molecule

[mol′əkyo̅o̅l]
Etymology: L, molecula, small mass
the smallest unit that exhibits the properties of an element or compound. A molecule is composed of two or more atoms that are covalently bonded. See also atom, compound.

molecule

The smallest unit of a substance that can exist alone and retain its core chemical and physical characteristics.

trivial name

A popular, working, or common name for a thing or process that has a formal name. See CD, DSM-IV, EC, SI.
Trivial name
Disease–eg, Lou Gehrig's disease for amyotrophic lateral sclerosis
Molecule–eg, Teflon for polytetrafluoroethylene
Organ–eg, anterior pituitary for adenohypophysis
Structure–eg, vocal cord for vocal fold–plica vocalis, or fallopian tube for tuba uterina, which is not standard nomenclature or based on 'official' rules delineated by international agencies or organizations–eg, American Psychiatric Association, Enzyme Commission, the International System, Terminologia Anatomica, etc
