What Semaglutide is
Semaglutide is a GLP-1 receptor agonist. A GLP-1 analogue modified for albumin binding and resistance to DPP-4 degradation, giving a long circulating half-life relative to native GLP-1.
Class and mechanism
Semaglutide is a GLP-1 receptor agonist. A GLP-1 analogue modified for albumin binding and resistance to DPP-4 degradation, giving a long circulating half-life relative to native GLP-1.
Where it sits
Incretin compounds are grouped by how many receptors they act at. A single agonist works at GLP-1 alone, a dual agonist adds GIP, and a triple agonist adds glucagon. The receptor count is the clearest way to tell one from another when the names are unfamiliar.
Other names
Semaglutide is also written as GLP-1, Ozempic and Wegovy. The same molecule appears under more than one name, which is worth knowing when comparing listings between suppliers.
Others in the metabolic and GLP-1 range
Semaglutide sits in the metabolic and GLP-1 group. The compounds below share that grouping, which is the useful starting point when comparing one against another: same group means the comparison is like for like, different group usually means it is not.
