Tyrosine
From MEpedia, a crowd-sourced encyclopedia of ME and CFS science and history
Tyrosine, an amino acid, is a precursor to the neurotransmitter dopamine. It is converted to L-DOPA by the enzyme tyrosine hydroxylase.[citation needed]
It is also a precursor to the thyroid hormones triiodothyronine (T3) and thyroxine (T4)
Tyrosine and its precursor phenylalanine are required for the synthesis of coenzyme Q10
ME/CFS[edit | edit source]
Reduced levels of plasma tyrosine have been found in ME/CFS patients.[1][2]
