More Info:
Aside from these general functions, individual amino acids also have specific functions in many aspects of human physiology and biochemistry. Tyrosine is a precursor of important neurotransmitters in the brain, such as dopamine, epinephrine (adrenaline) and norepinephrine (noradrenaline). The synthesis of these neurotransmitters is limited by the rate of tyrosine entry from plasma into the brain. For example, low plasma levels of tyrosine, as can result from the use of oral contraceptive drugs, cause lower norepinephrine synthesis which is associated with mood changes and other neurological signs.
Tyrosine is also a precursor of the thyroid hormones triiodothyronine and thyroxine. In the thyroid gland, these hormones are synthesized from a precursor protein called thyroglobulin, which is a large protein rich in tyrosine residues that are reacted with iodine. When needed, thyroid hormones are released via hydrolysis from thyroglobulin. Thyroglobulin functions as storage for the thyroid hormones; a several weeks’ supply of these hormones exists in the normal thyroid gland. Once released, thyroid hormones act via specific cell receptors to increase oxygen consumption and basal metabolic rate. L-Tyrosine is a conditionally essential amino acid that can be manufactured by the body from the essential amino acid phenylalanine. Therefore, adequate tyrosine production depends on a sufficient supply of phenylalanine in the diet.
