Overview
Oleoylethanolamide (OEA) is an endogenous fatty acid derivative synthesized in the small intestine from oleic acid. As a bioactive lipid, it functions as a natural satiety signal and metabolic regulator through PPAR-α receptor activation. Discovered in 2001, OEA has gained attention in pharmaceutical and nutraceutical industries for its potential in managing obesity and metabolic disorders. Structurally classified as an N-acylethanolamine, OEA shares biosynthetic pathways with endocannabinoids but exhibits distinct pharmacological effects. Unlike cannabinoids, OEA does not bind to CB1/CB2 receptors, making it a promising target for non-psychoactive therapeutic development.
Physical and Chemical Properties
OEA appears as a white crystalline solid with moderate solubility in organic solvents but negligible water solubility. Its melting point ranges between 90-92°C, characteristic of long-chain fatty acid amides. The compound demonstrates stability under dry, cool conditions but may degrade upon prolonged exposure to light or humidity. Chemically, OEA contains an 18-carbon oleoyl chain (C18:1) linked to ethanolamine via an amide bond. This configuration allows for specific receptor interactions while maintaining membrane permeability. Analytical characterization typically involves HPLC (≥98% purity standard) and mass spectrometry for identity confirmation.
Main Applications
In pharmaceutical research, OEA serves as a reference compound for studying PPAR-α mediated pathways in lipid metabolism and appetite control. Clinical investigations explore its potential for obesity management, with studies showing reduced food intake and body weight in animal models. The nutraceutical industry incorporates OEA in dietary supplements targeting metabolic health, often combined with other bioactive lipids. Industrial applications include use as a biochemical tool in membrane biology research and as a standard in analytical method development for endocannabinoid system studies.
Safety and Storage
As a research chemical, OEA requires handling with appropriate PPE including gloves and safety goggles. While considered low toxicity, material safety data sheets (MSDS) should be consulted for specific hazard information. No severe adverse effects have been reported at typical research dosages. Long-term storage recommendations include protection from moisture (desiccated environment) and oxidation (argon/vacuum sealing). For laboratory use, aliquoting into amber vials at -20°C prevents repeated freeze-thaw cycles that may impact stability. Shipping typically occurs at ambient temperature with desiccant packs.
B2B Procurement Guide
Bulk purchasers should prioritize suppliers with certified Good Manufacturing Practice (GMP) compliance for pharmaceutical-grade material. Key quality metrics include HPLC purity certificates (>98%), heavy metal content analysis, and microbial limits testing. For research institutions, small quantity providers offering analytical standards with certified reference materials (CRMs) are preferable. MOQ (Minimum Order Quantity) typically starts at 1g for high-purity grades, with volume discounts available at 100g+ quantities. Lead times vary from 2-6 weeks depending on customization requirements and regulatory documentation needs.
