3-O-Methyl-DL-DOPA  (Synonyms: 3-Methoxytyrosine)

3-O-Methyl-DL-DOPA is an endogenous metabolite present in Cerebrospinal_Fluid that can be used for the research of Epilepsy, Purine Nucleoside Phosphorylase Deficiency and Aromatic L Amino Acid Decarboxylase Deficiency^[1][2][3][4].

Endogenous metabolites is defined as those that are annotated by Kyoto Encyclopedia of Genes and Genomes as substrates or products of the ~1900 metabolic enzymes encoded in our genome. It is clear in the body of literature that there are documented toxic properties for many of these metabolites^[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
