    Liraglutide peptide: Metabolic Research research guide

    In short: Liraglutide is a GLP-1 receptor agonist: a 31-residue analogue of GLP-1(7-37) with an Arg34 substitution and a C16 palmitoyl-γ-glutamate side chain on Lys26 that promotes albumin binding. It is studied in preclinical (cell and animal) research and is supplied strictly for laboratory use, not for human or clinical use.

    Not medical advice. Liraglutide is a research compound. This guide does not provide dosing, diagnosis, therapy recommendations, or claims about effects in humans.

    Compound Liraglutide Research class Metabolic Research Available pack sizes 10 × 5 mg, 10 × 10 mg, 10 × 30 mg Storage Lyophilised powder: store in freezer (−20 °C). Reconstituted: refrigerate 1–6 °C, away from sunlight.

    Details and limits sit in the sections below. Research use only. No unsupported scientific claims are added here.

    What Liraglutide is

    Liraglutide is a 31-residue acylated GLP-1 receptor agonist: native GLP-1(7-37) with one amino-acid substitution and a C16 fatty-acid side chain that binds serum albumin.

    One-paragraph overview from our research datasheet. Still scientific, but faster to read than the full mechanism list below.

    Liraglutide is a GLP-1 receptor agonist: a 31-residue analogue of GLP-1(7-37) with an Arg34 substitution and a C16 palmitoyl-γ-glutamate side chain on Lys26 that promotes albumin binding.

    Research contexts

    Peer-reviewed papers discuss Liraglutide in specific lab settings. The points below reflect research questions, not health claims.

    Research vs. personal use: Literature describes experiments in cells and animals. That is distinct from real-world use. Our products are for laboratory research only.

    Typical study contexts

  • Incretin pathways, food intake and glucose handling in rodent models.
  • Some drug-class molecules have clinical trials. Those are distinct from catalogue research use.
  • 31-residue acylated GLP-1(7-37) analogue: Arg34 substitution and a C16 palmitoyl-γ-glutamate on Lys26.
  • Fatty-acid chain designed for serum-albumin binding; fatty-acid length is the main determinant of protraction in the structure-activity work.
  • GLP-1 receptor potency characterised in cloned-receptor assays.
  • Cell-level work on cytokine- and fatty-acid-induced apoptosis in primary islets (cAMP and PI3K dependent).
  • Why Metabolic Research research matters

    Metabolic-research peptides are studied for incretin-receptor pharmacology and energy-balance endpoints. The literature reports mechanisms and study endpoints, not guidance for any use.

    Mechanisms (technical review)

    Our datasheet lists mechanistic themes from preclinical work. These are research endpoints, not health claims.

  • Common Questions People Are Asking

    What is liraglutide?

    Liraglutide is a 31-residue GLP-1 receptor agonist: native GLP-1(7-37) with an Arg34 substitution and a C16 palmitoyl-γ-glutamate on Lys26 that binds serum albumin. This page supplies it as laboratory research material only.

    Is the material you supply the same as the approved medicine?

    No. The compound is approved as a medicine in some jurisdictions under the originator's brand names. The research material supplied here is not one of those products, has no published analytical report yet, and is not for human or veterinary use.

    Does published clinical research apply to this material?

    No. Published clinical findings relate to the investigational and approved materials and the protocols used in those studies. They do not establish the safety, efficacy, intended use or clinical equivalence of New-U research material, so they are not summarised on this page.

    How does liraglutide differ from semaglutide?

    Both are acylated GLP-1 analogues with Arg34 and a fatty acid on Lys26. Semaglutide has an additional Aib8 substitution and a longer chain, and was designed after liraglutide. In the discovery paper it bound the receptor with three-fold lower affinity than liraglutide and bound albumin more strongly.

    Is it legal to buy liraglutide for research?

    Liraglutide is a prescription medicine in some jurisdictions; the material supplied here is laboratory research material for in-vitro and preclinical use only, is not one of those medicines, and is not for human or veterinary use. Regulatory requirements vary by product, intended use and jurisdiction, and purchasers are responsible for ensuring that acquisition and use of research material complies with applicable requirements.

    Is there a Certificate of Analysis for liraglutide?

    Not yet. No independent analytical report has been published for this material, so no purity figure is quoted.

    Is this page medical advice? Can I use Liraglutide for my health?

    No, and no. This article is educational only. We do not provide dosing, medical recommendations, or health claims. Our products are sold strictly for laboratory research, not for personal use of any kind.

    Where do I find Liraglutide specs, purity certificates and pricing?

    Open the shop listing via “View product details.” There you will see concentration, purity grade, and available SKUs with current pricing. No current Certificate of Analysis is published for Liraglutide yet; published certificates are listed at /coa.
