Definition

1. Noun:
   • A monosaccharide having six carbon atoms and a ketone group: A "ketohexose" is a specific type of simple sugar (monosaccharide). Its molecular structure is defined by containing exactly six carbon atoms and one ketone functional group (C=O).

Usage Examples

• Noun:
  • Fructose is a common ketohexose found in many fruits.
  • The biochemist identified the sugar as a ketohexose based on its chemical structure.

Advanced Usage

• In Biochemical Contexts: The term is primarily used in scientific fields like chemistry and biochemistry to classify and discuss sugars.
  • The metabolism of a ketohexose like fructose follows a different pathway than that of an aldohexose like glucose.

Variants and Related Words

• Monosaccharide (n): The broader category of simple sugars to which ketohexoses belong.
• Aldohexose (n): A contrasting type of hexose sugar containing an aldehyde group instead of a ketone group (e.g., glucose).
• Hexose (n): A monosaccharide with six carbon atoms, which includes both aldohexoses and ketohexoses.
• Fructose (n): The most well-known and nutritionally significant ketohexose.

Synonyms

• Six-carbon ketose: A more descriptive chemical synonym.
