Full profile 

Explore by type

Palmitic acid

Saturated

No double bonds. Stable, solid at room temperature.

23 fatty acids
Oleic acid

Monounsaturated

A single double bond. Heart-friendly oils.

18 fatty acids
Linoleic acid

Polyunsaturated

Multiple double bonds. Omega-3 and omega-6 families.

28 fatty acids
Iso-pentadecylic acid

Branched-Chain

Methyl-branched (iso / anteiso) fatty acids.

15 fatty acids
Furan FA 11D5

Furan Fatty Acids

Furan-ring antioxidants protecting against peroxidation.

8 fatty acids

Explore by omega family

α-Linolenic acid

Omega 3s

First double bond three carbons from the methyl end. Broadly anti-inflammatory: the essential ALA, plus the marine long-chain EPA and DHA.

11 fatty acids
Linoleic acid

Omega 6s

First double bond six carbons from the methyl end. Linoleic acid is the essential parent; intake climbed through the 20th century with vegetable oils.

13 fatty acids
Oleic acid

Omega 9s

First double bond nine carbons from the methyl end. Non-essential — the body makes them — and oleic acid is the most abundant fatty acid in the body.

7 fatty acids
Myristoleic acid

Omega 5s

First double bond five carbons from the methyl end. Uncommon: myristoleic acid, and the conjugated punicic acid of pomegranate seed oil.

3 fatty acids
Palmitoleic acid

Omega 7s

First double bond seven carbons from the methyl end. Palmitoleic acid is a “lipokine” — a fat that carries metabolic signals between tissues.

7 fatty acids
Cetoleic acid

Omega 11s

First double bond eleven carbons from the methyl end. Long-chain monounsaturates such as gondoic and cetoleic acid, enriched in fish oils.

Roadmap

Where the database is today, and what is being built next. It is a working draft of current intentions — not a set of commitments.

Here today

  • Full fatty-acid profiles Structure, names, chemistry, IDs, isomers and top dietary sources for every entry.
  • Interactive 2D & 3D models Rotate the real molecule, or step through the chain bond by bond.
  • Cross-referenced IDs One click to PubChem, LIPID MAPS, ChEBI, HMDB, KEGG and more.
  • Food Profiles Line foods up side by side and compare their saturated, monounsaturated and polyunsaturated split.
  • Biosynthesis pathways An interactive canvas showing where a fatty acid is made, and from what.
  • Metabolites Follow fatty acids downstream into aldehydes and other peroxidation products — 4-HNE, acrolein, hexanal — with their precursors and references.

Coming next

  • Learn & Topics Plain-language explainers that connect the data to the nutrition science, cross-linked to every fatty acid.
  • Health Associations Health effects organised by body system, each with its mechanism and the supporting literature — null results included.
  • Roles & Metabolism What a fatty acid actually does: energy, membranes, signalling and the rest of the metabolic spine.
  • Baby Formula Profiles The full fatty-acid breakdown of stage-1 infant formulas — LA, ALA, DHA and the omega-6:3 ratio — side by side.
  • Proteins Explorer The enzymes and carriers behind fatty-acid metabolism — FASN, the desaturases, thioesterases — and what they act on.
  • Open data & API Grow the download into a documented, versioned open dataset with a lightweight API.
