Explore by type
Saturated
No double bonds. Stable, solid at room temperature.
Monounsaturated
A single double bond. Heart-friendly oils.
Polyunsaturated
Multiple double bonds. Omega-3 and omega-6 families.
Branched-Chain
Methyl-branched (iso / anteiso) fatty acids.
Furan Fatty Acids
Furan-ring antioxidants protecting against peroxidation.
Explore by omega family
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.
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.
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.
Omega 5s
First double bond five carbons from the methyl end. Uncommon: myristoleic acid, and the conjugated punicic acid of pomegranate seed oil.
Omega 7s
First double bond seven carbons from the methyl end. Palmitoleic acid is a “lipokine” — a fat that carries metabolic signals between tissues.
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
