Ko te C-peptide (C-peptide) me te insulin (insulin) he ngota e rua e hangaia ana e ngā pūtau moutere pancreatic i te wā e hangaia ana te insulin. Te rerekētanga pūtake: Ko te C-peptide he hua taha o te hanganga insulin e ngā pūtau moutere. Ina hangaia te insulin, ka hangaia te C-peptide i te wā kotahi. Nō reira, ka taea anake te hanga C-peptide i roto i ngā pūtau moutere, ā, kāore e hangaia e ngā pūtau i waho o ngā moutere. Ko te insulin te homoni matua e hangaia ana e ngā pūtau moutere pancreatic, ā, ka tukuna ki roto i te toto, e whakahaere ana i ngā taumata huka toto, e whakatairanga ana i te mimiti me te whakamahinga o te hukahuka. Te rerekētanga mahi: Ko te mahi matua o te C-peptide ko te pupuri i te taurite i waenga i te insulin me ngā kaiwhakawhiwhi insulin, me te whai wāhi ki te hanganga me te huna o te insulin. Ka taea e te taumata o te C-peptide te whakaata ā-kore i te āhua mahi o ngā pūtau moutere, ā, ka whakamahia hei tohu hei aromatawai i te mahi a ngā moutere. Ko te insulin te homoni matua e pākia ana, e whakatairanga ana i te mimiti me te whakamahinga o te hukahuka e ngā pūtau, e whakaiti ana i te kukū huka toto, ā, e whakahaere ana i te tukanga pākia o te ngako me te pūmua. Te rerekētanga kukū toto: He pumau ake ngā taumata toto C-peptide i ngā taumata insulin nā te mea ka puhoi ake te whakakorenga. He maha ngā āhuatanga e pāngia ana te kukū o te insulin i roto i te toto, tae atu ki te kai e kainga ana i roto i te ara kai, te mahi a ngā pūtau moutere, te ātete ki te insulin, me ētahi atu. Hei whakarāpopototanga, ko te C-peptide he hua taha o te insulin e whakamahia ana hei aromatawai i te mahi a ngā pūtau moutere, ko te insulin ia te homoni matua e whakamahia ana hei whakahaere i te toto.
