A biogenic amine is a biogenic substance with an amine group. Some prominent examples of biogenic amines include: A biogenic substance is a substance produced by life processes. ... Ammonia Amines are organic compounds and a type of functional group that contain nitrogen as the key atom. ...
Histamine - a substance derived from the amino acid histidine that acts as a neurotransmitter mediating arousal and attention, as well as a pro-inflammatory signal released from mast cells in response to allergic reactions or tissue damage
Tyramine - a substance that is found in many common foods, and is associated with increased blood pressure and headaches
Epinephrine (adrenaline) - an adrenal stress hormone, as well as a neurotransmitter present at lower levels in the brain
Dopamine - a neurotransmitter involved in motivation, reward, addiction, behavioral reinforcement, and coordination of bodily movement
Histamine is a biogenic amine chemical involved in local immune responses as well as regulating physiological function in the gut and acting as a neurotransmitter. ... The general structure of an amino acid molecule, with the amine group on the left and the carboxyl group on the right. ... Histidine is one of the 20 most common natural amino acids, coded for in DNA. Nutritionally, in humans, histidine is considered an essential amino acid, but mostly only in children. ... Chemical structure of D-Aspartic Acid, a common Amino Acid neurotransmitter. ... Inflammation is the first response of the immune system to infection or irritation and may be referred to as the innate cascade. ... Mast cells A mast cell (or mastocyte) is a resident cell of connective tissue that contains many granules rich in histamine and heparin. ... An allergy can refer to several kinds of immune reactions including Type I hypersensitivity in which a persons body is hypersensitised and develops IgE type antibodies to typical proteins. ... Tyramine (4-hydroxy-phenethylamine) is a monoamine compound derived from the amino acid tyrosine. ... Serotonin (5-hydroxytryptamine, or 5-HT) is a monoamine neurotransmitter synthesized in serotonergic neurons in the central nervous system and enterochromaffin cells in the gastrointestinal tract. ... A diagram showing the CNS: 1. ... Catecholamines are chemical compounds derived from the amino acid tyrosine. ... Norepinephrine (INN) or noradrenaline (BAN) is a catecholamine and a phenethylamine with chemical formula C8H11NO3. ...

Biogenicamines are basic nitrogenous low molecular weight compounds with biological activity that may be formed or catabolised during the normal metabolism of animals, plants and micro-organisms.
Amines may be formed by yeasts during the alcoholic fermentation (mostly putrazine); by lactic acid bacteria (LAB) during malolactic fermentation (MLF) and during maturation of wines.
An increase in the levels of biogenicamines usually occurs towards the end of the MLF or during maturation, when lactobacilli and pediococci are the biggest culprits.
