aspartoacylase is a key enzyme in the human central nervous system. N-Acetyl-L-aspartate is a precursor for the synthesis of the dipeptide N-acetylaspartyl-glutamate, which participates in the neuromodulation of metabotropic and NMDA receptors (NMDA is N-methyl-D-aspartate), regulates the intracellular pressure in neurons and is involved in the energy generation from glutamate anions in neuronal mitochondria. N-Acetyl-L-aspartate is a source of acetyl groups for the construction of myelin sheath in the brain. Therefore, maintenance of the N-acetyl-L-aspartate level ensures proper development and functions of white matter
