C-Peptide (C-Peptide) inobatanidza peptide inoumbwa ne31 amino acids ine molecular huremu hunosvika mazana matatu nemakumi maviri nenomwe Daltons. Iyo pancreatic β-masero epancreas anogadzira proinsulin, inova yakareba kwazvo protein chain. Proinsulin yakaputsika kuita zvikamu zvitatu pasi pekuita kwema enzymes, uye zvikamu zvepamberi neshure zvinobatanidzwa zvakare kuti ive insulin, iyo inoumbwa neketani A uye B, nepo chikamu chepakati chakazvimirira uye chinozivikanwa seC-peptide. . Insulin uye C-peptide zvakavanzwa mu equimolar concentrations, uye mushure mekupinda muropa, yakawanda ye insulin haina kuvharwa nechiropa, nepo C-peptide isingawanzo kutorwa nechiropa, pamwe neC-peptide kuderera kunononoka kupfuura insulin. kuwanda kweC-peptide muropa yakakwirira kudarika insulin, kazhinji kanopfuura ka5, saka C-peptide inonyatsoratidza basa repancreatic islet β-cell. Kuyera kweyero yeC-peptide inogona kushandiswa pakurongwa kwechirwere cheshuga mellitus uye kunzwisisa basa repancreatic β-masero evarwere vane chirwere cheshuga mellitus. Chiyero cheC-peptide chinogona kushandiswa kurongedza chirwere cheshuga uye kunzwisisa basa repancreatic β-cell muvarwere vane chirwere cheshuga. Parizvino, nzira dzekuyera C-peptide dzinoshandiswa zvakanyanya mumakiriniki ekurapa dzinosanganisira radioimmunoassay, enzyme immunoassay, electrochemiluminescence, chemiluminescence.
