Amines, biogenic
Synonym(s)
DefinitionThis section has been translated automatically.
Primary amines (nitrogen compounds) naturally occurring in plants and animals, which are formed from amino acids by enzymatic decarboxylation. A distinction is made between endogenous and exogenous biogenic amines.
Endogenous amines are produced in the organism in various organs and tissues (adrenalin: adrenal medulla, histamine: liver, mast cells), phenethylamine (brain from the AS phenylalanine).
Exogenous amines are supplied nutritively (e.g. so-called wine allergy).
Biogenic amines themselves are synthesis precursors of biologically relevant substances such as alkaloids (e.g. cadaverine as a decarboxylation product of lysine) or hormones(histamine via histidine decarboxylase from histidine). Furthermore biogenic amines serve as starting products for the synthesis of coenzymes, vitamins and phospholipids.
Some biogenic amines themselves have physiological effects, for example as neurotransmitters (dopamine and noradrenalin from the amino acid DOPA; serotonin from the amino acid 5-hydroxytryptophan; tyramine from the amino acid tyrosine).

OccurrenceThis section has been translated automatically.
Exogenous biogenic amines are found in smaller amounts in almost all foods, especially in tropical fruits(pineapple, avocado, bananas, citrus fruits), but also in tomatoes, walnuts, raspberries, plums and spinach. Larger, possibly toxic quantities can be produced during the microbial decomposition of fish and meat. Furthermore, larger amounts can also be found in foods produced by microbial (bacteria or fungi) processes, such as certain types of cheese, sauerkraut and wine.
Clinical pictureThis section has been translated automatically.
After consumption of food containing large amounts of biogenic amines, acute pseudoallergic reactions (see intolerance reaction below) may occur a few minutes to hours after ingestion, such as: flushing erythema, itching, urticaria, angioedema up to anaphylactic shock, acute rhinitis, acute asthma, diarrhoea symptoms, headaches.
