N-terminally truncated GLP-1 and exendin-4 peptides lacking the first 8 amino acids (GLP-1(1536) and exendin(939)), exhibit similar affinities in published studies 31 , to their corresponding full-length peptides in the absence of G protein, providing further support that the influence of G s on peptide affinity is predominantly related to interactions of the N-terminus with the TMD
At the N-terminus, the Tyr1 of Tirzepatide makes Van der Waals contact with the receptor residues, the Glu3 forms an ionic bond with Arg183 and a network of hydrogen bonds with Tyr145 and Ser381 of the receptor
Common Side Effects of Ozempic Despite its benefits, Ozempic is associated with several side effects, most of which are mild but can be uncomfortable

GLP-1 antagonists block GLP-1 receptors, preventing the hormone from triggering these effects
