The first four seem to be involved in the hydroxylation of toluene to benzyl alcohol. CYP2E1 seems to be the primary enzyme in the hydroxylation of toluene, accounting for roughly 44% of toluene metabolism; [1] however, there is a great deal of ethnic variability, in the Finnish population for example the primary enzyme is CYP2B6.
Toluene is also found in cigarette smoke and car exhaust. If not in contact with air, toluene can remain unchanged in soil or water for a long time. [39] Toluene is a common solvent, e.g. for paints, paint thinners, silicone sealants, [40] many chemical reactants, rubber, printing ink, adhesives (glues), lacquers, leather tanners, and ...
Toluene (or methylbenzene) is a common chemical found in chemistry laboratories. An alkylbenzene is a chemical compound that contains a monocyclic aromatic ring attaching to one or more saturated hydrocarbon chains. [1] Alkylbenzenes are derivatives of benzene, in which one or more hydrogen atoms are replaced by alkyl groups.
Heteroarenes are aromatic compounds, where at least one methine or vinylene (-C= or -CH=CH-) group is replaced by a heteroatom: oxygen, nitrogen, or sulfur. [3] Examples of non-benzene compounds with aromatic properties are furan, a heterocyclic compound with a five-membered ring that includes a single oxygen atom, and pyridine, a heterocyclic compound with a six-membered ring containing one ...
The terms atherosclerosis and arteriosclerosis sound similar but are slightly different in meaning. Atherosclerosis is a type of arteriosclerosis. It refers to the build-up of plaque in blood vessels.
food options be positioned first in cafeterias, thereby inducing consumers to take more healthy food without limiting the availability of other choices. We explore these factors in a field study examining meal choices in a familiar restaurant. Methods During lunch hours, customers entering a Subway restaurant were approached and offered
Ecosystem food chains can be affected due to a decrease in algae productivity therefore threatening certain species. [24] Oil is "acutely lethal" to fish - that is, it kills fish quickly, at a concentration of 4000 parts per million [25] (0.4%). The toxicity of petroleum related products threaten human health.
Like many other carbonyl compounds, acetaldehyde tautomerizes to give an enol (vinyl alcohol; IUPAC name: ethenol): CH 3 CH=O ⇌ CH 2 =CHOH ∆ H 298,g = +42.7 kJ/mol The equilibrium constant is 6 × 10 −7 at room temperature, thus that the relative amount of the enol form in a sample of acetaldehyde is very small.
