    en.wikipedia.org/wiki/Catecholamine

    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 ...

    There are three structural isomers: 1,2-dihydroxybenzene (the ortho isomer) is commonly known as catechol, 1,3-dihydroxybenzene (the meta isomer) is commonly known as resorcinol, and 1,4-dihydroxybenzene (the para isomer) is commonly known as hydroquinone. [1]

    Figure 1. The overall reaction of catechol 1,2-dioxygenase. Using a non-heme iron(III) complex, 1,2-CTD is able to oxidatively cleave catechol into cis,cis-muconic acid. More specifically, 1,2-CTD is an intradiol dioxygenase, a family of catechol dioxygenases that cleaves the bond between the phenolic hydroxyl groups of catechol using an Fe 3 ...

    Their investigation constitutes a major chapter in the history of physiology, biochemistry, and pharmacology. Adrenaline was the first hormone extracted from an endocrine gland and obtained in pure form, before the word hormone was coined. [2] Adrenaline was also the first hormone whose structure and biosynthesis was discovered.

  8. Catechol-O-methyltransferase - Wikipedia

    en.wikipedia.org/wiki/Catechol-O-methyltransferase

    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]

    en.wikipedia.org/wiki/Catechol_dioxygenase

    Catechol dioxygenases are metalloprotein enzymes that carry out the oxidative cleavage of catechols.This class of enzymes incorporate dioxygen into the substrate.Catechol dioxygenases belong to the class of oxidoreductases and have several different substrate specificities, including catechol 1,2-dioxygenase (EC 1.13.11.1), catechol 2,3-dioxygenase (EC 1.13.11.2), and protocatechuate 3,4 ...
