Catecholamine - Wikipedia
A catecholamine (/ ˌ k æ t ə ˈ k oʊ l ə m iː n /; abbreviated CA) is a monoamine neurotransmitter, an organic compound that has a catechol (benzene with two hydroxyl side groups next to each other) and a side-chain amine.

Catecholamines - Basic Neurochemistry - NCBI Bookshelf
The catecholamines dopamine (DA), norepinephrine (NE) and epinephrine are neurotransmitters and/or hormones in the periphery and in the central nervous system (CNS) (for reviews, see [1, 2]). NE is a neurotransmitter in the brain as well as in postganglionic, sympathetic neurons.
Understanding Catecholamines and Their Functions
2024年8月22日 · Catecholamines are a group of neurotransmitters and hormones that share a similar chemical structure and play vital roles in the human body. They are synthesized from the amino acid tyrosine and are classified as monoamines due to their single amine group.
Catecholamines 101 - PMC
Most pheochromocytomas secrete predominantly NE, many produce both NE and EPI, and more rarely others secrete predominantly EPI. The differences in catecholamine secretion reflect differences in expression of catecholamine biosynthetic enzymes and can explain differences in presenting symptoms.
The catecholamine system in health and disease —Relation to …
Biogenic amines that possess a 3,4-dihydroxyphenyl (catechol) nucleus are generally called catecholamines (CAs). Three CAs exist in vivo, i.e., dopamine, noradrenaline (norepinephrine), and adrenaline (epinephrine), all of which are derivatives of 3,4-dihydroxyphenylethylamine.
Catecholamine - an overview | ScienceDirect Topics
Catecholamines, which include dopamine, epinephrine, and norepinephrine, are neurotransmitters and hormones produced in response to stress by the sympathetic-adrenomedullary axis and adrenal gland, respectively. After the stress response has been initiated, catecholamines continue to circulate (Brown, 2006).
