Catecholamines are the chemicals released by your brain, nerve cells, and adrenal glands that act as modulators of the stress response, also known as the fight-or-flight response. Three commonly known ones are epinephrine (adrenaline), norepinephrine, and dopamine.

She further explained COMT was a key enzyme in the metabolism of catecholamines, a group of hormones that include epinephrine, norepinephrine, and dopamine, so they wanted to find out if the COMT gene affected people's susceptibility to incident cardiovascular disease such as myocardial infarction or ischemic stroke and also wanted to learn if genetic variation in COMT would influence aspirin's potential benefit.

any one of a group of sympathomimetic compounds composed of a catechol (1,2-dihydroxyphenyl) moiety carrying an alkyl side chain with an amine group on the side chain. Some catecholamines are produced naturally by the body and function as key neurological chemicals.

Catecholamines are the substances responsible for the fight-or-flight response to stressful situations. They are the chemicals that cause your heart to beat faster, sweat to coat your palms, and your emotions to change in an instant.

Catecholamines can serve as neurotransmitters, transferring signals from neuron to neuron, as well as hormones, which regulate physiological functions such as your heartbeat and breathing rate. Catecholamines mediate their function upon binding to catecholamine-specific receptors, such as dopamine receptors on neurons, and alpha- and beta-adrenergic receptors expressed on organs and tissues.

Though the stress hormone cortisol is very well studied, this is just part of the picture, as there is a simultaneous activation of the sympathetic nervous system that stimulates an increased output of catecholamines (epinephrine and norepinephrine) in both the brain and the adrenal medulla.

any of a group of sympathomimetic amines (including dopamine, epinephrine, and norepinephrine), the aromatic portion of whose molecule is catechol. The catecholamines play an important role in the body's physiological response to stress.
