The prefix "hex" is derived from the fact that there are 6 carbon atoms in the molecule, while the "-ene" suffix denotes that there is an alkene present—two carbon atoms are connected via a double bond.Sealcoat: Sealcoat is a bituminous liquid mixture that is applied to asphalt.Constitutive enzyme: Constitutive enzymeshttp://goldbook.iupac.Green coke: Green coke (raw coke) is the primary solid carbonization product from high boiling hydrocarbon fractions obtained at temperatures below 900 K. It contains a fraction of matter that can be released as volatiles during subsequent heat treatment at temperatures up to approximately 1600 K.Gas chromatography–mass spectrometry: right|300 px|Example of a GC-MS instrument|thumbCreosoteAcenaphthyleneP-AnisidineElectron-capture mass spectrometry: Electron-capture mass spectrometry (EC-MS) is a type of mass spectrometry that uses electron capture ionization (ECI) to form negative ions from chemical compounds with positive electron affinities. The approach is particularly effective for electrophiles.Biotransformation: Biotransformation is the chemical modification (or modifications) made by an organism on a chemical compound. If this modification ends in mineral compounds like CO2, NH4+, or H2O, the biotransformation is called mineralisation.List of keratins expressed in the human integumentary system: There are many different keratin proteins normally expressed in the human integumentary system.Musk xyleneBenzopyreneTransition metal benzyne complex: Transition metal benzyne complexes are organometallic complexes that contain benzyne ligands (C6H4). Unlike benzyne itself, these complexes are less reactive although they undergo a number of insertion reactions.Mutagen: In genetics, a mutagen is a physical or chemical agent that changes the genetic material, usually DNA, of an organism and thus increases the frequency of mutations above the natural background level. As many mutations can cause cancer, mutagens are therefore also likely to be carcinogens.TridecaneXenobiotic: A xenobiotic is a foreign chemical substance found within an organism that is not normally naturally produced by or expected to be present within that organism. It can also cover substances which are present in much higher concentrations than are usual.Occupational hygiene: Occupational (or "industrial" in the U.S.Dewar benzeneExhaust gasOctaneHassi R'Mel gas field: The Hassi R'Mel Gas Field is the largest gas field in Algeria and one of the largest gas fields in the world. It is located in the vicinity of Hassi R'Mel village, south of Algiers.Gemmatimonadetes: The Gemmatimonadetes are a family of bacteria, given their own phylum (Gemmatimonadetes). This bacterium makes up about 2% of soil bacterial communities and has been identified as one of the top nine phyla found in soils; yet, there are currently only six cultured isolates.ButanePentachloroethaneFresno County Public LibraryNankai Trough gas hydrate site: Nankai Methane Hydrate Site (or Japanese Methane Hydrate R&D Program at Nankai, Nankai Trough Methane Hydrate Site) is located in the Nankai Trough, Japan.Liquid paraffin (medicinal): Paraffin}}CyclopentadieneModel lipid bilayer: A model lipid bilayer is any bilayer assembled in vitro, as opposed to the bilayer of natural cell membranes or covering various sub-cellular structures like the nucleus. A model bilayer can be made with either synthetic or natural lipids.Briquette: A briquette (or briquet) is a compressed block of coal dust"briquette, n. 2.Benzo(a)fluoreneLiver sinusoid: A liver sinusoid is a type of sinusoidal blood vessel (with fenestrated, discontinuous endothelium) that serves as a location for the oxygen-rich blood from the hepatic artery and the nutrient-rich blood from the portal vein.SIU SOM Histology GIDevelopmental toxicity: Developmental toxicity is any structural or functional alteration, reversible or irreversible, which interferes with homeostasis, normal growth, differentiation, development or behavior, and which is caused by environmental insult (including drugs, lifestyle factors such as alcohol, diet, and environmental toxic chemicals or physical factors). Pathogens are generally included as well, despite some definitions not regarding biological organism as "toxic" by themselves.Chronic solvent-induced encephalopathy: Chronic solvent induced encephalopathy (CSE) is a condition induced by long-term exposure to organic solvents, typically in the workplace, that lead to a wide variety of persisting sensorimotor polyneuropathies and neurobehavioral deficits even after solvent exposure has been removed. This syndrome can also be referred to as "psycho-organic syndrome", "organic solvent syndrome", "chronic painter's syndrome", "occupational solvent encephalopathy", "solvent intoxication", "toxic solvent syndrome", "painters disease", "psycho-organic syndrome", "chronic toxic encephalopathy", and "neurasthenic syndrome".Exogenous bacteria: Exogenous bacteria are microorganisms introduced to closed biological systems from the external world.

It is known by the common name blackspotted topminnow.Ethyl groupTrail pheromone: Trail pheromones are semiochemicals secreted from the body of an individual to impact the behavior of another individual receiving it. Trail pheromones often serve as a multi purpose chemical secretion in which, it leads members of its own species towards a food source, while representing a territorial mark in the form of an allomone to organisms outside of their species.Particulates: Atmospheric particulate matter – also known as particulate matter (PM) or particulates – is microscopic solid or liquid matter suspended in the Earth's atmosphere.
