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 ...
Due to the narrow gap between their ability to block the biogenic amine uptake pumps versus the inhibition of fast sodium channels, even a modest overdose of one of the TCAs could be lethal. TCAs were, for 25 years, the leading cause of death from overdoses in many countries.
Crude oil, a transformed biogenic substance Natural gum, a secretion from Hevea brasiliensis. A biogenic substance is a product made by or of life forms. While the term originally was specific to metabolite compounds that had toxic effects on other organisms, [1] it has developed to encompass any constituents, secretions, and metabolites of plants or animals.

Tyramine is a biogenic amine produced as a (generally undesirable) byproduct during the fermentation of certain tyrosine-rich foods. It is rapidly metabolized by MAO-A in those not taking MAO-inhibiting drugs. Individuals sensitive to tyramine-induced hypertension may experience an uncomfortable, yet fleeting, increase in blood pressure after ...
Amine. In chemistry, amines (/ ə ˈ m iː n, ˈ æ m iː n /, [1] [2] UK also / ˈ eɪ m iː n / [3]) are compounds and functional groups that contain a basic nitrogen atom with a lone pair.Formally, amines are derivatives of ammonia (NH 3 (in which the bond angle between the nitrogen and hydrogen is 170°), wherein one or more hydrogen atoms have been replaced by a substituent such as an ...
Histamine, a biogenic amine, involves many physiological functions, including the immune response, gastric acid secretion, and neuromodulation. However, its rapid metabolism makes it challenging to measure histamine levels directly in plasma.

Hordenine is an alkaloid of the phenethylamine class that occurs naturally in a variety of plants, taking its name from one of the most common, barley (Hordeum species). ). Chemically, hordenine is the N-methyl derivative of N-methyltyramine, and the N,N-dimethyl derivative of the well-known biogenic amine tyramine, from which it is biosynthetically derived and with which it shares some ...
