The B-chain C-terminal {region|area} of insulin has been mutated or modified {to achieve|to attain} {improved|enhanced} therapeutic efficacies. For ex-ample, all FDA-approved insulin analogs have altered C-terminal segments, which {leads to|results in} {improved|enhanced} pharmacokinetic prop-erties and {provide|offer|supply|give|present|deliver} {significant|substantial|considerable|important} clinical {benefits|advantages|rewards|positive aspects|added benefits} on blood sugar regulation.
