In fiction, Adamant is referred to in the film Forbidden Planet (as "adamantine steel"), many books (such as The Adventures of Tom Sawyer, The Faerie Queene, Gulliver's Travels, His Dark Materials, The Lord of the Rings, Mathilda by Mary Shelley, and A Midsummer Night's Dream) and many games (such as Dungeons & Dragons, Final Fantasy and ...
Mellitic acid, which contains no C-H bonds, is considered a possible organic compound in Martian soil. [15] Terrestrially, it, and its anhydride, mellitic anhydride, are associated with the mineral mellite (Al 2 C 6 (COO) 6 ·16H 2 O). A slightly broader definition of the organic compound includes all compounds bearing C-H or C-C bonds.
Organic chemistry – study of the structure, properties, composition, mechanisms, and reactions of organic compounds. An organic compound is defined as any compound based on a carbon skeleton. Biochemistry – study of the chemicals, chemical reactions and chemical interactions that take place in living organisms. Biochemistry and organic ...
All compounds are substances, but not all substances are compounds. A chemical compound can be either atoms bonded together in molecules or crystals in which atoms, molecules or ions form a crystalline lattice. Compounds based primarily on carbon and hydrogen atoms are called organic compounds, and all others are called inorganic compounds.
Isaac Asimov, the biochemist and science fiction writer, suggested in 1981 that poly-lipids could form a substitute for proteins in a non-polar solvent such as methane. [51] Lakes composed of a mixture of hydrocarbons, including methane and ethane , have been detected on the surface of Titan by the Cassini spacecraft .
In pharmacology, an important group of organic compounds is small molecules, also referred to as 'small organic compounds'. In this context, a small molecule is a small organic compound that is biologically active but is not a polymer. In practice, small molecules have a molar mass less than approximately 1000 g/mol.
Ionic compounds without these ions are also known as salts and can be formed by acid–base reactions. Ionic compounds can also be produced from their constituent ions by evaporation of their solvent, precipitation, freezing, a solid-state reaction, or the electron transfer reaction of reactive metals with reactive non-metals, such as halogen ...
Furan is a heterocyclic organic compound, consisting of a five-membered aromatic ring with four carbon atoms and one oxygen atom. Chemical compounds containing such rings are also referred to as furans. Furan is a colorless, flammable, highly volatile liquid with a boiling point close to room temperature.
