| Common Name | 3-Hydroxyoctanoic acid |
|---|
| Description | 3-Hydroxyoctanoic acid (CAS: 14292-27-4) is an organic 3-hydroxy dicarboxylic acid, a metabolite of medium-chain fatty acid oxidation found in human urine. It is believed that urinary 3-hydroxy dicarboxylic acids are derived from the omega-oxidation of 3-hydroxy fatty acids and the subsequent beta-oxidation of longer-chain 3-hydroxy dicarboxylic acids. (PMID:1870421 ). 3-Hydroxyoctanoic acid has been identified in the human placenta (PMID: 32033212 ). |
