this effect appeared to involve interaction of insulin with specific receptors , since insulin analogs exhibiting diminished receptor binding affinity and peripheral bioactivity compared to the native hormone were much less active ( i.e. , insulin much greater than acetyl 3 insulin greater than proinsulin greater than igf-i ) or not active at all ( i.e. , insulin chain a and chain b ) .
