Definition

1. Noun:
   • A type of monosaccharide sugar: A "hexose" is a simple sugar (monosaccharide) that contains six carbon atoms in each of its molecules. It is a fundamental building block in biochemistry.

Examples of Usage

• Noun:
  • Glucose and fructose are both common hexoses found in nature.
  • The chemical formula for a hexose is often C₆H₁₂O₆.

Advanced Usage

• In biochemical pathways: Hexoses are crucial substrates in metabolic processes like glycolysis.
  • The breakdown of the hexose glucose provides energy for cellular functions.

Variants and Related Words

• Monosaccharide (n): The broader category of simple sugars to which hexoses belong.
• Aldohexose (n): A subclass of hexoses where the carbonyl group is an aldehyde (e.g., glucose).
• Ketohexose (n): A subclass of hexoses where the carbonyl group is a ketone (e.g., fructose).

Synonyms

• Six-carbon sugar: A descriptive synonym emphasizing the atomic structure.
• Monosaccharide (with six carbons): A more general term with a specific qualifier.

Related Phrases and Compounds

• Hexose phosphate: A hexose molecule that has been phosphorylated, often an intermediate in metabolism.
  • Glucose-6-phosphate is a key hexose phosphate.

Notes on Meaning

• The term "hexose" is primarily used in scientific contexts, especially chemistry and biology. It is not typically used in everyday conversation. Its meaning is precise and refers specifically to the six-carbon structure of the sugar molecule.

Noun

1. a monosaccharide that contains six carbon atoms per molecule
