2-Arachidonyl Glycerol is primarily known for its role as an endocannabinoid in the human body, where it functions as a signaling molecule in the endocannabinoid system. It binds to cannabinoid receptors, particularly CB1 and CB2, to modulate various physiological processes such as pain sensation, mood regulation, and immune response. In research, it is used to study the mechanisms of the endocannabinoid system and its involvement in neurological disorders, inflammation, and metabolic regulation. Additionally, it has potential therapeutic applications in developing treatments for conditions like chronic pain, anxiety, and neurodegenerative diseases. Its role in lipid signaling pathways also makes it a subject of interest in studies related to cellular communication and homeostasis.
