N-acetylaspartate Metabolic Pathway (NAA Metabolic Pathway)

The N-acetylaspartate (NAA) metabolic pathway centers on the synthesis, utilization, and degradation of NAA—a highly abundant metabolite in the brain and brown adipose tissue (BAT). This pathway is crucial for neuronal health, myelin lipid synthesis, energy metabolism, and metabolic adaptation in both neural and non-neural tissues. Key enzymes include Aspartate N-acetyltransferase (Asp-NAT; gene: NAT8L) and Aspartoacylase (ASPA). Abnormalities are linked with neurological diseases such as Canavan disease due to ASPA mutations leading to toxic accumulation of NAA. Changes in peripheral tissues like BAT may influence systemic energy balance/metabolic health—potential target for anti-obesity therapies via modulation of thermogenic capacity.
