L-Tyrosine can be converted by neurons in the brain to dopamine and norepinephrine (noradrenaline), hormones, which are depleted by stress, overwork and certain drugs. By replenishing norepinephrine in the brain, mental energy levels are enhanced and a feeling of contentment often occurs. Because of the liver conversion necessary for L-phenylalanine to have these effects, L-tyrosine is often faster acting. In addition, the conversion step from L-tyrosine to norepinephrine may be enhanced if the cofactors (vitamins B6 and C) are included.
Some of the norepinephrine will also be converted to epinephrine (adrenaline) in the brain’s adrenal medulla by use of S-adenosylmethionine (SAMe) as a methylating agent. Since both norepinephrine and epinephrine can cause smooth muscle (arterial) contraction, care with blood pressure should be taken when supplementing L-phenylalanine or L-tyrosine.
L-tyrosine is also a precursor of two thyroid hormones. D-phenylalanine is unique among amino acids because the D-form (normally not found in life) has biological activity that is different from its L-stereoisomer. D,L-phenylalanine is a 50/50 mixture of the two stereoisomers.
L TYROSINE is an essential free form amino acid, which rapidly crosses the blood-brain barrier. It is a precursor for the neurotransmitters dopamine, norepinephrine, and epinephrine, for thyroid hormones, and for enkephalins, special peptides that subdue messages of physical discomfort. Tyrosine is also a constituent of protein amino sugars (glycosaminoglycans) and amino lipids (glycolipids), special compounds that have important roles throughout the body.
