Common Name | 3-Methoxytyrosine |
---|
Description | 3-Methoxytyrosine, also known as 3-O-methyldopa or vanilalanine, belongs to the class of organic compounds known as tyrosine and derivatives. Tyrosine and derivatives are compounds containing tyrosine or a derivative thereof resulting from reaction of tyrosine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. 3-Methoxytyrosine is one of the main biochemical markers for Aromatic L-amino acid decarboxylase (AADC, EC4.1.1.28) Deficiency, an inborn error of metabolism that affects serotonin and dopamine biosynthesis. Chronically high levels of 3-methoxytyrosine are associated with aromatic L-amino acid decarboxylase (AADC, 28) deficiency, an inborn error of metabolism that affects serotonin and dopamine biosynthesis. 3-Methoxytyrosine is a potentially toxic compound. 3-Methoxytyrosine, with regard to humans, has been found to be associated with several diseases such as epilepsy, early-onset, vitamin b6-dependent and pyridoxamine 5-prime-phosphate oxidase deficiency; 3-methoxytyrosine has also been linked to several inborn metabolic disorders including sepiapterin reductase deficiency and aromatic l-amino acid decarboxylase deficiency. |
