C-peptide (C-peptide) thiab insulin (insulin) yog ob lub molecule tsim los ntawm cov hlwb pancreatic islet thaum lub sijhawm tsim insulin. Qhov sib txawv ntawm qhov chaw: C-peptide yog cov khoom lag luam ntawm kev tsim insulin los ntawm cov hlwb islet. Thaum insulin raug tsim, C-peptide raug tsim tib lub sijhawm. Yog li ntawd, C-peptide tsuas yog tuaj yeem tsim tau hauv cov hlwb islet thiab yuav tsis tsim los ntawm cov hlwb sab nraud ntawm cov islets. Insulin yog cov tshuaj hormones tseem ceeb uas tsim los ntawm cov hlwb pancreatic islet thiab tso tawm rau hauv cov ntshav, uas tswj cov ntshav qab zib thiab txhawb kev nqus thiab siv cov piam thaj. Qhov sib txawv ntawm kev ua haujlwm: Lub luag haujlwm tseem ceeb ntawm C-peptide yog kom tswj tau qhov sib npaug ntawm insulin thiab insulin receptors, thiab koom nrog kev tsim thiab kev tso tawm ntawm insulin. Qib ntawm C-peptide tuaj yeem cuam tshuam tsis ncaj qha rau lub xeev ua haujlwm ntawm cov hlwb islet thiab siv ua qhov ntsuas los ntsuas kev ua haujlwm ntawm cov islets. Insulin yog cov tshuaj hormones tseem ceeb, uas txhawb kev nqus thiab siv cov piam thaj los ntawm cov hlwb, txo cov ntshav qab zib concentration, thiab tswj cov txheej txheem metabolic ntawm cov rog thiab protein. Qhov sib txawv ntawm cov ntshav concentration: C-peptide cov ntshav theem ruaj khov dua li cov insulin theem vim tias nws raug tshem tawm qeeb dua. Cov ntshav ntawm cov tshuaj insulin raug cuam tshuam los ntawm ntau yam, suav nrog kev noj zaub mov hauv txoj hnyuv, kev ua haujlwm ntawm cov hlwb islet, kev tsis kam insulin, thiab lwm yam. Hauv kev xaus, C-peptide yog cov khoom seem ntawm insulin siv los ntsuas kev ua haujlwm ntawm cov hlwb islet, thaum insulin yog cov tshuaj hormones metabolic tseem ceeb siv los tswj cov ntshav.
