How a glucagon backbone becomes a once-weekly drug
Survodutide is a glucagon-derived peptide that incorporates potent GLP-1 receptor agonist activity, carrying a greasy fatty-acid tail that lets it cling to blood proteins for days. No source this course rests on describes which residues were changed to reach the GLP-1 receptor, so this unit builds the molecule from what is published, then follows how that tail turns a fast hormone into a drug you inject once a week.
Understanding the acylation trick and the balanced-agonism tuning unlocks everything practical that follows: the weekly rhythm, the slow dose titration, and why the glucagon signal is deliberately kept partial rather than full.
