C-peptide, tseem hu ua txuas peptide, yog cov amino acid tseem ceeb hauv kev tsim cov tshuaj insulin. Nws raug tso tawm los ntawm pancreas nrog rau cov tshuaj insulin thiab ua tus cim tseem ceeb rau kev ntsuas kev ua haujlwm ntawm pancreatic. Thaum insulin tswj cov ntshav qab zib, C-peptide ua lub luag haujlwm sib txawv thiab tseem ceeb hauv kev nkag siab txog ntau yam kev noj qab haus huv, tshwj xeeb yog ntshav qab zib. Los ntawm kev ntsuas qib C-peptide, cov kws kho mob tuaj yeem sib txawv ntawm hom 1 thiab hom 2 mob ntshav qab zib, qhia kev txiav txim siab kho mob, thiab saib xyuas kev kho mob zoo.

Kev ntsuas qib C-peptide yog qhov tseem ceeb hauv kev kuaj mob thiab tswj ntshav qab zib. Cov neeg mob ntshav qab zib hom 1 feem ntau muaj cov tshuaj insulin thiab C-peptide qis lossis tsis tuaj yeem kuaj pom vim yog lub cev tsis muaj zog ntawm cov tshuaj insulin-tsim beta hlwb. Ntawm qhov tod tes, cov tib neeg muaj ntshav qab zib hom 2 tuaj yeem muaj qhov qub lossis nce qib C-peptide vim tias lawv lub cev tsim cov tshuaj insulin tab sis tiv taus nws cov teebmeem. Kev saib xyuas cov qib C-peptide hauv cov neeg mob, xws li cov uas tab tom hloov cov islet cell, tuaj yeem muab kev nkag siab zoo rau kev ua tiav ntawm cov txheej txheem kho mob.

Cov kev tshawb fawb kuj tau tshawb fawb txog qhov muaj peev xwm tiv thaiv C-peptide ntawm ntau cov ntaub so ntswg. Qee qhov kev tshawb fawb qhia tias C-peptide tuaj yeem muaj cov tshuaj tiv thaiv kab mob uas tuaj yeem pab txo cov teeb meem cuam tshuam nrog ntshav qab zib, xws li paj hlwb thiab lub raum puas. Txawm hais tias C-peptide nws tus kheej tsis cuam tshuam ncaj qha rau cov ntshav qabzib, nws ua haujlwm raws li biomarker tseem ceeb rau kev tswj ntshav qab zib thiab kho cov phiaj xwm kho mob rau tus kheej xav tau. Yog tias koj xav delve tob rau hauv kev nkag siab txog ntshav qab zib, ua rawsxov xwm lag luamcuam tshuam nrog kev kho mob thiab kev kho mob nce qib tuaj yeem muab kev pom zoo rau ob tus kws tshaj lij thiab cov neeg mob.
