I-C-peptide (i-C-peptide) kanye ne-insulin (i-insulin) zingama-molecule amabili akhiqizwa amaseli e-pancreatic islet ngesikhathi sokwenziwa kwe-insulin. Umehluko womthombo: I-C-peptide ingumkhiqizo ophumayo wokwenziwa kwe-insulin ngamaseli e-islet. Lapho i-insulin ikhiqizwa, i-C-peptide yenziwa ngesikhathi esifanayo. Ngakho-ke, i-C-peptide ingakhiwa kuphela kumaseli e-islet futhi ngeke ikhiqizwe amaseli angaphandle kweziqhingi. I-insulin iyi-hormone eyinhloko eyenziwe ngamaseli e-pancreatic islet futhi ikhishwe egazini, elawula amazinga kashukela egazini futhi ikhuthaze ukumuncwa nokusetshenziswa kwe-glucose. Umehluko womsebenzi: Umsebenzi oyinhloko we-C-peptide ukugcina ibhalansi phakathi kwe-insulin nama-insulin receptors, nokubamba iqhaza ekwakhiweni nasekukhiqizweni kwe-insulin. Izinga le-C-peptide lingabonisa ngokungaqondile isimo sokusebenza kwamaseli e-islet futhi lisetshenziswa njengenkomba yokuhlola umsebenzi weziqhingi. I-insulin iyi-hormone eyinhloko ye-metabolic, ekhuthaza ukumuncwa nokusetshenziswa kwe-glucose ngamaseli, yehlisa ukumuncwa kweshukela egazini, futhi ilawula inqubo ye-metabolic yamafutha namaprotheni. Umehluko wokumuncwa kwegazi: Amazinga egazi e-C-peptide azinzile kakhulu kunamazinga e-insulin ngoba asuswa kancane. Ukuhlushwa kwe-insulin egazini kuthinteka yizici eziningi, okuhlanganisa ukudla okudliwayo emgudwini wokugaya ukudla, ukusebenza kweseli le-islet, ukumelana ne-insulin, njll. Ngamafuphi, i-C-peptide iwumkhiqizo we-insulin osetshenziswa ngokuyinhloko ukuhlola ukusebenza kweseli le-islet, kanti i-insulin iyi-hormone eyinhloko ye-metabolic esetshenziswa ukulawula igazi.
