I-C-peptide (i-C-peptide) kunye ne-insulin (i-insulin) ziimolekyuli ezimbini eziveliswa ziiseli ze-pancreatic islet ngexesha lokwenziwa kwe-insulin. Umahluko womthombo: I-C-peptide yimveliso ephuma kwi-insulin synthesis ziiseli ze-islet. Xa i-insulin isenziwa, i-C-peptide yenziwa ngaxeshanye. Ke ngoko, i-C-peptide inokwenziwa kuphela kwiiseli ze-islet kwaye ayizukuveliswa ziiseli ezingaphandle kwe-islet. I-insulin yi-hormone ephambili eyenziwe ziiseli ze-pancreatic islet kwaye ikhutshwe egazini, elawula amanqanaba eswekile egazini kwaye ikhuthaza ukufunxwa nokusetyenziswa kwe-glucose. Umahluko womsebenzi: Umsebenzi ophambili we-C-peptide kukugcina ibhalansi phakathi kwe-insulin kunye nee-receptors ze-insulin, kunye nokuthatha inxaxheba ekuhlanganisweni nasekukhutshweni kwe-insulin. Inqanaba le-C-peptide linokubonakalisa ngokungathanga ngqo imeko yokusebenza kweeseli ze-islet kwaye lisetyenziswa njengesalathiso sokuvavanya umsebenzi wee-islet. I-insulin yi-hormone ephambili ye-metabolic, ekhuthaza ukufunxwa nokusetyenziswa kwe-glucose ziiseli, yehlisa uxinzelelo lweswekile egazini, kwaye ilawula inkqubo ye-metabolic yamafutha kunye neeproteni. Umahluko woxinzelelo lwegazi: Amanqanaba egazi le-C-peptide azinzile ngakumbi kunamanqanaba e-insulin kuba asuswa kancinci. Ubungakanani be-insulin egazini buchaphazeleka zizinto ezininzi, kuquka ukutya okutyiwayo kwindlela yokugaya ukutya, ukusebenza kweeseli ze-islet, ukuxhathisa i-insulin, njl. Ngamafutshane, i-C-peptide yimveliso ye-insulin esetyenziswa kakhulu ukuvavanya ukusebenza kweeseli ze-islet, ngelixa i-insulin yeyona hormone iphambili ye-metabolic esetyenziselwa ukulawula igazi.
