C-peptide (C-peptide) da insulin (insulin) ƙwayoyin halitta ne guda biyu da ƙwayoyin tsibiran pancreatic ke samarwa yayin haɗa insulin. Bambancin tushe: C-peptide wani abu ne da ƙwayoyin tsibiran ke samarwa. Lokacin da aka haɗa insulin, ana haɗa C-peptide a lokaci guda. Saboda haka, ana iya haɗa C-peptide ne kawai a cikin ƙwayoyin tsibiran kuma ba za a samar da shi ta hanyar ƙwayoyin da ke wajen tsibiran ba. Insulin shine babban hormone da ƙwayoyin tsibiran pancreatic ke samarwa kuma ana sake shi cikin jini, wanda ke sarrafa matakan sukari na jini kuma yana haɓaka sha da amfani da glucose. Bambancin aiki: Babban aikin C-peptide shine don kiyaye daidaito tsakanin insulin da masu karɓar insulin, da kuma shiga cikin haɗa da fitar da insulin. Matsayin C-peptide na iya nuna yanayin aikin ƙwayoyin tsibiran a kaikaice kuma ana amfani da shi azaman ma'auni don kimanta aikin tsibiran. Insulin shine babban hormone na metabolism, wanda ke haɓaka ɗaukar glucose da amfani da shi ta ƙwayoyin halitta, rage yawan sukari a jini, kuma yana daidaita tsarin metabolism na mai da furotin. Bambancin yawan jini: Matakan jini na C-peptide sun fi daidaito fiye da matakan insulin saboda ana share shi a hankali. Yawan insulin a cikin jini yana shafar abubuwa da yawa, ciki har da cin abinci a cikin hanyar narkewar abinci, aikin ƙwayoyin islet, juriyar insulin, da sauransu. A taƙaice, C-peptide wani sinadari ne na insulin da ake amfani da shi musamman don tantance aikin ƙwayoyin islet, yayin da insulin shine babban hormone na metabolism da ake amfani da shi don daidaita jini.
