"In dopaminergic cells in the brain, tyrosine is converted to l-dopa by the enzyme tyrosine hydroxylase (TH). TH is the rate-limiting enzyme involved in the synthesis of the neurotransmitter dopamine. Dopamine can then be converted into the catecholamines norepinephrine (noradrenaline) and epinephrine (adrenaline).

The thyroid hormones triiodothyronine (T3) and thyroxine (T4) in the colloid of the thyroid also are derived from tyrosine."

"A number of studies have found tyrosine to be useful during conditions of stress, cold, fatigue,[15] loss of a loved one such as in death or divorce, prolonged work and sleep deprivation,[16][17] with reductions in stress hormone levels,[18] reductions in stress-induced weight loss seen in animal trials,[15] improvements in cognitive and physical performance[13][19][20] seen in human trials; however, because tyrosine hydroxylase is the rate-limiting enzyme, effects are less significant than those of L-DOPA."
