C-peptide (C-peptide) ndi insulin (insulin) ndi mamolekyu awiri opangidwa ndi ma pancreatic islet cell panthawi ya insulin synthesis. Kusiyana kochokera: C-peptide ndi chopangidwa kuchokera ku insulin synthesis ndi ma islet cell. Insulin ikapangidwa, C-peptide imapangidwa nthawi yomweyo. Chifukwa chake, C-peptide imatha kupangidwa m'maselo a islet ndipo sidzapangidwa ndi ma cell kunja kwa zisumbu. Insulin ndiye timadzi tambiri tomwe timapangidwa ndi ma cell a pancreatic islet ndikutulutsidwa m'magazi, omwe amawongolera kuchuluka kwa shuga m'magazi ndikulimbikitsa kuyamwa ndikugwiritsa ntchito shuga. Kusiyana kwa ntchito: Ntchito yayikulu ya C-peptide ndikusunga bwino pakati pa insulin ndi zolandilira insulin, komanso kutenga nawo mbali pakupanga ndi kutulutsa kwa insulin. Mulingo wa C-peptide ukhoza kuwonetsa mosadukiza momwe ma cell a islet amagwirira ntchito ndipo amagwiritsidwa ntchito ngati index yowunika momwe zisumbu zimagwirira ntchito. Insulin ndiye timadzi tambiri tambiri timene timathandizira kuyamwa ndikugwiritsa ntchito shuga m'maselo, kumachepetsa kuchuluka kwa shuga m'magazi, ndikuwongolera kagayidwe kazakudya zamafuta ndi mapuloteni. Kusiyana kwa ndende ya magazi: C-peptide m'magazi imakhala yokhazikika kuposa insulini chifukwa imachotsedwa pang'onopang'ono. Kuchuluka kwa insulini m'magazi kumakhudzidwa ndi zinthu zambiri, kuphatikiza kudya m'matumbo am'mimba, kugwira ntchito kwa ma islet cell, insulin kukana, etc. insulin ndiye timadzi tambiri tambiri tomwe timagwiritsidwa ntchito powongolera magazi
