 Synonyms & Historicals
Natural Gas .
Shale Gas .
Gas, Shale .
Gas, Natural .
A combustible, gaseous mixture of low-molecular weight PARAFFIN hydrocarbons, generated below the surface of the earth. It contains mostly METHANE and ETHANE with small amounts of PROPANE; BUTANES; and higher hydrocarbons, and sometimes NITROGEN; CARBON DIOXIDE; HYDROGEN SULFIDE; and HELIUM. (from McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed) .
Hydrocarbons .
Organic compounds that contain only carbon and hydrogen atoms. .
Aerosol Propellants .
Propellants, Aerosol .
Compressed gases or vapors in a container which, upon release of pressure and expansion through a valve, carry another substance from the container. They are used for cosmetics, household cleaners, and so on. Examples are BUTANES; CARBON DIOXIDE; FLUOROCARBONS; NITROGEN; and PROPANE. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed) .
Aryl Hydrocarbon Hydroxylases .
Microsomal Monooxygenases .
Xenobiotic Monooxygenases .
Hydroxylases, Aryl Hydrocarbon .
Monooxygenases, Microsomal .
Monooxygenases, Xenobiotic .
A large group of cytochrome P-450 (heme-thiolate) monooxygenases that complex with NAD(P)H-FLAVIN OXIDOREDUCTASE in numerous mixed-function oxidations of aromatic compounds. They catalyze hydroxylation of a broad spectrum of substrates and are important in the metabolism of steroids, drugs, and toxins such as PHENOBARBITAL, carcinogens, and insecticides. .
Hydrocarbons, Aromatic .
Aromatic Hydrocarbons .
Organic compounds containing carbon and hydrogen in the form of an unsaturated, usually hexagonal ring structure. The compounds can be single ring, or double, triple, or multiple fused rings. .
Bicarbonates .
Bicarbonate Ion .
Carbonic Acid Ions .
Hydrogen Carbonate .
Carbonate, Hydrogen .
Carbonates, Hydrogen .
Ions, Bicarbonate .
Ions, Carbonic Acid .
Bicarbonate Ions .
Hydrogen Carbonates .
Inorganic salts that contain the -HCO3 radical. They are an important factor in determining the pH of the blood and the concentration of bicarbonate ions is regulated by the kidney. Levels in the blood are an index of the alkali reserve or buffering capacity. .
Hydrocarbons, Acyclic .
Acyclic Hydrocarbons .
Organic compounds composed exclusively of carbon and hydrogen where no carbon atoms join to form a ring structure. .
Chemistry, Organic .
Organic Chemistry .
The study of the structure, preparation, properties, and reactions of carbon compounds. (McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed) .
