C-peptide, tseem hu ua linking peptide, yog ib qho amino acid tseem ceeb hauv kev tsim insulin. Nws raug tso tawm los ntawm lub pancreas nrog rau insulin thiab ua haujlwm ua lub cim tseem ceeb rau kev ntsuas kev ua haujlwm ntawm pancreas. Txawm hais tias insulin tswj cov ntshav qab zib, C-peptide ua lub luag haujlwm sib txawv thiab tseem ceeb hauv kev nkag siab txog ntau yam mob, tshwj xeeb tshaj yog ntshav qab zib. Los ntawm kev ntsuas cov qib C-peptide, cov kws kho mob tuaj yeem paub qhov txawv ntawm hom 1 thiab hom 2 ntshav qab zib, coj kev txiav txim siab kho mob, thiab saib xyuas kev kho mob zoo.

Kev ntsuas cov qib C-peptide yog qhov tseem ceeb rau kev kuaj mob thiab tswj tus kab mob ntshav qab zib. Cov neeg uas muaj tus kab mob ntshav qab zib hom 1 feem ntau muaj cov insulin thiab C-peptide qis lossis tsis pom vim yog lub cev tiv thaiv kab mob tawm tsam cov beta cell uas tsim insulin. Ntawm qhov tod tes, cov neeg uas muaj tus kab mob ntshav qab zib hom 2 yuav muaj cov qib C-peptide ib txwm lossis siab vim tias lawv lub cev tsim insulin tab sis tsis kam rau nws cov teebmeem. Kev saib xyuas cov qib C-peptide hauv cov neeg mob, xws li cov neeg uas tau hloov islet cell, tuaj yeem muab cov kev nkag siab zoo rau kev ua tiav ntawm cov txheej txheem kho mob.

Cov kev tshawb fawb kuj tau tshawb nrhiav txog cov txiaj ntsig tiv thaiv ntawm C-peptide rau ntau yam nqaij. Qee qhov kev tshawb fawb qhia tias C-peptide muaj cov khoom tiv thaiv kev o uas tuaj yeem pab txo cov teeb meem cuam tshuam nrog ntshav qab zib, xws li kev puas tsuaj ntawm cov hlab ntsha thiab lub raum. Txawm hais tias C-peptide nws tus kheej tsis cuam tshuam ncaj qha rau cov ntshav qab zib, nws ua haujlwm ua lub cim qhia tseem ceeb rau kev tswj ntshav qab zib thiab kho cov phiaj xwm kho mob rau tus kheej cov kev xav tau. Yog tias koj xav nkag siab tob txog ntshav qab zib, ua raws lixov xwm lag luammuaj feem cuam tshuam nrog kev kho mob thiab kev nce qib hauv kev kho mob tuaj yeem muab cov kev nkag siab tseem ceeb rau cov kws tshaj lij thiab cov neeg mob.
