Coupled chains : A fully synthetic single‐chain branched depsipeptide precursor lacking a proinsulin‐like tethering of the A and B chains leads, by oxidative folding to the insulin characteristic cystine topology and by subsequent saponification of the ester bond, to the target two‐chain insulin molecule with high efficiency (see picture; violet/blue A/B chain, yellow cystine units).
