A biogenic amine is a biogenic substance with one or more amine groups. They are basic nitrogenous compounds formed mainly by decarboxylation of amino acids or by amination and transamination of aldehydes and ketones. Biogenic amines are organic bases with low molecular weight and are synthesized by microbial, vegetable and animal metabolisms ...
Biogenic amines (BA) are organic compounds commonly found in food, plants and animals, as well as microorganisms that are attributed with the production of BAs. They are formed as an effect of a chemical process: the decarboxylation of amino acids.
Biogenic amines are small cationic monoamines that function broadly as neurotransmitters/neuromodulators across all animal phyla, including flatworms. The most common biogenic amines are serotonin, histamine and several types of tyrosine derivatives including dopamine, noradrenaline and phenolamines (octopamine and tyramine).
There are five established biogenic amine neurotransmitters: the three catecholamines—dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline)—and histamine and serotonin (see Figure 6.3).
Biogenic amines (BAs) are among the most common nitrogenous compounds, widely present in plants, microbes, and animal cells. Although BAs play an important role in regulating a number of important biological functions in the human body, overuse of certain bases can cause serious toxicological effects.
Nov 7, 2018 · Biogenic amines are low molecular weight organic nitrogen compounds. They are formed by the decarboxylation of amino acids or by amination and transamination of aldehydes and ketones during normal metabolic processes in living cells and therefore are ubiquitous in animals, plants, microorganisms, and humans.
Nov 1, 2019 · Biogenic amines (BAs) are important nitrogenous compounds formed mainly by decarboxylation of amino acids or by amination and transamination of aldehydes and ketones. In food and beverages, biogenic amines are formed by the enzymes of raw material and generated by microbial decarboxylation of amino acids.
Biogenic amines are decarboxylation products of amino acids and are formed during fermentation (e.g., cheese ripening and wine fermentation) and decomposition of protein, usually fish. These biogenic amines include histamine, tyramine, cadaverine, putrecine, and related metabolites.
The biogenic amines encompass multiple neurotransmitters, including serotonin, histamine, dopamine, norepinephrine, and epinephrine. Included within the biogenic amines is a separate group of neurotransmitters, the catecholamines. This chapter will provide information for only serotonin and histamine.
Mar 23, 2010 · The most common biogenic amines found in foods are histamine, tyramine, cadaverine, 2-phenylethylamine, spermine, spermidine, putrescine, tryptamine, and agmatine. In addition octopamine and dopamine have been found in meat and meat products and fish.
