They use in vitro and in vivo experiments to demonstrate the chain-splitting process across A—and B—insulin chains and substantiate their claims with data from the literature. Study data was ...

or SPC-insulin, is better able to maintain its configuration, compared with the conventional two-chain configuration, linked by disulfide bonds which quickly reduce to inactive a- and b- chains ...
