N-acylethanolamines (NAEs) are bioactive lipid molecules present in animals and plants. N-acylethanolamine-hydrolyzing acid amidase (NAAA), a heterodimeric lysosomal enzyme is able to hydrolyse NAEs to their respective fatty acids (FAs) and ethanolamine (ETA). The NAEs N-arachidonoylethanolamine (anandamide), N-palmitoylethanolamine, and N-oleoylethanolamine possess cannabimimetic activity, anti-inflammatory and analgesic activities, and anorexic activity, respectively. NAAA can mediate their endogenous levels and shows greatest affinity for N-palmitoylethanolamine (Hong et al. 1999, Tsuboi et al. 2005).
