N-Acetyl-L-aspartic Acid丨CAS 997-55-7

N-Acetyl-L-aspartic acid (NAA) is an important naturally occurring derivative of the amino acid aspartic acid, widely used in neuroscience and biomedical research. It is primarily utilized as a biomarker for neuronal health and density in magnetic resonance spectroscopy (MRS) studies, providing insights into brain metabolism, development, and neurodegenerative disorders. NAA is employed in research investigating conditions such as multiple sclerosis, Alzheimer's disease, Parkinson's disease, traumatic brain injury, and psychiatric disorders. Beyond neuroscience, it is used in metabolic studies to explore amino acid pathways, energy metabolism in the central nervous system, and the role of N-acetylated amino acids in cellular physiology. The compound is also used as a standard or reference in analytical chemistry and biochemical assays.

N-Acetyl-L-aspartic acid offers several advantages due to its stability, biological relevance, and analytical utility. It is a water-soluble, chemically stable compound that allows precise quantification in biological samples. Its role as a specific neuronal metabolite enables researchers to non-invasively monitor neuronal integrity and metabolic changes using MRS, facilitating early diagnosis and longitudinal studies of neurodegeneration. NAA's compatibility with standard laboratory techniques, including HPLC and mass spectrometry, supports reproducible results in both clinical and preclinical research. Additionally, its involvement in key biochemical pathways makes it a valuable tool for mechanistic studies of neuronal function and energy metabolism.
