Ozempic and Wegovy are not exendin-4. While they belong to the same drug class (GLP-1 receptor agonists) and share a common historical origin, they are chemically distinct molecules.
1) Exendin-4 (Exenatide): Sold as Byetta or Bydureon, this drug is a synthetic replica of the peptide found in Gila monster venom. It shares only 53% homology (structural similarity) with human GLP-1.
2) Semaglutide (Ozempic/Wegovy): This is a synthetic analog of human GLP-1, not lizard venom. It shares 94% homology with the human hormone. It was engineered using the knowledge gained from exendin-4 (specifically how to resist enzymatic degradation) but is built on a human template modified with a fatty acid side chain to extend its half-life.
@isabellasg3 Why the HELL do people talk with such certainty about things when they know it can be easily fact-checked using AI???
GTFOH, man... there's enough confusion and misinformation as it is!
