| Common Name | Citronellic acid |
|---|
| Description | Citronellic acid, also known as rhodinic acid or citronellate, belongs to the class of organic compounds known as acyclic monoterpenoids. These are monoterpenes that do not contain a cycle. Citronellic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Citronellic acid exists in all living organisms, ranging from bacteria to humans. Citronellic acid is a fatty, floral, and grassy tasting compound. Outside of the human body, Citronellic acid is found, on average, in the highest concentration within lemon balms and peppermints. Citronellic acid has also been detected, but not quantified in, a few different foods, such as cardamoms, lemon grass, and mandarin orange (clementine, tangerine). This could make citronellic acid a potential biomarker for the consumption of these foods. Citronellic acid is found in Callitris glauca, Callitris intratropica, Chamaecyparis obtusa, Daphne papyracea, Eucalyptus albens, Eucalyptus tereticornis, Juniperus spp., Pelargonium graveolens, Pelargonium vitifolium and Thujopsis dolabrata. Citronellic acid was first documented in 1990 (PMID: 2265211). A monounsaturated fatty acid that is oct-6-enoic acid carrying methyl groups at positions 3 and 7 (PMID: 18605213) (PMID: 20429462) (PMID: 20568624) (PMID: 29393872). |
