In summary, food ingestion markedly raises plasma DA sulfate degrees. This may final result from genuine ingestion of l-DOPA, DA, or DA sulfate, from conversion of ingested tyramine to DA, from actions of tyrosinase to generate l-DOPA from the gastrointestinal lumen, what are catecholamines or from amplified release and metabolism of endogenous DA in gastrointestinal lining cells. Tyrosine produced from breakdown of dietary protein can enter sympathetic nerves or other cells containing TH, causing production of l-DOPA outside the house the gastrointestinal tract.
