Research entry
GLP-1 (S)
The single-receptor version of the same family
In plain terms
GLP-1 (S) mimics a hormone the gut releases after eating. Research on this compound class has examined effects on insulin release, appetite signalling and gastric emptying. Supplied as an analytical reference standard, not for administration.
Research overview
GLP-1 (S) is semaglutide, an analogue acting on the GLP-1 receptor alone. It is the most-studied compound in the incretin class and the comparator most newer research is measured against. The literature covers insulin release in response to glucose, gastric emptying and appetite signalling, and now spans a large body of human trials.
What has been studied
- 1
The single-receptor baseline
GLP-1 (S) acts on the GLP-1 receptor alone. It is the most-studied compound in the incretin class and the comparator most of the newer research measures against.
- 2
Glucose and appetite signalling
Research has looked at insulin release in response to glucose, the rate at which the stomach empties, and appetite signalling in the brain.
- 3
Combination research
A large body of newer work pairs it with amylin agonists such as cagrilintide, studying whether the two together behave differently from either alone.
