Catechol. 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. [1] Catechol can be either a free molecule or a substituent of a larger molecule, where it represents a 1,2 ...
Catechol (/ ˈ k æ t ɪ tʃ ɒ l / or / ˈ k æ t ɪ k ɒ l /), also known as pyrocatechol or 1,2-dihydroxybenzene, is an organic compound with the molecular formula C 6 H 4 (OH) 2. It is the ortho isomer of the three isomeric benzenediols .
Catechol-O-methyltransferase (COMT; EC 2.1.1.6) is one of several enzymes that degrade catecholamines (neurotransmitters such as dopamine, epinephrine, and norepinephrine), catecholestrogens, and various drugs and substances having a catechol structure. [7] In humans, catechol-O-methyltransferase protein is encoded by the COMT gene. [8]

Mammalian siderophores, specifically catechols, can be found in the human gut and in siderophores, such as enterobactin, and serve as iron-binding moieties. [5] [26] Catechol resembling molecules can act as iron ligands in the cell and in systematic circulation, allowing siderocalin to bind to the iron-catechol complex. [27]
A dopamine molecule consists of a catechol structure (a benzene ring with two hydroxyl side groups) with one amine group attached via an ethyl chain. [14] As such, dopamine is the simplest possible catecholamine, a family that also includes the neurotransmitters norepinephrine and epinephrine. [15]
The deformed brain was found inside a roughly 2,600-year-old decapitated head that was excavated from a waterlogged pit in the U.K. in 2008. The image in the post is from a research paper about ...
This seemed to clarify the fate of the catecholamines in the body, but in 1956 Blaschko suggested that, because the oxidation was slow, "other mechanisms of inactivation … will be found to play an important part. Here is a gap in our knowledge which remains to be filled."
