Definition

Noun: 1. A type of organic compound: Any of a class of aromatic compounds characterized by a structure containing two oxygen atoms double-bonded to a benzene ring, typically forming yellow crystals. 2. Biologically important substance: Several quinones function as vital biological coenzymes, electron acceptors, or vitamins (like Vitamin K) in living organisms. 3. Industrial chemical: Quinones are used in the manufacture of dyes and other chemical products.

Usage Examples

• The chemist synthesized a quinone to study its electrochemical properties.
• Ubiquinone, a type of quinone, plays a crucial role in cellular energy production.
• This dye's vibrant color originates from a quinone derivative.

Advanced Usage

• "Quinone moiety": Refers to the specific quinone functional group within a larger, more complex molecule.
  • The protein's activity depends on the presence of a quinone moiety.
• "Quinone-hydroquinone couple": Describes a redox pair where a quinone and its reduced form (hydroquinone) are interconvertible, important in electrochemistry and biochemistry.
  • The electron transfer involves the quinone-hydroquinone couple.

Variants and Related Words

• Benzoquinone (n): The simplest quinone, where the oxygenated ring is a benzene ring.
• Ubiquinone (n): A specific quinone (also called coenzyme Q) essential for electron transport in mitochondria.
• Hydroquinone (n): The reduced, diol form of a quinone.

Synonyms
