What it is Filled

A simple sugar with the formula C6H12O6, the most abundant monosaccharide, made by plants in photosynthesis and used by most organisms as a main source of energy; the natural form is D-glucose, also called dextrose.

Why it exists Filled

Let an agent identify glucose by its chemical identifiers and properties, explain its role in metabolism and food, and route health questions about blood sugar to clinicians.

Distinguishing features Filled

  • An aldohexose; fructose has the same formula but is a ketose.
  • D-glucose is the natural form; L-glucose is rare and not metabolised in the same way.
  • In water the alpha and beta ring forms interconvert through a trace open-chain form (mutarotation).
  • Glucose syrup is a mixture of saccharides from starch, not pure glucose.

What robots and AI may and may not do Filled

Must not

  • give insulin or medication doses
  • diagnose diabetes or hypoglycaemia
  • advise ignoring a dangerous blood glucose reading

Only with a human decision

  • any treatment decision
  • emergency response to a very low or very high reading

May

  • give chemical data and identifiers
  • explain glucose in metabolism and food in general terms
  • convert measurement units

Moral aspects Filled

  • public health and sugar consumption
  • safety of people with diabetes

Who is affected

  • people with diabetes
  • consumers

Owners Filled

Steward

nobody; a chemical substance, with records kept by chemical registries

Master systems

  • CAS Registry
  • PubChem
  • ChEBI

Links to other meta-models Filled

parent

  • Q1077067 - registry parent class

related

  • monosaccharide - an aldohexose
  • starch - polymer of glucose
  • fructose - same formula, different structure
  • blood sugar - clinical measurement
  • glucose syrup - a mixture made from starch

What else AI and robots need to interact with it Filled

Identity and identifiers required Filled

  • Vercy registry: vr.tr.glucose
  • Wikidata: Q37525 (https://www.wikidata.org/wiki/Q37525)
  • CAS Registry Number: 50-99-7 D-glucose
  • PubChem CID: 5793 D-glucose
  • ChEBI: CHEBI:17234 glucose
  • molecular formula: C6H12O6

Direct properties required Filled

  • molar mass: 180.16 g/mol - anhydrous; the monohydrate C6H12O6.H2O is about 198.17
  • melting point: 146-150 degC - anhydrous alpha-D-glucose about 146; beta form about 150
  • solubility in water: about 1 g in 1.1 mL - anhydrous alpha-D-glucose at 25 degC
  • relative sweetness: 0.7-0.8 x sucrose

Recognition required Filled

  • Appearance is not diagnostic; identify the substance and form from documentation or analysis
  • Sold as white crystals or powder labelled dextrose
  • A white crystalline powder or colourless crystals, sweet tasting and soluble in water.

Capabilities and actions required Filled

  • give identifiers and basic physical data
  • explain its role in metabolism
  • convert blood glucose between units (mg/dL = mmol/L x 18.016), without interpreting the reading
  • describe its uses in food and industry

Hazards and failure modes required Filled

  • Hypoglycaemia and hyperglycaemia in people with diabetes
  • Dust explosion risk in bulk powder handling
  • Dental caries from frequent sugar intake

Standards and interfaces required Filled

  • European Pharmacopoeia monographs for glucose and glucose monohydrate
  • Codex Alimentarius Standard for Sugars, CXS 212-1999 (FAO/WHO), covering dextrose and glucose syrup
  • ISO 15197 requirements for blood glucose monitoring systems for self-testing

Context of use required Filled

  • Supplying energy to cells and serving as a building block of starch, cellulose and glycogen; used in food, medicine and fermentation.
  • D-glucose (dextrose)
  • L-glucose
  • alpha and beta anomers
  • anhydrous dextrose
  • dextrose monohydrate

Sources Filled

  1. Q37525 - identity of the registry item, labels and sitelinks
  2. Glucose - general description of the subject
  3. D-Glucose, PubChem CID 5793 - formula, molar mass, identifiers and properties
  4. glucose (CHEBI:17234) - ChEBI identifier
  5. ICSC 0865 - Glucose - CAS and EC numbers, appearance and combustible dust hazard
  6. ISO 15197:2013 - requirements for blood-glucose self-testing systems

Open questions

  • The registry merges many isomers and forms; should L-glucose stay merged here?
  • Reference ranges for blood glucose differ between guidelines; which source should the card cite?
