Exempel på hur man kan använda CATECHOL i en mening

• Any compound having a catechol structure, like catecholestrogens and catechol-containing flavonoids, are substrates of COMT.
• Generally, it is a chemical reaction involving polyphenol oxidase (PPO), catechol oxidase, and other enzymes that create melanins and benzoquinone from natural phenols.
• Crown ethers are much broader than the oligomers of ethylene oxide; an important group are derived from catechol.
• 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.
• About 20,000 tonnes of catechol are now synthetically produced annually as a commodity organic chemical, mainly as a precursor to pesticides, flavors, and fragrances.
• Semiquinones (or ubisemiquinones, if their origin is ubiquinone) are free radicals resulting from the removal of one hydrogen atom with its electron during the process of dehydrogenation of a hydroquinone, such as hydroquinone itself or catechol, to a quinone or alternatively the addition of a single hydrogen atom with its electron to a quinone.
• Several of these have pheromonal activity, of which the phenols 4-ethylphenol and catechol and the ketones acetophenone and 3-hydroxyacetophenone are strongest.
• Enzymes that regulate the biosynthesis or metabolism of dopamine such as aromatic L-amino acid decarboxylase or DOPA decarboxylase, monoamine oxidase (MAO), and catechol O-methyl transferase (COMT) may be referred to as dopaminergic as well.
• A strain of the bacterium Pseudomonas mendocina metabolises benzoic acid, yielding 1,2-benzoquinone via catechol.
• Guaiacol can be synthesized by the dimethylation of catechol followed by selective mono-demethylation.
• Some trace phenols in argan oil include caffeic acid, oleuropein, vanillic acid, tyrosol, catechol, resorcinol, (−)-epicatechin and (+)-catechin.
• Catechol, for example, is synthesized from o-hydroxy and o-alkoxy phenyl aldehydes and ketones, and is used as the starting material for synthesis of several compounds, including the catecholamines, catecholamine derivatives, and 4-tert-butylcatechol, a common antioxidant and polymerization inhibitor.
• Polyphenol oxidases are a family of di-copper metalloenzymes that include tyrosinase and catechol oxidase.
• The two enzymes were identified to be a part of two separate catechol dioxygenase families: 1,2-CTD was classified as an intradiol dioxygenase while 2,3-CTD was classified as an extradiol dioxygenase.
• For instance, scaffolded histidine residues mimic certain metalloproteins and enzymes such as hemocyanin, tyrosinase, and catechol oxidase.
• The reaction is catalysed by methyltransferases (Mtases) and modifies DNA, RNA, proteins and small molecules, such as catechol for regulatory purposes.
• The catechol dioxygenases, some of the most well-studied dioxygenase enzymes, use dioxygen to cleave a carbon-carbon bond of an aromatic catechol ring system.
• strain DO, p-Chlorocresol was degraded aerobically either by dehalogenation followed by catechol degradation pathway, or methyl oxidation to 4-chlorobenzoate.
• The allergenic agent of litre is 3–pentadecyl (10–enyl) catechol (litreol), an urushiol similar in structure to the allergens from poison oak and poison ivy.
• Other metabolic pathways of dopamine metabolism include methylation by catechol O-methyltransferase (COMT) into 3-methoxytyramine and β-hydroxylation by dopamine β-hydroxylase (DBH) into norepinephrine.
