Four-disulfide insulin has similar bioactivity to native human insulin

Scientists in the US have made insulin more thermally stable, yet just as potent, by adding an extra disulfide bond. The insulin analogue could be beneficial for diabetes patients who struggle to access refrigerators to store their medication.
