biogenic amine, one of a large group of naturally occurring biologically active compounds, most of which act as neurotransmitters. The most dominant, norepinephrine, is involved in such physiologic functions as emotional reactions, memory, sleep, and arousal from sleep. Other biochemicals of the group include three catecholamines: histamine, serotonin, and dopamine. These substances are active in regulating blood pressure, elimination, body temperature, and many other centrally mediated body functions. biogenic having the property of originating in a biological process. biogenic amine an amine neurotransmitter, such as epinephrine, norepinephrine, serotonin or dopamine. endogenous biogenic amines occur naturally in the body, e.g. epinephrine, norepinephrine.

Cerebrospinal fluid and urinary biogenic amines in depressed patients and healthy controls. Both polyamines and biogenic amines are present in food. The production of biogenic amines, such as tyramine and histamine, by more than 30 starter culture bacteria is also under examination, as these amines are highly undesirable in dry sausage. |
