What Liraglutide is
Liraglutide is built on human GLP-1 with one amino-acid substitution and a C16 fatty acid attached through a glutamic-acid spacer. The fatty acid lets it bind albumin in blood, which protects it from rapid clearance. Semaglutide later extended the same design idea.
Because it has been in clinical use since 2009, liraglutide has one of the longest published records among GLP-1 agonists, and it is a common comparator in studies of newer incretin peptides.
What the research literature studies
- GLP-1 receptor binding and signalling in cell-based assays
- Albumin binding and the effect of fatty-acid acylation on peptide stability
- Use as a comparator when characterising newer incretin analogues
Evidence rating: 5/5
Approved drug, phase 3 trials. Approved medicine backed by large randomised programmes, including cardiovascular outcome trials. See our methodology for how levels are assigned.
- Outcome data come from the branded medicines, not from research-grade material.
- Acylated peptides need intact-mass analysis, not only HPLC purity, to confirm identity.
Regulatory status
Liraglutide is authorised as a prescription medicine by the MHRA, EMA and FDA under several brand names. Research-grade material is not that medicine, is not evaluated by any regulator, and must not be used in people or animals.

Liraglutide FAQ
How does liraglutide differ from semaglutide?
Both are acylated GLP-1 analogues that act on the GLP-1 receptor only. Semaglutide has a different N-terminal substitution and a longer fatty-diacid linker, which gives it a half-life of about a week compared with roughly 13 hours for liraglutide. See the comparison page.
Is liraglutide a peptide or a protein?
A peptide. It has 31 amino acids plus a fatty-acid side chain.
Where can I buy Liraglutide for research?
Nordapep does not currently list Liraglutide. You can ask Nordapep about availability, or compare related compounds that are in stock.
Is Liraglutide approved?
Liraglutide is authorised as a prescription medicine by the MHRA, EMA and FDA under several brand names. Research-grade material is not that medicine, is not evaluated by any regulator, and must not be used in people or animals.
