\r\n Tyrosine, discovered in 1846 by Liebig, is (along with phenylalanine and \r\n tryptophan) one of the aromatic amino acids. <\/strong>Of the three, it is \r\n the only non-essential one because it can be synthesised by \r\n phenylalanine. Intestinal absorption of these amino acids depends on \r\n several transporters: tyrosine can use the neutral amino acid \r\n transporter (isoleucine, valine, and leucine) and also the basic amino \r\n acid transporter (histidine, lysine, arginine, and ornithine), which can \r\n be a problem for its assimilation under certain conditions.\r\n <\/p>\r\n

\r\n Tyrosine is involved in the synthesis of catecholamines: adrenaline, \r\n noradrenaline, DoPA and dopamine. It acts as a precursor of melanin \r\n (pigment of the skin, hair and iris) and thyroid hormones.\r\n <\/p>\r\n

\r\n TYROSINE AND SPORT\r\n <\/h2>\r\n

\r\n During high-intensity exercise, its plasma value can increase by 10 to \r\n 15%. This increase is thought to be directly related to intramuscular \r\n protein catabolism. This increase in plasma from active muscles is a \r\n good indication of local protein catabolism.\r\n <\/p>\r\n

\r\n Tyrosine's involvement in the synthesis of catecholamines (adrenaline \r\n and dopamine in particular) can help overtrained athletes through its \r\n fatigue and stress fighting capabilities. It also raises the mental \r\n concentration threshold due to its properties as a dopamine precursor \r\n (see presentation below). Tyrosine can also be useful for those who wish \r\n to lose weight. By stimulating the production of thyroxine by the \r\n thyroid gland, it will enable the latter to influence the basic \r\n metabolism.\r\n <\/p>\r\n

    \r\n DOPAMINE\r\n <\/h2>\r\n

    \r\n Often referred to as the mood barometer or pleasure molecule, dopamine \r\n is a neurotransmitter derived from tyrosine, a member of the \r\n catecholamines. Produced in the neuronal cells of the central nervous \r\n system (CNS), it increases the diameter of the arteries of the heart, \r\n intestine and especially the kidneys. it inhibits the production of \r\n prolactin. in therapy, it is used for its stimulating action on the \r\n cardiovascular system.\r\n <\/p>\r\n

    \r\n The first studies concerning the role of dopamine in the sensation of \r\n pleasure had shown in animals an increase in dopamine in certain regions \r\n of the brain when the latter were engaged in gratifying activities. More \r\n recent evidence shows that dopamine release can be triggered simply by \r\n the environment associated with the reward, without the reward even \r\n being present.\r\n <\/p>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
