Subcutaneous deposition was also an important part of the mechanism of protraction here, facilitated by the fatty acid in insulin degludec leading to self-assembly into multi-hexamers, but insulin degludec also has a longer intravenous half-life than insulin detemir ( The Discovery of Liraglutide GLP-1 is a 30 amino acid peptide hormone with a short half-life (1.5 min following intravenous dosing and 1.5 h following subcutaneous dosing in humans) ( In attempts to prolong the half-life of GLP-1 and develop a suitable compound for therapeutic use, some pharmaceutical companies (32) chose to optimize the exendin-4 peptide (a naturally occurring peptide obtained from Heloderma lizard venom, with 53% homology to human GLP-1), which leads to an intravenous half-life of ~30 min (3335)
