Tirzepatide has been approved for chronic weight management in adults with obesity or overweight conditions in conjunction with a reduced-calorie diet and increased physical activity

The line between peptide and protein is blurry: while the FDA uses a conservative cut off of 40 a.a., this would exclude insulin (~51 a.a.)

It was discovered in the saliva of the Gila monster, a venomous lizard found in the American southwest, although no one knows why the lizard produces a molecule that replicates the action of GLP-1 when injected twice a day

Two carboxyl groups on a side chain disclosed by patent CN111378028A are naked and are not protected by a protective group, the purity of an intermediate obtained in the subsequent coupling reaction with an Arg34GLP-1 (9-37) main peptide chain is not high, only 67.5 percent is obtained, the yield is seriously reduced, and the pH value in the reaction has a large influence on the side chain modification, so that various byproducts which are difficult to remove are easily generated, such as a double-modified impurity byproduct with both the 26 th position and the end position of the main peptide chain modified and a byproduct with the end position of the main peptide chain modified
