What is dextrose?


Dextrose, commonly known as glucose, is the crystalline form of Glucose. Chemically it is a Monosaccharide (Simple sugar) with the molecular formula C₆H₁₂O₆. Glucose plays a central role in human energy metabolism.

Chemical classification and properties

feature Description
Chemical name Glucose/dextrose
class Monosaccharide (simple sugar)
Molecular formula C₆H₁₂O₆
Primary function Central energy source in metabolism
Storage form Glycogen (in liver and muscles)


Physiological significance

  • Energy supply: Glucose is an important source of energy for body cells.
  • Storage: Excess glucose is called Glycogen stored in the liver and muscles.
  • Own production: The body can produce glucose itself when needed.
  • Availability: As a simple sugar, glucose is available to the body without prior breakdown.

Effect in the organism

  1. Absorption: Absorbed into the bloodstream via the small intestine.
  2. Blood glucose level: Increase in glucose concentration in the blood.
  3. Energy production: Used by body cells to generate energy.
  4. Storage: Conversion of unnecessary amounts into glycogen.

Comparison with other types of sugar

type of sugar Structure Classification
Dextrose Simple sugars Available directly
Sucrose Disaccharide (glucose + fructose) Prior split required
Maltodextrin Glucose chains Multi-stage dismantling
Strength Polysaccharide Complex degradation process

Application context

  • Sports: Use as an ingredient in carbohydrate-containing drinks.
  • Diabetes context: Related to Hypoglycemia is often called glucose.
  • Food industry: Used in beverages, baked goods and confectionery.
  • Legal status: Classified as a food ingredient in the EU.
