C-peptide (C-P-Peptin) ndi insulin (insulin) ndi mamolekyulu awiri omwe amapangidwa ndi ma celetic ma cell synthesis. Gweroni: C-peptide ndi gawo la insulin synthesis ndi maselo a Islet. Insulin ikakhazikika, C-peptide imapangidwa nthawi yomweyo. Chifukwa chake, C-peptirira imatha kuphatikizidwa mu ma cell a islet ndipo sadzapangidwa ndi maselo kunja. Insulin ndiye mahomoni akuluakulu a mahomoni ndi ma celetic ma cells ndikumasulidwa m'magazi, omwe amawongolera milingo yamagazi ndikulimbikitsa mayamwidwe ndi kugwiritsa ntchito shuga. Kusintha kwa ntchito: Ntchito yayikulu ya C-peptide ndikuti mukhalebe osamala pakati pa insulin ndi insulin recectors, komanso kutenga nawo gawo pa synthesin ndi secreun. Mulingo wa C-Peptide akhoza kuwonetsa mosapita m'mbali ma cell a islet ndipo amagwiritsidwa ntchito ngati cholozera kuti athetse ntchito ya ma islet. Insulin ndiye ma hormone wamkulu wa metabolic, yomwe imalimbikitsa kukweza ndi kugwiritsa ntchito shuga, amachepetsa shuga, ndikuwongolera kagayidwe ka mafuta ndi mapuloteni. Kusiyana kwa Magazi: C-milingo yamagazi imakhala yokhazikika kuposa milingo ya insulini chifukwa imayeretsedwa pang'onopang'ono. Kukhazikika kwa magazi kwa insulin kumakhudzidwa ndi zinthu zambiri, kuphatikizapo kudya kwa chakudya m'mphepete mwa insulinte, pomwe inlider ndi ma homini wamkulu pa metabolic komwe amagwiritsidwa ntchito kuwongolera magazi
