Anandamide (ANA), also referred to as N-arachidonoylethanolamine (AEA) is a fatty acid neurotransmitter belonging to the fatty acid derivative group known as N-Acylethanolamine (NAE). Anandamide takes its name from the Sanskrit word ananda, meaning "joy, bliss, delight," plus amide. Anandamide, the first discovered endocannabinoid, engages with the body's endocannabinoid system by binding to the same cannabinoid receptors that THC found in cannabis acts on. Anandamide can be found within tissues in a wide range of animals.[1][2] It has also been found in plants, such as the cacao tree.[3]
Anandamide is derived from the non-oxidative metabolism of arachidonic acid, an essentialomega-6 fatty acid. It is synthesized from N-arachidonoyl phosphatidylethanolamine by multiple pathways.[4] It is degraded primarily by the fatty acid amide hydrolase (FAAH) enzyme, which converts anandamide into ethanolamine and arachidonic acid. As such, inhibitors of FAAH lead to elevated anandamide levels and are being pursued for possible therapeutic use.[5][6]
