Biogenic amines
A group of chemical substances resulting from the decarboxylation of amino acids. Histamine is the best-known biogenic amine.
Biogenic amines are organic compounds that are formed in food or in the body by decarboxylation (cleavage of CO2) of the respective amino acids. Among the best known are histamine, tyramine, putrescine and cadaverine. In the context of HIT, they are crucial because their excessive intake or reduced ability of the body to break them down can lead to symptoms of intolerance.
