About this Database

An open reference for human nutritional fatty acids — their structure, food sources, metabolism, and health effects — covering the fatty acids that matter most in the human diet.

What's inside

The database currently catalogues 92 fatty acids, from the everyday saturated, monounsaturated, and polyunsaturated acids to the rarer branched-chain, cyclic, furan, and trans species. Every fatty acid has a profile page with its structure, identifiers, chemical properties, food sources, historical consumption, and the latest research from PubMed.

How to use it

  • Browse and filter all fatty acids by type, omega family, chain length, and more.
  • Category pages explain each type and family, with top food sources and intake trends.
  • Topics give plain-language explainers on the underlying nutrition science.

Sources & accuracy

Composition and identifier data are drawn from public sources such as USDA FoodData Central, PubChem, LIPID MAPS, and HMDB; historical-intake figures come from USDA Economic Research Service availability data and the published nutrition literature. We aim for accuracy but data may contain errors — always consult primary sources for critical use.
