amine

 [am´in, ah´mēn]
an organic compound containing nitrogen.
biogenic amine bioamine.
sympathomimetic a's amines that mimic the actions of the sympathetic nervous system, the group includes the catecholamines and drugs that mimic their actions.
vasoactive a's amines that cause vasodilation and increase small vessel permeability, such as histamine and serotonin.

biogenic amine

n.
Any of a group of naturally occurring, biologically active amines, many of which are neurotransmitters, including norepinephrine, dopamine, and serotonin.

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 physiological 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 amine

Any of the amines produced by living systems, which are involved in intercellular signalling.

Types
• Ethanolamine derivatives—choline, acetylcholine, muscarine.
• Catecholamines—adrenaline/epinephrine, noradrenaline/norepinephrine, dopamine.
• Polyamines—spermine.
• Indolylalkylamines—e.g., tryptamine and serotonin.
• Betaines—carnitine.
• Polymethyline diamines—cadaverine and putrescine.
• Others—histamine, serotonin, tyramine.

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.

In conclusion, (a) high plasma Phe concentrations caused marked in vivo inhibition of erythrocyte-membrane AChE activity in PKU (the latter is reinforced by our studies on the in vitro effect of Phe on AChE), (b) AChE inhibition could affect ACh hydrolysis and its consequences in nervous system functions, (c) high Phe concentrations may explain the decreased concentrations of biogenic amines in PKU, and (d) our data showed for the first time that the evaluation of erythrocyte-membrane AChE activity in relation to biogenic amine blood concentrations could be a useful peripheral marker for evaluation of the effects of high Phe concentrations in the brains of PKU patients.
