The endocannabinoid anandamide (N-arachidonoylethanolamine) and other bioactive long-chain N-acylethanolamines are thought to be formed from their corresponding N-acylphosphatidylethanolamines by a specific phospholipase D (NAPE-PLD) in the brain as well as other tissues. However, regional distribution of NAPE-PLD in the brain
