What it is Filled

A fatty acid with one or more carbon-carbon double or triple bonds within its chain, including fatty acids with triple bonds and familiar double-bond examples such as monounsaturated oleic acid and polyunsaturated linoleic acid, alpha-linolenic acid, EPA and DHA; cis and trans forms of double bonds differ in effects.

Why it exists Filled

Let an agent handle unsaturated fatty acids by structure, food sources, labelling and health information, without personal dietary advice.

Distinguishing features Filled

  • Its carbon chain contains at least one carbon-carbon double or triple bond.
  • These fatty acids are usually liquid at room temperature.
  • Some are essential in the diet.
  • They are prone to oxidation.

What robots and AI may and may not do Filled

Must not

  • Give personal diet advice or prescribe a fat intake for a person.
  • Repeat health claims about oils that food authorities have not accepted.
  • Advise using oil that is rancid or has been heated past its smoke point for food.
  • Present one oil as a cure or a danger beyond the evidence.

Only with a human decision

  • Any dietary change for a person with a heart or metabolic condition.

May

  • Explain the chemistry of unsaturated fatty acids and read fat declarations on labels.
  • Advise on storage that limits oxidation, from food safety guidance.

Moral aspects Filled

  • Fat advice has swung with fashion and marketing, and people's health decisions follow it.
  • Oxidised fats degrade food quality and may harm health.

Who is affected

  • Consumers reading labels
  • People managing heart conditions
  • Food producers and retailers

Owners Filled

Steward

Nobody owns the substances; food authorities set labelling and health claim rules.

Master systems

  • National food composition and labelling records

What else AI and robots need to interact with it Filled

Identity and identifiers required Filled

  • Vercy registry: vr.tr.unsaturated-fatty-acid
  • Wikidata: Q2250497 (https://www.wikidata.org/wiki/Q2250497)

Direct properties required Filled

  • Molar mass: g/mol - Calculate from the molecular formula of the identified fatty acid because chain length and unsaturation vary across the class.
  • Melting temperature: deg C - Measure by thermal analysis and report chemical identity, purity and geometric configuration.
  • Density: g/cm3 - Measure mass per calibrated volume and report temperature, physical state and sample composition.

Recognition required Filled

  • Structural representations show at least one carbon-carbon double or triple bond within the fatty acid chain.
  • Double-bond examples include monounsaturated and polyunsaturated fatty acids.
  • Omega numbering describes double-bond positions relative to the methyl end.
  • Saturated fatty acids have no carbon-carbon double or triple bonds within their chains.
  • Liquid oils at room temperature in most cases.

Capabilities and actions required Filled

  • classify fatty acids by double bonds
  • read fat labels
  • identify omega-3 and omega-6 sources
  • understand trans fat rules

Hazards and failure modes required Filled

  • Rancidity through oxidation
  • Agents giving personal diet advice
  • Misleading health claims

Standards and interfaces required Filled

  • EU trans fat limit regulation 2019/649
  • Nutrition labelling rules
  • National dietary guidelines

Context of use required Filled

  • Nutrition, food science and biology of cell membranes.
  • monounsaturated fatty acids
  • omega-3 fatty acids
  • omega-6 fatty acids
  • trans fatty acids
  • conjugated fatty acids

Sources Filled

  1. Wikidata item Q2250497: unsaturated fatty acid - identity and sense of the item
  2. Wikipedia: Unsaturated fatty acid - general description of the item

Open questions

  • Should omega-3 and omega-6 be separate entries?
  • How should dietary guidelines be localised?
  • How should trans fats be split off?
