The present invention provides stably crosslinked insulinotropic polypeptides having superior and unexpected benefits in the treatment of conditions involving abnormal glucose homeostasis, e.g., type 2 diabetes and conditions relating to type 2 diabetes. Such benefits include, but are not limited to, extended polypeptide half-life, enhanced alpha-helicity, improved thermal stability and protease resistance, increased functional activity and pharmacologic properties, improved bioavailability when administered by any route, and improved bioavailability and gastrointestinal absorption when delivered orally, as compared to the corresponding unmodified polypeptides. The invention also provides compositions for administering the polypeptides of the invention, as well as methods for preparing and evaluating the polypeptides of the invention.
