| Common Name | Ricinoleic acid |

| Description | Ricinoleic acid, also known as 12-hydroxyoleate or ricinoleate, belongs to the class of organic compounds known as long-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Ricinoleic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, Ricinoleic acid has been detected, but not quantified in, a few different foods, such as corns, fats and oils, and fruits. This could make ricinoleic acid a potential biomarker for the consumption of these foods. Ricinoleic acid is found in Artocarpus integer, Azima tetracantha, Brunfelsia americana, Cephalocroton cordofanus, Claviceps purpurea , Cordia sinensis, Crotalaria pallida, Crotalaria retusa, Ganoderma lucidum , Hevea brasiliensis, Lesquerella densipila, Linum mucronatum, Platycodon grandiflorus, Ricinus communis , Ricinus opp. and Trichodesma zeylanicum. Ricinoleic acid was first documented in 1982 (PMID: 6948953). A hydroxy fatty acid that is (9Z)-octadec-9-enoic (oleic) acid carrying a hydroxy substituent at position 12 (PMID: 11050297). |
