C-peptide (C-peptide) na insulin (insulin) bụ ụmụ irighiri ihe abụọ na-emepụta site na mkpụrụ ndụ islet pancreatic n'oge njikọ insulin. Isi mmalite: C-peptide bụ ihe sitere na mmepụta insulin site na mkpụrụ ndụ islet. Mgbe a na-emepụta insulin, a na-emepụta C-peptide n'otu oge. Ya mere, C-peptide nwere ike ịmepụta naanị n'ime sel ndị dị n'àgwàetiti ma ọ gaghị emepụta ya site na mkpụrụ ndụ ndị na-abụghị agwaetiti. Insulin bụ isi homonụ nke mkpụrụ ndụ islet pancreatic mebere ma wepụta ya n'ime ọbara, nke na-achịkwa ọkwa shuga dị n'ọbara ma na-akwalite nnabata na ojiji nke glucose. Ọdịiche ọrụ: Isi ọrụ C-peptide bụ idobe nguzozi n'etiti insulin na ndị na-anabata insulin, yana isonye na njikọ na nzuzo nke insulin. Ọkwa C-peptide nwere ike gosipụta n'ụzọ na-apụtaghị ìhè ọnọdụ arụ ọrụ nke mkpụrụ ndụ islet ma jiri ya mee ihe dị ka ndeksi iji nyochaa ọrụ nke agwaetiti. Insulin bụ isi homonụ nke metabolic, nke na-akwalite nnabata na ojiji nke glucose site na mkpụrụ ndụ, na-ebelata mkpokọta shuga n'ọbara, na-achịkwa usoro metabolic nke abụba na protein. Ọdịiche ịta ahụhụ ọbara: Ọkwa C-peptide kwụsiri ike karịa ọkwa insulin n'ihi na a na-ehichapụ ya nke nta nke nta. A na-emetụta mkpokọta insulin n'ọbara n'ọtụtụ ihe, gụnyere iri nri na tract gastrointestinal, ọrụ sel islet, nguzogide insulin, wdg. Insulin bụ homonụ metabolic bụ isi a na-eji ahazi ọbara
