| Common Name | 2-Octenoic acid |
|---|
| Description | 2-Octenoic acid, also known as 2-octenoate, belongs to the class of organic compounds known as medium-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 4 and 12 carbon atoms. 2-Octenoic acid has 8 carbon atoms. 2-Octenoic acid is also known as an olefinic fatty acid carrying a double bond at position 2. It can exist in two isomeric forms, the cis and the trans form, with the trans or 2-E form being more abundant. 2-Octenoic acid is a relatively hydrophobic molecule with a water solubility of approximately 1 g/L. The 2E-isomer has a musty, sour, cheesy aroma and a fatty or waxy taste. 2-Octenoic acid is found in the human body and is naturally produced by hepatic microsomal oxidation of aliphatic aldehydes. 2-Octenoic acid has been detected in human urine and plasma (PMID 1883862 , 8087979 , 4086594 , 1417834 , 6480773 ). 2-Octenoic acid has also been identified as a potential pheromone excreted by the male abdominal glands of the cockroach Leucophaea maderae (PMID: 17200891 ). Outside the human body 2-Octenoic acid has been detected in coffee, cranberries, mushrooms, black tea and strawberries. It is also used as a food flavourant for baked goods and candies. |
