WebOct 21, 2024 · It is envisaged that proinsulin firstly forms there, soluble Zn 2+ -stabilized hexamers, which are finally processed into a fully functional, mature 51 amino acid two-chain insulin molecule that is still held in the Zn 2+ -maintained hexamer [ 4 – 7 ]. WebProinsulin is post-translationally cleaved into two chains (peptide A and peptide B) that are covalently linked via two disulfide bonds and one molecule of C-peptide. Insulin …
