compound

 [kom´pownd]
1. made up of diverse elements or ingredients.
2. a substance made up of two or more materials.
3. in chemistry, a substance made up of two or more elements in union. The elements are united chemically, which means that each of the original elements loses its individual characteristics once it has combined with the other element(s). When elements combine they do so in definite proportions by weight; this is why the union of hydrogen and oxygen always produces water. Sugar, salt, and vinegar are examples of compounds.

Organic compounds are those containing carbon atoms; inorganic compounds are those that do not contain carbon atoms.
clathrate c's inclusion complexes in which molecules of one type are trapped within cavities of another substance, such as within a crystalline lattice structure or large molecule.
quaternary ammonium compound an organic compound containing a quaternary ammonium group, a nitrogen atom carrying a single positive charge bonded to four carbon atoms, e.g., choline.
