Metabolite Identification
Common NameN-Acetyl-L-aspartic acid
DescriptionN-Acetyl-L-aspartic acid, also known as acetylaspartate or NAA, belongs to the class of organic compounds known as aspartic acid and derivatives. Aspartic acid and derivatives are compounds containing an aspartic acid or a derivative thereof resulting from reaction of aspartic acid at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. N-Acetyl-L-aspartic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). N-Acetyl-L-aspartic acid exists in all living organisms, ranging from bacteria to humans. N-acetyl-L-aspartic acid can be converted into acetic acid and L-aspartic acid; which is mediated by the enzyme aspartoacylase. In cattle, N-acetyl-L-aspartic acid is involved in the metabolic pathway called the aspartate metabolism pathway. N-Acetyl-L-aspartic acid is a potentially toxic compound.
