N-Acetylaspartate (NAA)

NAA is the second-most-concentrated molecule in the brain after the amino acid glutamate, synthesized in the mitochondria from the amino acid aspartic acid and acetyl-coenzyme A.

The various functions served by NAA are under investigation, but the primary proposed functions include:

Neuronal osmolyte that is involved in fluid balance in the brain

Source of acetate for lipid and myelin synthesis in oligodendrocytes, the glial cells that myelinate neuronal axons

Precursor for the synthesis of the neuronal dipeptide N-Acetylaspartylglutamate

Contributor to energy production from the amino acid glutamate in neuronal mitochondria
