Catecholamine refers to a class of monoamine neurotransmitters derived from catechol and belonging to the biogenic amine family, including dopamine, norepinephrine, and epinephrine. They are produced in the adrenal glands and nerve endings, influencing fight-or-flight responses and various neurological processes. In scientific contexts, the term encompasses both the neurotransmitters and related compounds with a catechol group and an amine side chain.
