, a he tino tiketike te hua.Ka whakamahia mo te hanga o te hypertensive me te adenosine monophosphate cyclic.whakamahia hei reagent matū koiora me te matū whakakoi waiora.
